It’s designed to ease the web development process of responsive, mobile-first websites by providing a collection of syntax for template designs. Responsive websites are pages that easily adapt to different devices, platforms, and screen sizes. It is a front-end framework that helps developers create faster and better looking websites. The framework has a collection of HTML, CSS, and JavaScript components that can be easily customized.

And you want to create responsive layouts that display elements like buttons and forms consistently, no matter what device or browser the visitor is using. As with so many open-source projects, Bootstrap has a large community of designers and developers behind it. Being hosted on GitHub makes it easy for developers to modify and contribute to Bootstrap’s codebase. It also makes it easy for people to collaborate, lend their advice, and interact with peers and fellow users. The Bootstrap framework is flexible and robust enough to accommodate almost every need for front-end website development. Its best feature is the design templates that make web pages work optimally on all screen sizes.
For this tutorial, our main CSS file will be bootstrap.css, and we must include that in all our HTML pages. Bootstrap.min.css is just the minified version of bootstrap.css.

When using the grid system, for example, in order to make a column that takes up a third of the screen, you have to add the .col-md-4 class to what is bootstrap it. Explanations also include code samples for basic implementation, simplifying the process for even the most beginner of beginners.
