It would generate 5011.27 US Dollars if you left it to compound monthly for a period of 10 years.

1 of 1 million (calculate 1% of 1 million)

So now, let’s calculate what is 1% of 1 million? (One percent of one million?).

How can you calculate 1% of 1 million (in other words)? First of all, you should know that 1% implies 1 per 100, and one million is 1 followed by 6 zeroes.

You need to multiply the number by the percent and then divide the product by a hundred for calculating the percent of a particular number.

For simplification, here is a formula for you –

(Percent × Million) / 100

You should first multiply 1 million by one and then you should divide that product by 100 using the formula. 

Here is the complete mathematics to show you how to do it –

1 × 1 million = 1 Million

1 Million / 100 = 0.01 Million

There you have your answer! Now we will provide you the answer to 1% of 1 million in words (letters) followed by numbers (digits). We start with words –

Ten Thousand

Next, we will provide you the answer in numbers the way you would write it instead of saying it with all those words.

Once again, here is your answer to 1 percent of 1 million in numbers –


1 million seconds

Many people are lousy with numbers, especially the big and significant numbers.

Numbers such as trillions, billions, or millions are simply hazy notions of really significant numbers for many individuals.

You might actually witness their eyes glaze out and over by simply adding a dollar sign in front of these numbers.

For example, I hope that each one of you knows that a minute is made up of or equal to 60 seconds, and each one of you might also have a good sense that how long a second lasts.

Now if I ask you that how long will a million seconds lasts then do you have the answer to this question?

Here you go :

A million seconds will talk more than a week and a half to elapse (around 12 days).

Now, let’s move to the billion dollar question : How long will a billion seconds last?

A billion seconds will take around 32 years to elapse.

Moreover, a trillion seconds will take 31688 years to elapse.

You are required to start the timer from way back in 29673 B.C. for that to happen!

FYI, 1000000 arc-seconds =277.778 degrees.


100000 / 25 is equal to 40000 (forty thousand in words).

what is computer

Basically, a computer is a machine that is capable of getting data in a given form and having done a sequence of operations in accordance with a predetermined but variable set of instructions to deliver a result in the form of information.

It has turned into a personification in our day-to-day proceedings.  Whether elders, children or middle-aged people, everybody is relying on computers.

Computers were built with a purpose so that it can reduce the time of humans in executing tasks.

Computers were there and will be there before the end of our civilization.

Full Form of Computer

A computer is not an acronym and is the name of an electronic device.

But people refer computer as :-

COMPUTER stands for:-

C -> Commonly

O -> Operated

M -> Machine

P -> Particularly

U -> Used for

T -> Trade

E -> Education

R -> and Research

Types of Computer

On the basis of data handling capabilities, the computer is of three types:

Analog computer

Digital computer

Hybrid computer

On the basis of size, the computer is of five types:

1. Mainframe computer

2. Supercomputer

3. Miniframe or minicomputer

4. Workstation

5. Microcomputer

1. Mainframe computer

It is referred to as “large iron”It is a device that is used for processing jobs of large information.

2. Super computer

A computer that is used with a high level of performance compared to a general purposes computer device is known as a supercomputer.

In China, there are more than 219 supercomputers”. The United States of America has 116 nos. of supercomputers.

Japan has more than 29 supercomputers. India has 11 supercomputers out of the upper five hundred supercomputers.

It is used in the department of the computing field.

3. Minicomputer

Minicomputers are used for scientific and engineering computations and it is used for business.

4. Workstation

a powerful, single-user computer that is having a superior quality monitor and hi-fi microprocessor.

5. Microcomputer

A microcomputer is a microprocessor computer and its central processing unit.

Categories of the computer on basis of Computing

A computer has two primary categories:

Hardware: Physical structure that abodes a computer’s processor, memory, storage, transmission docks, and outermost devices.

Hardware is the real model that we can feel and tap on it.

Ex. RAM, Hard drive, and CD ROM

 Software: Includes Database Management and Applications software

VLC Media player, Ms Word, Picasa, Windows, Android, iOS, Language processors. These all are Softwares.

Parts of computer

Computers are having four parts:

1. Mouse

2. CPU

3. Monitor

4. CPU

1. Mouse

There are basically two types of mouse i.e. ball type and optical type. When we remove the bottom disk on ball-type mice, we see a cavity in which a hard spherical ball is placed and made easy to roll.

