Bootstrap最初是由@mdo and @fat于2010中旬创造的。在开源之前被称为Twitter Blueprint。经过几个月的开发,Twitter举办了first Hack Week,之后,这个项目被公布出来,不同水平的开发者参与进来,当时还没有任何外部的指导。在开源之前的近一年多的时间里,这个项目作为公司内部工具开发的样式指南,当然,现在它仍然扮演者同样的角色。

Originally released on , we've since had over twenty releases, including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.
