Bootstrap中包含了丰富的Web组件，根据这些组件，可以快速的搭建一个漂亮、功能完备的网站。其中包括以下组件：
下拉菜单、按钮组、按钮下拉菜单、导航、导航条、路径导航、分页、排版、缩略图、警告对话框、进度条、媒体对象等 Bootstrap，来自
Twitter，是目前很受欢迎的前端框架。Bootstrap 是基于 HTML、CSS、JAVASCRIPT 的，它简洁灵活，使得 Web
开发更加快捷。它由Twitter的设计师Mark Otto和Jacob
Thornton合作开发，是一个CSS/HTML框架。Bootstrap提供了优雅的HTML和CSS规范，它即是由动态CSS语言Less写成。Bootstrap一经推出后颇受欢迎，一直是GitHub上的热门开源项目，包括NASA的MSNBC（微软全国广播公司）的Breaking
News都使用了该项目。[2]
国内一些移动开发者较为熟悉的框架，如WeX5前端开源框架等，也是基于Bootstrap源码进行性能优化而来。Bootstrap是基于HTML5和CSS3开发的，它在jQuery的基础上进行了更为个性化和人性化的完善，形成一套自己独有的网站风格，并兼容大部分jQuery插件。