When the mouse is moved over a leveled surface, the ball rolls in the x and y-axis and accordingly rotates two pivots either clockwise or counterclockwise.

Rotation of these two pivots is replicated as the movement of the cursor on our screen based on ac/dc convertors and decoders.

While in newer optical mice, the led or laser light is made to glow over the surface over which it is placed on a certain angle of incidence.

This causes a reflex pattern to form which is seized by the sensing medium.

When the mouse is moved over the surface, the pattern of shadow moves in different directions according to the focus of the mouse.

This variation and longevity are replicated as movement regarding mouse, pointer.

Since it requires the formation of shadow patterns, such an optical mouse works on the surface with some amount of roughness.

Highly plain tables and notepaper never work well with optical mice as the shadow pattern never forms due to the scattering of light.

2. CPU(Central Processing Unit).

CPU is the “brain” of a computer. The central processing unit provides data to be managed and handled sent by the user.

Most of the time the user scrolls towards the key, the application is being carried out, or glance at the webpage, the specific code is made to study and comes again as reflux to the enjoyer.

The CPU works closely with the memory. Memory is a component that sends featured data to the device.

3. Monitor

A monitor is a bit of PC equipment that shows the video and illustrations data created by an associated PC through the PC’s video card.

A monitor which was previously and now implied to as a screen, the video showing the device, or watching movies or for playing online games.

Since there are so various kinds of monitors and approaches to utilize them, lots of assembled articles can assist one with catching through everything.

A Monitor is divided into five segments: Monitor Basics, Add or Connect a Monitor, Calibrate it yourself, Troubleshooting Issues, etc.

Monitors are implicit as a feature of the PC in workstations, tablets, books, and across the board work area machines

4. Keyboard

Different components of the Keyboard are

1- Alpha Numerical Key

2- Function Key

3 – Navigation Key

4- Control key

5- Numerical Key

1. Alpha Numerical Key

These keys are visible on the left-hand side of the keyboard it includes from A to Z alphabets and numbers from 0 to 9 and some special symbol, we can use the alphabets is capital by Dynamic capslocks key.

2. Function Key

The function keys are present at the top row of the keyboard we can find twelve functions of this key is various requisition to another.

3. Navigation Keys

This key is also which is visible in the middle portion of the keyboard, it helps to place the slider from one place to another place easily.

4. Control Keys

This key is used for controlling operations relating to tasks to be fulfilled on the computer. Some examples are ctrl, shift, etc.

5. Numerical Keys

This key is present on the right side of the keyboard and it helps the user to perform different types of mathematical calculations easily.

Today’s computers are smaller and amazingly powerful when compared with earlier computers.

They are having different variations that can be put on a table, in the knees, and in the hands.

History of Computer

The first known computer using that definition is the Antikythera mechanism which is dated to before 100BC and was built in Greece.

Its exact purpose is unknown but recently it has been asserted that it’s an accurate portrayal of the position of the planets & celestial bodies.

With the publication of Newton’s “Principal Mathematica” computation of orbits became possible.

The hand computations which led to the prediction of the comet of 1758, validated Newton’s math and physics.

The return of comet is an n-body problem. Only planets from Mercury through Saturn were known.

There was no analytical solution for more than two bodies. Many people took help of computers to make the computations.

 Halley’s Comet made a comeback in 1835 as a result of these computations.

Computation is different from the actual return date. This implied there were planets beyond Saturn!

With Napierian logarithms, the “Slide Rule” came into existence.

Every scientist and engineer had their own slide rule and then Hewlett Packard’s pocket calculator was discovered.

But in 1952 the Universal Automatic Computer which was designed for business application predicted the elections of President.

A prediction no one believed until later that the computer outguessed the experts made newspaper headlines.

The first programmable computer was designed by Charles Babbage in the 1830s, was mechanical rather than electronic.

Sadly it could never be constructed, and it wasn’t until World War II that British code breakers built Colossus, the world’s first computerized and fully automated computer.

Alan Turing was such a fantastic mathematician who being fascinated in breaking up of codes managed to construct a computer after the world war.

From science project to everyday tool

Scientists and Physicists were curious towards computers every other time. Interaction between humans and computers continued from the period of mouse to present age.

Douglas Engelbart invented mouse in 1960s.

Apple Macintosh computers were released in 1984 and it then became useful and more importantly in the capacity of ordinary man to carry out various tasks.

