In this video, I'll cover how to make a responsive design layout with Bootstrap 3 (from Twitter's development team). This bootstrap tutorial will help you make a responsive HTML & CSS web page that looks great on mobile, tablet, and desktop devices.
Begin by going to http://www.getbootstrap.com and adding bootstrap to your page by copying and pasting the CDN links. Once you have bootstrap added, you can create a 3-column responsive HTML layout within seconds.
Twitter Bootstrap also makes it easy to create navbars, buttons, panels, and other great features in a matter of moments.
