一个博客园代码高亮的方案

1.使用过纯CSS实现，不需要JS权限

2.只针对博客园的TinyMCE编辑器讨论

3.高亮代码。

下面的CSS适配了两种插入代码方式，将下面的代码粘贴到“博客后台-设置-页面定制CSS代码”中即可。

  1 /*代码高亮*/
  2 .syntaxhighlighter .bold {
  3     font-weight:unset !important;
  4 }
  5 .syntaxhighlighter .line {
  6     background-color: rgb(40, 43, 46)!important;
  7 }
  8 .syntaxhighlighter .line.alt2 {
  9     background-color: rgb(40, 43, 46)!important;
 10 }
 11 .syntaxhighlighter .line.alt1 {
