在修改主题模板的时候，有个别图标需要调整。找了了一下没发现这些图标的所使用的字体，最后发现字体居然一串Base64字符串。

于是就研究了一下，没想到CSS里面还可以通过Base64直接嵌入字体。之前就了解了不少免费的图标库，因为主体模板里使用的是IcoMoon，这里就以此为例：

• 首先将主题模板中的字体提取出来：
  
  IcoMoon Font

• 提取其中的base64字符串，将其复制到https://www.motobit.com/util/base64-decoder-encoder.asp中，选择decode及export，导出字体源文件base64.bin。
  
• 由CSS中字体的“x-font-ttf”属性可知，这是个ttf字体文件，可直接将base64.bin的扩展名改为base64.ttf，得到该字体文件，这时候就可以使用IcoMoon来编辑图标了。
  进入IcoMoon App：https://icomoon.io/app/，点击Import Icons上传base64.ttf，可以看到字体所带的矢量图标，可进行编辑、移动和删除操作，同时也可以加入IcoMoon图标库中免费的490个图标。
  
• 选中自己需要的图标后，点击Generate Font，可生成矢量图标文件，包含woff、ttf、svg、eot及相对应的css和demo。
  但生成的文件是不包含base64的，这时候就需要用到https://www.css-js.com/tools/base64.html，将图标、字体文件转换为Base64字符串。
  
• 最后将新的Base64替换主体模板原有的Base64就大功告成了！
