Font Awesome是一种web font，它包含了几乎所有常用的图标，比如Twitter、facebook等等。用户可以自定义这些图标字体，包括大小、颜色、阴影效果以及其它可以通过CSS控制的属性。它有以下的优点：
- 1、像矢量图形一样，可以无限放大
- 2、只需一种字体，同时拥有多个图标，目前支持439个图标
- 3、无需考虑兼容性问题，fontawesome不依赖于javascript
- 4、通过CSS可以任意控制所有图标的大小 ，颜色，阴影。
- 5、由于fontawesome是矢量字体，可以完全兼容视网膜屏
- 6、能和Bootstrap等常用UI框架一起使用，良好兼容性
- 7、可以用于桌面应用中
- 8、不像其它字体那样， 它可以兼容屏幕阅读器。
它的缺点是：
- 1、对IE6等浏览器兼容性不是很好，不过最新版本的Font Awesome和IE7完美兼容
- 2、要想用fontawesome，需要引入相关的字体文件，增加了网页大小
