## Description
|
||
<section id="description"> Font Awesome是一个方便的图标库。这些图标是矢量图形，以<code>.svg</code>文件格式存储。这些图标就像字体一样对待。您可以使用像素指定其大小，并且它们将采用其父HTML元素的字体大小。您可以在任何应用程序中包含Font Awesome，方法是在HTML的顶部添加以下代码： <code><link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" integrity="sha384-XdYbMnZ/QjLh6iI4ogqCTaIjrFk87ip+ekIjefZch0Y+PvJ8CDYtEs1ipDmPorQ+" crossorigin="anonymous"></code>在这种情况下，我们已经在幕后为您添加了这个页面。 <code>i</code>元素最初用于使其他元素斜体，但现在通常用于图标。您可以将Font Awesome类添加到<code>i</code>元素以将其转换为图标，例如： <code><i class="fa fa-info-circle"></i></code>请注意， <code>span</code>元素也可用于图标。使用Font Awesome将一个<code>thumbs-up</code>图标添加到你喜欢的按钮，给它一个带有<code>fa</code>和<code>fa-thumbs-up</code>类的<code>i</code>元素;确保在图标旁边保留“赞”字样。 </section>
