我上一篇文章(记一次改字体的辛酸史，解决CDN跨域问题)讲的是我改字体的一个过程，用了@font-face的方式，引用了一整个特殊字体，导致网站加载了整个字体文件，访问变慢，所有内容加起来已经有5MB。于是我在找前端如何优化字体加速访问，然而找到的都是Font-Spider(字蛛)，看了网上各种教程，无一例外全是一模一样的。
昨天我测试字体的时候用过有字库，有字库就是一个典型的webfont，我就在想有没有跟有字库差不多的webfont引用方式，不直接引用整个字体，而是引用需要用到字，终于，我在GitHub上找到了这个15年的项目Fontmin，我直接下载了他的客户端，Fontmin提供了Mac os & Windows客户端。只需要将ttf原字体拖入客户端，输入需要用到的字，即可一键生成字体和css配置。

生成之后，会创建以你原字体名开头的eot，ttf，woff，css文件

由于我源站国内访问并不是很快，我修改了css内容，上传字体到我的腾讯云cos并链接，有两个css，一个是name.css，一个是name-embed.css，以下是我的配置

    @font-face {
        font-family: "f";
        src: url("cdn.elstec.cn/test/f.eot"); /* IE9 */
        src: url("cdn.elstec.cn/test/f.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
        
        url("cdn.elstec.cn/test/f.woff") format("woff"), /* chrome、firefox */
        url("cdn.elstec.cn/test/f.ttf") format("truetype"), /* chrome、firefox、opera、Safari, Android, iOS 4.2+ */
        
        url("cdn.elstec.cn/test/f.svg#f") format("svg"); /* iOS 4.1- */
        font-style: normal;
        font-weight: normal;
    }

以下是embed文件

    @font-face {
        font-family: "f";
        src: url("cdn.elstec.cn/test/f.eot"); /* IE9 */
        src: url("cdn.elstec.cn/test/f.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */

我又上传这两个css到cos，用这两句代码引用

    <link rel="stylesheet" href="https://cdn.elstec.cn/test/f.css" />
    <link rel="stylesheet" href="https://cdn.elstec.cn/test/f-embed.css" />

刷新就看到效果啦。(跨域报错的话，请看我上一篇文章)
