博客园美化教程

最终效果如下，有头像、背景图片、返回顶部、爱心特效、以及代码高亮等

1）页面定制 CSS 代码

/*背景图片*/
/*url里放背景图片地址*/

5）注意

引用网络图片可能会失效，可以先将图片下载到本地，之后上传到博客园，最后在引用博客园图片地址；

代码高亮选择的是SyntaxHighlighter，需要从 https://codeload.github.com/syntaxhighlighter/syntaxhighlighter/zip/3.0.83 下载代码，之后将shCoreRDark.css 和shThemeDefault.css 上传到博客园，之后在后台引用该文件地址即可；

代码高亮在代码中需要设置，首先插入代码，之后编辑html源码，找到代码块的<div class="cnblogs_code"><pre>改成<div class="cnblogs_Highlighter"><pre class="brush:sql;gutter:true;">即可，效果如上面代码块。
