Bootstrap 字体图标(Glyphicons)
本章将讲解字体图标(Glyphicons)，并通过一些实例了解它的使用。Bootstrap 捆绑了 200 多种字体格式的字形。首先让我们先来理解一下什么是字体图标。
什么是字体图标？
字体图标是在 Web 项目中使用的图标字体。虽然，Glyphicons Halflings 需要商业许可，但是您可以通过基于项目的 Bootstrap 来免费使用这些图标。
为了表示对图标作者的感谢，希望您在使用时加上 GLYPHICONS 网站的链接。
获取字体图标
我们已经在 环境安装 章节下载了 Bootstrap 3.x 版本，并理解了它的目录结构。在 fonts 文件夹内可以找到字体图标，它包含了下列这些文件：
- glyphicons-halflings-regular.eot
- glyphicons-halflings-regular.svg
- glyphicons-halflings-regular.ttf
- glyphicons-halflings-regular.woff
相关的 CSS 规则写在 dist 文件夹内的 css 文件夹内的 bootstrap.css 和 bootstrap-min.css 文件上。

CSS 规则解释
下面的 CSS 规则构成 glyphicon class。

.glyphicon

display:

; -
webkit-font-smoothing:

;
font-style:
normal
;
font-weight:
normal
;
line-height:
1
; -
moz-osx-font-smoothing:
grayscale
;
}
所以 font-face 规则实际上是在找到 glyphicons 地方声明 font-family 和位置。
.glyphicon class 声明一个从顶部偏移 1px 的相对位置，呈现为 inline-block，声明字体，规定 font-style 和 font-weight 为 normal，设置行高为 1。除此之外，使用 -webkit-font-smoothing: antialiased 和 -moz-osx-font-smoothing: grayscale; 获得跨浏览器的一致性。
然后，这里的
.glyphicon:empty {
width: 1em;
}
是空的 glyphicon。
这里有 200 个 class，每个 class 针对一个图标。这些 class 的常见格式如下：
.glyphicon-keyword:before {
content: "hexvalue";
}
比如，使用的 user 图标，它的 class 如下：
.glyphicon-user:before {
content: "\e008";
}
用法
如需使用图标，只需要简单地使用下面的代码即可。请在图标和文本之间保留适当的空间。
<span class="glyphicon glyphicon-search"></span>
下面的实例演示了如何使用字体图标：

我们将以上面的实例开始，并通过改变字体尺寸、颜色和应用文本阴影来进行定制图标。
下面是开始的代码：
<button type="button" class="btn btn-primary btn-lg"> <span class="glyphicon glyphicon-user"></span> User </button>
效果如下所示：
定制字体尺寸
通过增加或减少图标的字体尺寸，您可以让图标看起来更大或更小。
<button type="button" class="btn btn-primary btn-lg" style="font-size: 60px"> <span class="glyphicon glyphicon-user"></span> User </button>
定制字体颜色
<button type="button" class="btn btn-primary btn-lg" style="color: rgb(212, 106, 64);"> <span class="glyphicon glyphicon-user"></span> User </button>
应用文本阴影
<button type="button" class="btn btn-primary btn-lg" style="text-shadow: black 5px 3px 3px;"> <span class="glyphicon glyphicon-user"></span> User </button>
