### 字体图标:
字体图标是在 Web 项目中使用的图标字体。字体图标在下载的Bootstrap的fonts文件夹中。
~~~
.glyphicon {
position: relative;
top: 1px;
display: inline-block;
font-family: 'Glyphicons Halflings';
-webkit-font-smoothing: antialiased;
font-style: normal;
font-weight: normal;
line-height: 1;
-moz-osx-font-smoothing: grayscale;
}
~~~
.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。关于-webkit-font-smoothing和-moz-osx-font-smoothing:-webkit-font-smoothing属性。这个属性可以使页面上的字体抗锯齿,使用后字体看起来会更清晰舒服。none ------ 对低像素的文本比较好 subpixel-antialiased ------默认值 antialiased ------抗锯齿很好 autoinherit ------继承父元素initial
-moz-osx-font-smoothing属性,其中-osx-表明这是mozilla难得的给特定操作系统推出的特性增强,由于缺乏文档,
目前已知的取值是:
grayscale ------抗锯齿很好
auto ------默认值
inherit
------继承
Bootstrap提供了200个字体图标,每个图标对应一个class,在使用时,我们只需要包含glyphicon和
对应的class即可。
使用方法:
~~~
<!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<title>demo</title>
<link href="bootstrap-3.3.4-dist/css/bootstrap.min.css" rel="stylesheet">
<style type="text/css">
body{padding: 20px;}
</style>
</head>
<body>
<span class = "glyphicon glyphicon-lock"></span>
<span class = "glyphicon glyphicon-lock" style = "font-size:30px;"></span>
<span class = "glyphicon glyphicon-lock" style = "font-size:60px;"></span>
</body>
</html>
~~~

配合button使用:
~~~
<body>
<button class="btn btn-default">
<span class = "glyphicon glyphicon-home"></span>
</button>
<button class="btn btn-success">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-info">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-warning">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-warning btn-lg">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-warning btn-sm">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
</body>
~~~
效果:

### 定制字体图标
在上一个例中,其实我们已经实现了对字体图标大小和颜色的定制,此处再做进一步说明。
通过改变字体的大小或button的大小,可以改变字体图标的大小。
通过设置color的颜色,可以改变字体图标的颜色,如下:
~~~
<body>
<button class="btn btn-success">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-success" style="color:#FF0000;">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-success">
<span class = "glyphicon glyphicon-home" style="color:#FF0000;"></span> Home
</button>
</body>
~~~
效果:

可以看出:通过改变其父元素或者是span本身的color,都可以改变字体图标的颜色。
###
### 应用文本阴影
~~~
<body>
<button class="btn btn-success">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-success btn-lg" style="text-shadow: black 3px 2px 3px;">
<span class = "glyphicon glyphicon-home"></span> Home
</button>
<button class="btn btn-success btn-lg">
<span class = "glyphicon glyphicon-home" style="text-shadow: black 3px 2px 3px;"></span> Home
</button>
</body>
~~~