Highlights in the development of the computer

Computers made out as bigger frameworks of glass plugs and wires that occupied multiple rooms and weighed tons.

Now they can get set on semiconductor chips that is barely larger than an ant and are millions of times more powerful than the first ones.

The number of computers has increased a lot over time.

Urban myth has it that, in the 1950s, the head of IBM projected an international shop for lots of projected computers.

ARPANET was developed by the United States of America that allowed a few universities and the army for the computers in the US to talk to each other which helped in the foundation for the modern internet, the worldwide network that connects to a lot of computers – and people – to each other.

How computers work

When you first turn your computer on, the only thing it’s capable of doing is finding the BIOS (Basic Input Output System) ROM (Read Only Memory) chip on your mainboard.

A program is plugged onto the BIOS chip so that it knows where to seek for, and how to access the different drives.

The computer begins the start-up process. It loads coded programs and instructions executed on the BIOS chip into memory and carries out the instructions in order.

To view any actions being carried out on the monitor; the Pause key is pressed. The POST operation will be halted until you press the Escape key again.

Viruses and how to protect computer from it

This was with WINDOWS Operating Systems.

 After going through a long process of learning how to combat this virus attack.

Many people did not know about making a backup program yet and using the restore back to an earlier time only worked now and then.

Until someone found the backup programs to make a system disk back up, one started to reinstall my Windows operating system.

It got operated into a  new operating system again. Someone began to keep my data on an external drive so when the next viral attack happens; someone only had to reinstall the Operating system.

Someone looked on the internet to try to find a Windows Live disk that would boot on the DVD/CD drive, don’t bother looking &Windows never allowed it to be created.

However, someone did find a program called BART, which used XP as part of the program to boot from the DVD/CD drive and allow you to access the hard drive in the computer avoiding starting the normal operating system. It’s a good program.

Someone found the system backup program on BART and that was such a time saver.

The backup would back up the entire system disk. When you restored it, it formatted the drive and restored the system as it was at the time I backed it up. PERFECT!!!

Later someone tried LINUX and liked it.

I installed it on my computer as DUAL BOOT, and only use the LINUX for internet, the Windows-based operating system have their updates turned off. They never went to the internet in windows.

Further, the Windows operating System has Deep Freeze installed which prevents changes to the Windows operating system unless you want to make a change.

Now speaking from years of no virus attacks and still using games and programs that the newer Windows Operating Systemswon’t run.

There is another webpage that talks about why Linux is not nearly as vulnerable as Windows is to virus attacks

One strongly recommends that you make a SYSTEM DISK IMAGE BACKUP and put it in a safe place. Also, make a backup disk of your data files.

With a Windows Operating System, we must have to get an Antivirus program. Someone has no suggestion which one, they all have their flaws and if the virus is not on the menu, the program can’t find it, leaving you again, on your own.

Running Deep Freeze is not a fantastic implementation rather we have to work with it as it can’t discrepancy in the disk unless you give them a chance.

One can set a procedure to restore one’s system back up some week or just when one notices a problem with the operating system but make sure the restore will be of the date you made the backup.

If you have not updated it, one’s restore will be completely the same of that backup (of any previous time). Neither any fresh writing-off data will be there.

One also recommends saving data to an external drive leaving the operating system on the working drive, and use the open space as a temporary save then transfer the data to the external drive before shutting down the computer.

This is in regard if we have placed DEEP FREEZE because when you make the computer back in position and it starts up, any saves will be gone from the computer working drive.

Henceforth one should look into one’s backups and consider making a System Disk IMAGE Backup.

Study in Educational Institution

Students are taught computers from their schools.

In Colleges in Engineering Stream, there is a 4-year course and even research is there in the field of Artificial Intelligence, Machine Learning, Data Science.

Students are taught Python, C, C++, Java in their regular curriculum. Computer study is based on mostly Practical studies.

Students are first taught theory then the practical assignment is done on computers, Laptops, etc.

Students should learn the basics of programming which can be easier if they have the logic to crack.

Various IT firms come to the college for campus placements in the last year of college students.

They ask students to write the program on a piece of paper and also ask aptitude questions.

The human Resource department comes along with these IT firms checks the educational certificates of every student who sit in the campus and accordingly clarifies being fit to join the company and rejects if any discrepancy happens.

If they are placed in that campus after being selected they are asked to join after completion of college along with final results.

