bootstrap中有icon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。
Bootstrap 捆绑了 200 多种字体格式的字形
小图标icon是一个优秀Web中不可缺少的一部分，起到画龙点睛的效果。在Bootstrap框架中也为大家提供了250多个不同的icon图片。
Bootstrap框架中的图标都是字体图标，其实现原理就是通过@font-face属性加载了字体
@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');
}自定义完字体之后，需要对icon设置一个默认样式，在Bootstrap框架中是通过给元素添加“glyphicon”类名来实现，然后通过伪元素“:before”的“content”属性调取对应的icon编码
.glyphicon {
position: relative;
top: 1px;
display: inline-block;
font-family: 'Glyphicons Halflings';
font-style: normal;
font-weight: normal;
line-height: 1;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
}
.glyphicon-asterisk:before {
content: "\2a";
}Bootstrap部分图标如图所示：

By balancing the use of ID and class, a more robust and efficient CSS architecture can be implemented.
