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。


@font-face {
  font-family: 'Glyphicons Halflings';
  src: url('../fonts/glyphicons-halflings-regular.eot');
  src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');
}
 
.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;
}

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：

实例

 
<p>
    <button type="button" class="btn btn-default">
        <span class="glyphicon glyphicon-sort-by-attributes"></span>
    </button>
    <button type="button" class="btn btn-default">
        <span class="glyphicon glyphicon-sort-by-attributes-alt"></span>
    </button>
    <button type="button" class="btn btn-default">
        <span class="glyphicon glyphicon-sort-by-order"></span>
    </button>
    <button type="button" class="btn btn-default">
        <span class="glyphicon glyphicon-sort-by-order-alt"></span>
    </button>
</p>
<button type="button" class="btn btn-default btn-lg">
    <span class="glyphicon glyphicon-user"></span> User
</button>
<button type="button" class="btn btn-default btn-sm">
    <span class="glyphicon glyphicon-user"></span> User
</button>
<button type="button" class="btn btn-default btn-xs">
    <span class="glyphicon glyphicon-user"></span> User
</button>
