CSS3支持使用自定义字体模块,具体语法如下

@font-face {
  font-family: <YourWebFontName>;
  src: <source> [<format>][,<source> [<format>]]*;
  [font-weight: <weight>];
  [font-style: <style>];
}
h1 {
  font-family: <YourWebFontName>;
}

是不是很简单.Google也开源了一套字体图标文件,Material design icons,字体使用Apache License Version 2.0协议.

@font-face {
  font-family: 'Material Icons';
  font-style: normal;
  font-weight: 400;
  src: url(https://example.com/MaterialIcons-Regular.eot); /* For IE6-8 */
  src: local('Material Icons'),
  local('MaterialIcons-Regular'),
  url(https://example.com/MaterialIcons-Regular.woff2) format('woff2'),
  url(https://example.com/MaterialIcons-Regular.woff) format('woff'),
  url(https://example.com/MaterialIcons-Regular.ttf) format('truetype');
}
.material-icons {
  font-family: 'Material Icons';
  font-weight: normal;
  font-style: normal;
  font-size: 24px;  /* Preferred icon size */
  display: inline-block;
  line-height: 1;
  text-transform: none;
  letter-spacing: normal;
  word-wrap: normal;
  white-space: nowrap;
  direction: ltr;

  /* Support for all WebKit browsers. */
  -webkit-font-smoothing: antialiased;
  /* Support for Safari and Chrome. */
  text-rendering: optimizeLegibility;

  /* Support for Firefox. */
  -moz-osx-font-smoothing: grayscale;

  /* Support for IE. */
  font-feature-settings: 'liga';
}

在需要的地方使用:

<i class="material-icons">face</i>
<!-- 或者 -->
<i class="material-icons">&#xE87C;</i>

你可以向操作普通字体一样,设置图标,宽度高度,行距.项目介绍:http://google.github.io/material-design-icons/,查看所有图标:https://material.io/icons/
