MediaWiki目录悬浮+隐藏

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
