What is Bootstrap ?

Bootstrap is a front-end framework for HTML, CSS and JavaScript that is notable for developing mobile-first and responsive websites. With some basic knowledge of HTML and CSS, you can create Bootstrap forms, tables, buttons, typography, navigation, modals, image carousels and optional JavaScript plugins, by using the premade templates Bootstrap provides you.

All the CSS classes and JavaScript code needed are included in the Bootstrap package.

For example, using the class btn with link (<a class='btn'></a>) elements will make them appear like a button.

Additionally, using the btn-primary class with a link will make it a dark blue button.

Origin of Bootstrap

Bootstrap was developed in 2011.

Bootstrap 1.0.0 was launched in 2011 with only CSS and HTML components. There were no JavaScript plugins included in it until Bootstrap 1.3.0.

Bootstrap 2.0.0 was released in 2012. It was a complete rewrite of the Bootstrap library, and also became a responsive framework. Its components were compatible with all kinds of devices?mobiles, tablets and desktops?and lots of new CSS. JavaScript plugins were included in the package.

After 15 major updates, Bootstrap 3 in 2013 was another significant release, becoming a “Mobile First and always responsive” framework.

In the earlier versions of the framework, a responsive website was optional. In the 2013 release, there were changes in the names of the classes and also in the folder structure of the project.

Bootstrap 3 is not backward compatible. We cannot directly migrate to this version by replacing the core CSS and JavaScript files.

Bootstrap has a huge global community of developers who regularly contribute to its code base at GitHub.