Upon joining they are paid handsome packages accordingly they are promoted to senior positions.

Bootstrap Alerts- Success, Warning, Error, Danger Messages

Alert messages are useful for the websites every now and then.

They might indicate some failed validation or notify a successful registration for the user.

Either way, their appearance is an important aspect to work on.

Bootstrap has many features for Alert Messages as well.

It provides the developers some easy ways in which they can create and style predefined alert messages.

The class, generally, used for the Alerts is the .alert class.

Bootstrap Alert Message Classes

There are the following contextual classes that can be used for different types of alerts:

.alert-primary: This is a primary alert to show information.

.alert-secondary: This is a grey background color alert box to show general information.

.alert-success: This alert message is used to represent a success message.

.alert-danger: Background color – Red. This indicates any dangerous i.e. potentially negative action.

.alert-warning: Background color – Yellow. This is different from alert-danger as this can be used to suggest some caution to avoid any potentially negative action rather than notifying it.

.alert-info: Background color – Light-blue. This is just a piece of information that the user needs to be notified about. Generally, any informative action is indicated using this alert.

.alert-light: This alert box is used to represent data in the light color alert box.

.alert-dark: This alert box represents data in the dark box.

Bootstrap alert messages
Fig: Bootstrap alert messages

Here’s the sample code for using these classes:

Bootstrap success message

Alert css code for bootstrap success message is

<div class="alert alert-success">

Bootstrap info

Alert info CSS is <div class="alert alert-info">

Bootstrap alert warning

We can create alert warnings by including .alert-warning CSS class

<div class="alert alert-warning">

Bootstrap warning color

Bootstrap warning color is FFF3CD in hexadecimal and rgb(255,243,205) in rgb color combination.

Bootstrap alert danger

Alert danger can be created by adding .alert-danger CSS
<div class="alert alert-danger">

Apart from these 4, there are some other classes that can be used for different purposes with alerts. Let’s have a look

Bootstrap error message

We can use bootstrap alerts for error messages .alert-warning and .alert-danger can be used to show normal and critical error messages.

Bootstrap Alert Links

You can add some matching links with matching foreground and background colors using the .alert-link class.

These links can be used to redirect the user to some detailed information about the alert.

Bootstrap Closing Alerts

In some cases, the user may want to remove the alert ones they have addressed it.

This can be done by using dismissible or closable alerts.

In order to do this you can use the .alert-dismissible class to the alert container.

You also need to add class="close" and data-dismiss="alert" to some link or a button element.

Therefore, when you click on this element the alert box will disappear.

Here’s the code to understand this better:

Observe the ‘aria-label’ and ‘&times’ in the above code. 

These two have an important role in this code. The aria-label= “close” attribute is there to have a better accessibility for the close button.

The ‘&times’ or the (×) is actually a better and more preferable way of indicating the close button instead of using the ‘x’ symbol.

Bootstrap Animated Alerts

The two classes used to add an animated fade effect for when closing the alert messages are .fade and .in.

Bootstrap Close Alerts via data-* Attributes

Another way of creating a dismissible alert is by using the data-dismiss="alert" attribute to any link or button element.

Just like the .alert-dismissible class, this too shall close the alert message using the link/button element.

Bootstrap dismissable alert

Bootstrap alert fade out

Bootstrap Tables-striped, border, hover, responsive

Here we will discuss various ways in which Bootstrap can help the developers to make the tables look perfect on the web pages.

Bootstrap table styles

All Table styles are inherited in bootstrap4.

using CSS classes we can create a simple, striped, bordered table.

Can add the hover effect. easily include colors in rows and columns.

let’s see them one by one

Bootstrap table basic

Let us start with the basic table in bootstrap. Here the design is minimal with light padding and only horizontal dividers.

bootstrap table basic

The class used for the basic table is .table. Here’s a sample code for the same:

Bootstrap table striped

 Bootstrap table striped

To add zebra stripes to your table you can use the .table-striped class. Here’s the sample code

Bootstrap table border

For adding table borders, Bootstrap has provided the .table-bordered class. This will add borders at all sides of the table and cells.

Bootstrap table border

Observer the below code:

Bootstrap table hover

To give a special effect on hover, we can use the .table-hover class. The following code illustrates the same

Sr NoTableExample
1Simple Table Try It
2Striped Table Try It
3Border Table Try It

Bootstrap table condensed

The .table-condensed class will help make a table compact, by cutting cell padding in half.

