Before Bootstrap’s release, it was necessary to import a variety of libraries into your project that offered different components and features for web interface development. Plus with the increased popularity of smartphones there were lack of libraries that could handle the responsiveness of a web page. Bootstrap‘s existence let it quickly become famous as a front-end framework that offered a wide set of tools from page grid up to components that render a web page in the best possible way for any device.

This is presented by creating a beautiful Landing page sample. You will also learn how to create a web application like Twitter by using the full set of components offered in the framework. Finally, you will learn to create a dashboard web app, using Bootstrap to its finest potential including component customizations, event handling, and external library integration. All these examples are explained step-by-step and in depth, while covering the versions 3 and the most recent version 4 of Bootstrap.

By the end of this book, you will be familiar with the development of a plugin for the framework and Bootstrap’s world which is popular for fast paced front-end web development, used in countless projects all over the world, and now yours.
