Step by step how to use the Contextual Helper classes of the Twitter Bootstrap 3

        By Carmel Schvartzman

In this tutorial we'll learn how to use the Contextual Helper classes of the Twitter Bootstrap 3. The Bootstrap includes many components for you to import to your web page with a minimal effort and with maximal responsiveness and well design, which can be displayed on a responsive grid system that scales up to 12 <div>s columns, and adapts itself to the device when size decreases.
Bootstrap is the more widely used and more popular CSS3 open source framework for developing responsive web apps,  making front-end web design very fast and easy.

We suppose here that you have already installed the Twitter Bootstrap in your MVC app. If you don't, learn  in this tutorial how to install it in just 2 minutes.

In just 5 minutes we'll build a responsive web page using the  Contextual Helper classes and the Badge of the Twitter Bootstrap , with no effort at all:

The Twitter Bootstrap can be reached & downloaded from the Bootstrap official site : Bootstrap :

That's all!!  In this tutorial we've learned how to use the Contextual Helper classes of the Twitter Bootstrap 3. There are more components, and there will be many more in the future. This tutorial does not intends to survey all components, but give you the tools for you to continue exploring them on your own.
Happy programming.....