See the code below for a better understanding

Bootstrap Contextual Classes with table

Contextual classes are special classes that can be used to the color table rows/table cells (<td>).

Bootstrap Contextual Classes with table

Here is a list of contextual classes provided by Bootstrap:

  • .active: To apply the hover color to the table rows or table cell
  • .info: To indicates neutral informative change of action
  • .success: To show a successful or positive action
  • .danger: To show some dangerous (potentially negative) action
  • .warning: Indicates a warning that might need attention

Bootstrap responsive tables

Responsiveness is an indispensable feature of Bootstrap for any web page element.

In the case of tables, responsiveness can be achieved using the .table-responsive class.

This makes the table horizontally scrollable on any device with screen width less than 768px.

However, there is no considerable change in devices with a screen size larger than 768px.

.table class is used with .table-responsive{-sm|-md|-lg|-xl} classed

Following is a sample code for responsive tables in Bootstrap:

Bootstrap 4 table example

Above all, we have seen basic examples of table all are compatible with bootstrap 4.

Let us see one more example

How to show names of students and branches in the table.

Bootstrap table header color

to set table header color use contextual classes as below.

<th class="table-success">
<th class="table-danger">
<th class="table-info">
<th class="table-warning">

Bootstrap table row color

use contextual classes with <tr> it will add color to specified table row.

<tr class="table-success">
<tr class="table-danger">
<tr class="table-info">
<tr class="table-warning">

Bootstrap table without borders

Creating a table without a border is possible with bootstrap. To make a borderless table use class .table-borderless

How to make a table responsive

to make a table responsive use .table class with .table-responsive{-sm|-md|-lg|-xl}.

Bootstrap Images

Here we will study about how what Bootstrap 4 has in store for the image elements of your web pages.

Bootstrap 4 images Shapes

Using Bootstrap, the images can be rendered in the following three shapes:

  • Rounded Corners:
  • Circle
  • Thumbnail

Out of these three, the first two are not supported by IE8 or earlier versions

Bootstrap Rounded Corners images

For rounded corners, you can use the .rounded class with your <img> tag.

For example:

Circle images in bootstrap

Adding the .rounded-circle class to <img> the tag will shape your image into a circle.

For example:

Thumbnail images bootstrap

The thumbnail shape can be achieved using the .img-thumbnail class.

For example:

Bootstrap images responsive

The sizes of the images and screens might not go hand-in-hand more often than you can predict.

We need to have responsive images that can automatically adjust as per the size of the screen.

We can make the images responsive using the class. .img-fluid class with the <img> tag.

Now, the image will, nicely, scale to the parent element.

When using .img-fluid class the display is automatically set to block and max-width to 100%. Similarly, height is set to auto as well.

See the code below for example:

Bootstrap Images Gallery

The image gallery can be created by using Bootstrap’s grid system along with the .thumbnail class.

The code below illustrated the same:

Bootstrap Responsive Embeds

Not only the images but the other embedded media like videos and slideshows can also be made responsive to scale properly on any device.

For this, you need to add the class embed-responsive to any <div> item.

You will also need to add the .embed-responsive-item to your <iframe>, <embed>, <video>, and <object> elements.

What is aspect ratio?

The aspect ratio of any image can be described as the proportional relationship between the image’s width and height.

The most common video aspect ratios we have are 4:3 which was a universal video format of the 20th century and 16:9 that is commonly known for the HD television.

We have two classes for these aspect ratios in Bootstrap:

  • embed-responsive embed-responsive-4by3
  • embed-responsive embed-responsive-16by9

Bootstrap <img> Classes

Bootstrap has the following classes for styling your image elements

  • .rounded: To add rounded corners to the image
  • .rounded-circle: To shapes the image into a circle
  • .img-thumbnail: To shape the image into a thumbnail
  • .img-fluid: To make the image responsive make it scale nicely to the parent element.

Bootstrap center images

Block-level images can be centered using .mx-auto

bootstrap images in a row

How to make images responsive in bootstrap

To make images responsive in bootstrap use .img-fluid class

Bootstrap background image

Showing image in background is very simple

use background-image: url(..) css property with url.

Example of background image is as below

Bootstrap Media Objects

The media objects (like images or videos) on the web page need to be aligned properly to stand out but not completely out of context.

HTML and CSS have their own features to provide the required positioning to the media objects on the webpage.

