Bootstrap Framework for Web Development | Learn Web Designing

Bootstrap in Web development?

The well-known HTML, CSS, and JavaScript framework known as Bootstrap is used to create responsive and mobile-friendly websites. The most well-liked HTML, CSS, and JavaScript framework for creating responsive and mobile-friendly websites is called Bootstrap. Utilization and download are both completely free. It is a front-end framework used to make web development simpler and quicker. It offers design templates for typography, forms, buttons, tables, navigation, modals, image carousels, and many other things that are based on HTML and CSS. Plug-ins for JavaScript are also an option. You can easily construct responsive designs thanks to it.

Why do developers use bootstrap for web applications

Bootstrap, the easy-to-use framework for web development with a huge list of ready to use elements give enough reasons to use it. Some of the reasons are given below:

  1. Mobile first approach – Bootstrap 3’s framework uses a mobile-first approach and includes mobile-first styles throughout the entire library rather than in individual files.
  • Browser Support – All widely used browsers are compatible with it. Simple to use; anyone can start using Bootstrap with just a basic understanding of HTML and CSS. Additionally, there is good documentation on the Bootstrap official website.
  • Responsive design –  Bootstrap’s responsive features for Desktops, Tablets and Mobiles makes it a simple and easy to make all device compatible web applications. The fact that it is open source is also a plus.

How to use bootstrap in any project?

In any project we basically use the already defined classes and modules by either downloading them into our web application or by fetching them from CDN

To do so, following are the steps to be followed:

  1. By downloading the bootstrap framework
    • The entire directory files are available to download on the bootstrap official website
    • Now just extract the directory to the root folder of your application such that it becomes bootstrap folder containing all the required bootstrap files
    • Now in all the pages of your website/web application include the links for:

CSS file

bootstrap.min.css in the head section of the HTML code


jquery.min.js, popper.min.js, bootstrap.min.js, in the end of the body section of code

  • By accessing it through CDN

CSS: Copy this stylesheet linkin the the <head> section of HTML file.

<link rel=”stylesheet” href=””rel=”nofollow” integrity=”sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm” crossorigin=”anonymous”>

JS: Copy this stylesheet before the end of the <body> section of HTML file.

<script src=”” integrity=”sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN” crossorigin=”anonymous”></script>

Bootstrap Grid System

Bootstrap is frequently used to create layout and content organisation. Using HTML and CSS to quickly and efficiently generate a consistent layout is a very useful technique in web design. As the device or viewport size rises, the flexible, fluid grid architecture appropriately adjusts up to 12 columns. It has sophisticated mixins for creating more semantic layouts as well as preset classes for quick layout options.

Basically to make a web application responsive, this framework takes a screen as a grid with 12 column on a big screen and depending upon a screen size and the columns are contained in a grid of different sizes on different screens

Grid Classes: The Bootstrap grid system has four classes that can be combined to make more flexible layouts:

  • xs (<576px): For Portrait Mobile Phones.
  • sm (>=576px): For Landscapes phones
  • md (>=768px): For Tablets/Phablets
  • lg (>=992px): For Small-sized Desktops/Laptops
  • xl (>=1200px): For Larger-sized Desktops/Laptops

Components of Grid System:

Container : – In order to encapsulate our grid system and wrap the contents of the site, Bootstrap needs a contained element. Row elements are referred to as “containers” for the column elements, and vice versa for row elements. The section of the article where we discuss columns will help you comprehend it more.

For a responsive fixed width container, use “container,” and for a full width container that fills your viewport’s width, use “container-fluid.”

Rows :- To ensure proper alignment and padding, rows must be positioned inside either a “container” or “container-fluid.” To arrange columns horizontally, we utilise rows.

Container :- You can create grid columns by indicating how many of the twelve available columns you want to span. For instance, three “col-sm-4” might be used for three equal columns.

Column Resets :- With the four tiers of grids that are accessible, there will inevitably be problems where, at some breakpoints, one column doesn’t exactly clear right because it has more text than the other. There is a command called clearfix that resolves any difficulties with that viewport. After the block where the column isn’t clearing correctly, we simply need to create a div command with the class clearfix.

Say there is a problem with the md and sm viewport. However, if we’re using

 it is then creating issues for other viewports (perhaps LG and XS). Therefore, we may either hide all other blocks or limit clearfix visibility to the md and sm block (lg and xs).

Columns Offset: Bootstrap allows movement of columns to the right by x columns using  col-<grid-type>-offset-x in the class.

<div class=”col-xs-3 col-sm-4 col-md-6 col-lg-1 col-lg-offset-2“>

Nesting Columns: For nesting columns within a column, we need to add a new row and set of columns. Nested rows should include a set of columns that add up to 12 or less than that.


Set of icons, fonts or some symbols offered by the bootstrap. The Glyphicon contains set of 260 glyphs is include.

You can utilise Glyphicons which are not free and require permission, although their developer has made them freely accessible for Bootstrap projects.
