查看“MediaWiki目录悬浮+隐藏”的源代码



先进入到下面页面（也许你需要将localhost替换成其他的）：

 http://localhost/mediawiki/index.php/MediaWiki:Common.css
在此页你可以设置全局的css样式，在这里加入如下：

 #toc{
 display: block;
 position: fixed;
 top: 100px;
 right: 0px;
 min-width: 100px;
 max-width: 350px;
 max-height: 20px;
 overflow-y: scroll;
 border: 1px solid #aaa;
 border-radius: 0 0 1px 1px;
 -moz-border-radius: 0 0 1px 1px;
 background: rgba(249,249,249,0.75);
 padding: 12px;
 box-shadow: 0 1px 8px #000;
 -webkit-box-shadow: 0 1px 8px #000;
 -moz-box-shadow: 0 1px 8px #000;
 }
  
 #toc:hover{
 display: block;
 position: fixed;
 top: 100px;
 right: 0px;
 min-width: 100px;
 max-width: 350px;
 max-height: 500px;
 overflow-y: scroll;
 border: 1px solid #aaa;
 border-radius: 0 0 1px 1px;
 -moz-border-radius: 0 0 1px 1px;
 background: rgba(249,249,249,0.75);
 padding: 12px;
 box-shadow: 0 1px 8px #000;
 -webkit-box-shadow: 0 1px 8px #000;
 -moz-box-shadow: 0 1px 8px #000;
 }
 
 body { overflow-x: hidden;}
保存，清除浏览器缓存



关键点解释

 top: 100px;　　目录框到顶部距离
 right: 0px;　　   目录框到右边框距离
 min-width: 100px;　　目录框最小宽度
 max-width: 350px;　　目录框最大宽度
 max-height: 500px;　　目录框最大高度
 background: rgba(249,249,249,0.75);　　背景色和透明度