Bootstrap makes it much easier for the developers to align these media objects as per the content and webpage styling.

With Bootstrap, the media objects can be aligned to the left or to the right of the content.

Such alignments styles are useful for blog comments or tweets where both text and pictures are displayed for multiple users.

Bootstrap Media Example
Fig: Bootstrap Media Example

Basic Bootstrap Media Object

Let’s have a look at a sample code for the Left and right alignment of the media object.

Observer the code followed by the explanation:

Bootstrap Media Left and Right Alignment

Bootstrap Media Left and Right Alignment


  • The <div> element is being used with with the .media class here. This will create a container for media objects to be used.
  • As for the alignment, we use the appropriate class for the required aligning direction Therefore the .media-left class will be used to align the media object (image in this case) to the left and similarly, .media-right class is there to to align it to the right.
  • The class= “media-body” is also used with a container in the code. This is to align the text next to the image.
  • Furthermore, the .media-heading can be used for the headings.

Media bootstrap top, middle or bottom alignment

Not just horizontally, we can also set vertical alignments for the media objects.

There are basically three vertical alignments that we generally use in different containers:

  • Top: Media object aligned at the top corner of the content
  • Bottom: Media object aligned bottom corner of the text content
  • Middle: Media object aligned adjacent to vertically middle of the text content

In Bootstrap, these alignments can be made using respectively the classes align-self-start, align-self-centre and align-self-end.

Media bootstrap top, middle or bottom alignment
Fig: Bootstrap media alignment

Here’s a sample code for the vertical alignment of the media objects

Nested media object bootstrap

You can also have nested media objects using bootstrap.

These are quite common on social websites these days.

For example, the ‘replies to the comment’ options in websites like Facebook, Twitter, Instagram, etc.

Have employed the nested media object style for their media object positioning.

Nested media object bootstrap
Fig: Nested media object bootstrap

Bootstrap Containers- container and container-fluid classes

Here, we will check out the Containers, one of the most basic web page layouts employed by Bootstrap to design the web pages.

But before we move into that, let us first understand what a layout is and how a typical layout is made to come to real-world page.

Bootstrap Responsive Webpage Layout

A webpage layout is basically the template that helps you understand the sizing, positioning, and styling of all its components.

More or less, every layout takes care of the following points:

  • Header: The top part of the webpage. It usually contains your website’s logo or name.
  • Navigation Section: This is the section of the page where all the Navbars are present. These can be normal navigation menus or drop-down carrying sub-menu of the selected menus.
  • Content Section: The content section contains all the necessary stuff for that web page.
  • Footer: The footer section of the web-page generally contains links to official stuff about the website or web application. You can find the links for Privacy Policy, About Us and Available Downloads from this part of the page.

This is the basic layout of any web page you’ll come across. A code below will show you a typical web page using the above-mentioned layout:

Bootstrap Responsive Webpage Layout
Fig: Bootstrap Responsive Webpage Layout

Bootstrap Container

The Bootstrap container layout is one of the most basic layouts for a webpage.

When you’re using the grid-system for your webpage, the Bootstrap Container layout can help you the best.

Above-mentioned we’ll have to choose from fixed-width/ fluid-width, responsive containers that suit best for our webpage vision.

div class container

The code below will illustrate the Bootstrap container’s usage on the web page:

Bootstrap container background color

3bg-successTry It
4bg-dangerTry It
5bg-warningTry It
6bg-infoTry It
7bg-lightTry It
8bg-darkTry It
9bg-whiteTry It

Bootstrap container fluid class

You can also use .container-fluid for using a full-width container that will span the entire width of the viewport.

Your div element should have the class container-fluid

To create the class as container-fluid use this with div as below

Which class in bootstrap make container full width

.container-fluid class in bootstrap make container full width

Difference between container and container fluid

The .container has fixed width for each screen size.

The .container-fluid has full width (100%) for each screen size.

Bootstrap 4 Grid System

The grid system in Bootstrap 4 is built using flexbox. It allows a maximum of 12 columns across the web page.

In case you do not need to use all the 12 columns available, you can group individual columns to get wider columns for your usage.

Bootstrap 4 Grid System
Fig: Bootstrap 4 Grid System
Bootstrap 4 Grid System
Fig: Bootstrap 4 Grid System

Due to the responsiveness of the grid system, the columns get re-arranged automatically as per the screen size of the operating device.

