Last year Twitter has open sourced a design platform known as Bootstrap. Since Bootstrap turned one years old, the company decided to celebrate by releasing an update with version 2.1. Twitter has thanked the Bootstrap community for making it the most popular project on GitHub. Bootstrap reached that status only a few months after it was launched. The Bootstrap team has updated the platform with new features and bug fixes to the code. Organizations as large as NASA and The White House use Bootstrap to create new products and services. You can see a list of new features on the Bootstrap blog.
