What is Bootstrap and Why you should use it in Web Development

In web development world, the question What is Bootstrap is quite popular. You may have tried to get the answer but failed to get a proper one. So I decided to provide a proper and easy answer for this question in this article.

The article is updated with the features of Bootstrap version 4.0.

What is Bootstrap

Bootstrap is the most popular, free and open-source framework for creating responsive layout in web pages, with much less efforts. It contains HTML, CSS and JS components for creating forms, buttons, navigation, dropdown, modals, layout and many other things, the list is very long indeed. You can create all these without much efforts, which otherwise would require a lot of CSS, HTML and JS code. If you are a web developer then Bootstrap is for you.

Bootstrap Takes Care of CSS Media Queries

Before Bootstrap, web designers like you had to work on CSS Media Queries to create a responsive web design. Bootstrap simplified this by taking care of Media Queries by its own. This removed the complexity and made it fast and easy.

Please check the article on CSS Media Queries to get more information on this topic.

The first version of Bootstrap was released on August 19, 2011 by a team of Twitter developers. The main idea was to encourage consistency during web development of projects. This consistency was lacking before that time as various libraries were used during web development. This was also leading to high maintenance cost and burden.

Bootstrap solved that inconsistency problem and became an instant hit. Today millions of websites are using it.

Bootstrap can be downloaded from here.

Bootstrap Advantages

Web designers and developers love to use Bootstrap in their projects. They use it to create a responsive web design that looks perfectly accurate on all screen sizes (smartphones, tablets, laptops and PCs).

If you are a web developer then you should look into the advantages that Bootstrap provides:

  • Saves you time – Quickly create features using predefined classes and design templates that are provided by bootstrap.
  • Responsive Design – With Bootstrap you don’t need to apply media queries in your CSS file. It does the adjustment of web page dynamically on all screen sizes.
  • Compatible with all browsers – You don’t have to worry about any browser as it is compatible with latest versions of all browsers – Google Chrome, Firefox, Opera, Safari and Edge.
  • Easy and Simple – It is very easy and simple to use in web designing. If you have basic knowledge of HTML and CSS then you should go ahead with it.
  • Consistency – It gives you the consistency between your projects and other developers.
  • Free and Open Source – There is no restriction at all. Bootstrap is available on GitHub where developers can contribute their efforts.

Bootstrap Structure

Talking about the structure of Bootstrap – It is made up of 2 main parts. These are:

  • 1. bootstrap.css – It contains the global settings, fundamental HTML elements styled with classes, and an advanced grid system. After downloading bootstrap go inside the dist > css where you will find this file. There are two versions of this file bootstrap.css and bootstrap.min.css (minified version) and can use any one of these. Add a reference to this file in the page head area of your web page and before the reference of other stylesheets of your website.
  • 2. bootstrap.js – It contains the JavaScript / jQuery framework of bootstrap. Find it inside the dist > js folder. Add a reference to it just before the <body/> tag in your webpage. Since it requires jQuery to run therefore give the reference of jQuery file in your web page too.
Bootstrap provides many reusable components for iconography, dropdowns, input groups, navigation, alerts, and much more.

How to Use Bootstrap in Website

In order to use bootstrap you have to add ‘bootstrap.css’ and ‘bootstrap.js’ in your website. The below image illustrates this.

Now reference the bootstrap.css in page head (before your site’s CSS files).

    <title>Bootstrap</title>

    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <!-- Bootstrap core CSS -->
    <link href="css/bootstrap.css" rel="stylesheet">

    <!-- Custom style for your website -->
    <link href="style.css" rel="stylesheet">
Make sure to add the viewport in the page head too.

In the body tag and just before the end (i.e. Just before the </body> tag), add the reference to the jQuery and then add reference to Popper.js followed by bootstrap core JavaScript file bootstrap.js file.

<body>
    <!--Your web page HTML-->

    <!--Reference to jQuery-->
    <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

    <!--Reference to Popper.js--> 
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
    
    <!--Reference to Bootstrap core JavaScript-->
    <script src="js/bootstrap.js"></script>
</body>
</html>
I have given the reference of ‘Popper JS’ from Cloudflare CDN so I don’t have to download and keep this JS file on my website folder.