Bootstrap nested columns example

Bootstrap nested columns example
Fig: Nested columns example

Bootstrap Grid Classes

Here’s the list of the classes available for Bootstrap’s grid system:

.col – It is for very small devices that have a screen width of less than 576px

.col-sm– This is for the devices having screen width equal to or greater than 576px

.col-md – The range of medium size devices can use this class. the screen width has to be equal to or greater than 768px)

.col-lg – This class is for the devices that have screen widths equal to or greater than 992px

.col-xl – Used for very large devices that have screen width equal to or greater than 1200px

Sr NoCSS ClassExample
1.col Try It
2.col-sm Try It
3.col-md Try It
4.col-lg Try It
5.col-xl Try It

For more creating more dynamic and flexible layouts, the above-listed classes can be combined appropriately.

Please note that since each class scales up, so if you want to set the same width for md as for sm, you just have to specify the above-listed.

Bootstrap column classes basic structure

Take a look at the basic structure of the Bootstrap 4 grid:

Explanation for the First example:  Here we are creating a row (<div class="row">).

Then we added the required columns using suitable .col-*-* classes.

Here the first star (*) tells you the responsiveness i.e. sm, md, lg or xl, the second star, furthermore, represents a number.

This number should ad upto 12 for any given row.

Explanation for Second example: In the second example, instead of adding a number to each col we will let the layout be handled by the bootstrap.

Thus, for equal width columns we have: two “col” elements = 50% width each and three cols = 33.33% width each and so on.

The responsiveness of the columns can be set as per the requirements.

Here are some more examples for different column requirements:

Bootstrap grid examples

Bootstrap 12 column grid

Bootstrap 12 column grid
Fig: Bootstrap 12 column grid

Bootstrap Grid Three Equal Columns

Bootstrap Grid Responsive Columns

The following example will demonstrate, how you can create four equal-width columns.

These will start at tablets and will then scale to extra-large desktop screens.

Responsive columns can be used with devices whose screens width are less than 576px like mobile, the above columns will get stacked on top of each other, automatically.

Bootstrap two column Unequal Responsive Grid

Another example with columns scaling from the tablet screens to extra-large desktop screens. Furthermore, the columns here, will have varied width.

Thus, depending on the requirement, you can use the Bootstrap grid system to provide responsive columns for different devices.

How to put divs next to each other

Bootstrap column resolves this problem.

create a new row and inside row create columns

Bootstrap offset left Example

To create offset we use class offset-*-*.

for small devices it is offset-sm-1

Bootstrap offset left Example
Fig: Bootstrap offset left Example

Bootstrap columns not side by side

To create columns we use .col class these .col must be inside .row class otherwise it will not show columns side by side

The correct way to place .col is as below

Bootstrap padding/margin between columns

offset-* can be used to provide space between columns

Bootstrap padding/margin between rows

bootstreap4 uses following properties for margin and padding

m- for margin
p- for padding

it is used with

t- set margin-top or padding-top
b-set margin-bottom or padding-bottom

with size property

0- margin and padding set to 0
1- margin and padding set to 1

Definition of circle Circumference, Area, Chord, Segment

Definition of circle

When a line AB rotate by 360 degree taking center A, thus obtained figure is called circle.

A is called center of circle. A to any point on the circle joining is called radius, a line passing through the center of the circle is called diameter of circle and its value is 2 * radius.

The ratio between circumference to diameter is always constant and denoted by \pi its value is \frac{22}{7} or 3.14 approximately.


\frac{pI}/D= \pi

Circumference of circle

so circumference of circle (p)=\pi*D=2*\pi*r

Area of circle formula

Area of circle=\pi*r^2=pi*\frac{d^2}{4}

We divide a circle in to many small sectors, thus the length of an arc is reached near about the length of chord.

Then merge them as below we have obtained a ractangle.

Length of Chord

Length of chord=\frac{a^2+h^2}{2h}
where 2a=lengh of chord
h= height of arc
r=radius of circle

length of arc= arc/oce=Angle in degree/360
Radion: If are is equal in length to the radious, then the angle for form are called radion.

Segment of a circle

chord AB of a circle divides the circular region into two part, each part is called a segment of the circle.

Sector of the circle– the area surrounded by an arc and the two radius joining the end point of the arc with the center is called a sector of the circle.

Concentric circle– two or more circles with the given centre are called concentric circle.
