当引入后，您可以使用<i>标签将字体图标放在任何位置。以下一些实用的示例方便你使用。
以下示例保持简单，并假设使用Font Awesome CDN，它提供了自动辅助功能支持。如果您没有使用字体Awesome CDN，请参阅手册辅助功能示例，并阅读更多关于如何让您的图标对所有用户都更出色的信息
基本图标示例 fa-camera-retro
您可以使用CSS前缀fa和图标名称将字体图标放置在任何地方。Font
Awesome设计用于内联元素（为了简洁起见，我们喜欢<i>标签，但使用<span>在语义上更正确）。
<i class="fa fa-camera-retro"></i> fa-camera-retro
fa-lg
fa-2x
fa-3x
fa-4x
fa-5x
要相对于其容器增加图标大小，请使用fa-lg（增加33%）、fa-2x,
fa-3x, fa-4x, or fa-5x类。
<i class="fa fa-camera-retro fa-lg"></i> fa-lg
<i class="fa fa-camera-retro fa-2x"></i> fa-2x
<i class="fa fa-camera-retro fa-3x"></i> fa-3x
<i class="fa fa-camera-retro fa-4x"></i> fa-4x
<i class="fa fa-camera-retro fa-5x"></i> fa-5x
使用fa-fw将图标设置为固定宽度。当不同的图标宽度偏离对齐时，非常适合使用。特别适用于导航列表和列表组。
<div class="list-group">
<a class="list-group-item" href="#"><i class="fa fa-home fa-fw" aria-hidden="true"></i> Home</a>
<a class="list-group-item" href="#"><i class="fa fa-book fa-fw" aria-hidden="true"></i> Library</a>
<a class="list-group-item" href="#"><i class="fa fa-pencil fa-fw" aria-hidden="true"></i> Applications</a>
<a class="list-group-item" href="#"><i class="fa fa-cog fa-fw" aria-hidden="true"></i> Settings</a>
</div>
Use fa-ul and fa-li to easily replace default bullets in unordered
lists.
<ul class="fa-ul">
<li><i class="fa-li fa fa-check-square"></i>List icons</li>
<li><i class="fa-li fa fa-check-square"></i>can be used</li>
<li><i class="fa-li fa fa-spinner fa-spin"></i>as bullets</li>
<li><i class="fa-li fa fa-square"></i>in lists</li>
</ul>
…tomorrow we will run faster, stretch out our arms farther… And then one fine morning— So we beat on, boats against the current, borne back ceaselessly into the past.
Use fa-border and fa-pull-right or fa-pull-left for
easy pull quotes or
article icons.
<i class="fa fa-quote-left fa-3x fa-pull-left fa-border" aria-hidden="true"></i>
...tomorrow we will run faster, stretch out our arms farther...
And then one fine morning— So we beat on, boats against the
current, borne back ceaselessly into the past.

Use the fa-spin class to get any icon to rotate, and use fa-pulse
to have it rotate
with 8 steps. Works well with fa-spinner, fa-refresh, and
fa-cog.
<i class="fa fa-spinner fa-spin fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
<i class="fa fa-circle-o-notch fa-spin fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
<i class="fa fa-refresh fa-spin fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
<i class="fa fa-cog fa-spin fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
<i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
Note: Some browsers on some platforms have issues with animated icons resulting in a jittery wobbling effect. See issue #671 for examples and possible workarounds.
Note: CSS3 animations aren't supported in IE8 - IE9.
normal
fa-rotate-90
fa-rotate-180
fa-rotate-270
fa-flip-horizontal
fa-flip-vertical
To arbitrarily rotate and flip icons, use the fa-rotate-* and
fa-flip-* classes.
<i class="fa fa-shield"></i> normal<br>
<i class="fa fa-shield fa-rotate-90"></i> fa-rotate-90<br>
<i class="fa fa-shield fa-rotate-180"></i> fa-rotate-180<br>
<i class="fa fa-shield fa-rotate-270"></i> fa-rotate-270<br>
<i class="fa fa-shield fa-flip-horizontal"></i> fa-flip-horizontal<br>
<i class="fa fa-shield fa-flip-vertical"></i> fa-flip-vertical
To stack multiple icons, use the fa-stack class on the parent, the
fa-stack-1x
for the regularly sized icon, and fa-stack-2x for the larger icon.
fa-inverse
can be used as an alternative icon color. You can even throw larger
icon classes on the parent
to get further control of sizing.
<span class="fa-stack fa-lg">
<i class="fa fa-square-o fa-stack-2x"></i>
<i class="fa fa-twitter fa-stack-1x"></i>
</span>
fa-twitter on fa-square-o<br>
<span class="fa-stack fa-lg">
<i class="fa fa-circle fa-stack-2x"></i>
<i class="fa fa-flag fa-stack-1x fa-inverse"></i>
</span>
fa-flag on fa-circle<br>
<span class="fa-stack fa-lg">
<i class="fa fa-square fa-stack-2x"></i>
<i class="fa fa-terminal fa-stack-1x fa-inverse"></i>
</span>
fa-terminal on fa-square<br>
<span class="fa-stack fa-lg">
<i class="fa fa-camera fa-stack-1x"></i>
<i class="fa fa-ban fa-stack-2x text-danger"></i>

With our thoughts on icon accessibility in mind, If an icon only adds some extra decoration or branding, it does not need to be announced to users as they are navigating your site or app aurally. Alternatively, if an icon conveys meaning in your content or interface, ensure that this meaning is also conveyed to assistive technologies through alternative displays or text.
