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。
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。
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。
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。
提示:-webkit-font-smoothing和-moz-osx-font-smoothing属性可以使页面上的字体反锯齿,使用后字体看起来会更清晰舒服。
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";
}
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:
<!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 如何使用字体图标</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" ></script></head><body><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>
</body></html>
结果如下所示:
<!DOCTYPE html>
<html>
<head>
<title>导航栏的字体图标</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Bootstrap -->
<link href="//apps.bdimg.com/libs/bootstrap/3.2.0/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="stylesheet">

padding-left: 50px;
}
</style>
<!--[if lt IE 9]>
<script src="//apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js" rel="external nofollow" ></script>
<![endif]-->

<body>

<a class="navbar-brand" href="#">Project name</a>

<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="//apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js" rel="external nofollow" ></script>

</html>
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:
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>
<button type="button" class="btn btn-primary btn-lg" style="color: rgb(212, 106, 64);">
<span class="glyphicon glyphicon-user"></span> User
</button>
<button type="button" class="btn btn-primary btn-lg" style="text-shadow: black 5px 3px 3px;">
<span class="glyphicon glyphicon-user"></span> User
</button
