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.cssbootstrap-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-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>

结果如下所示:

<div class="navbar navbar-fixed-top navbar-inverse" role="navigation"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">Project name</a> </div> <div class="collapse navbar-collapse"> <ul class="nav navbar-nav"> <li class="active"> <a href="#"> <span class="glyphicon glyphicon-home">Home</span></a> </li> <li> <a href="#shop"> <span class="glyphicon glyphicon-shopping-cart">Shop</span></a> </li> <li> <a href="#support"> <span class="glyphicon glyphicon-headphones">Support</span></a> </li> </ul> </div> <!-- /.nav-collapse --> </div> <!-- /.container --> </div> <!-- jQuery (Bootstrap 插件需要引入) --> <script src="https://cdn.bootcss.com/tutorial/list-214.html3.3.1/jquery.min.js"></script> <!-- 包含了所有编译插件 --> <script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>


定制字体图标

我们已经看到如何使用字体图标,接下来我们看看如何定制字体图标。

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>
