bootstrap学习

1..fa-list-ol:after {
  content: "\f0cb";

}------这个是font Awesome(在bootstrap下弄得)自定义的图标，f0cb对应一个图标

Font Awesome is a web font containing all the icons from the Twitter Bootstrap framework, and now many more. Whilst the implementation in Bootstrap is designed to be used with the <i> element (Bootstrap v2), you may find yourself wanting to use these icons on other elements. To do so, you'll need to use the following CSS on the desired element, and then substitute in the content value for the relevant icon.
