<p class="lead">Bootstrap is a free collection of tools for creating websites and web applications. It contains HTML and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions. It is the No.1 project on GitHub with 65,000+ stars and 23,800 forks (as of March 2014) [1] and has been used by NASA and MSNBC, among many others..</p>
