이 평범한 네비게이션 바의 경우, 마우스가 위로 슬라이드될 때만 색상이 바뀌므로 아이디어가 매우 간단해집니다.

(1) ul 태그 레이아웃 사용

(2) 마우스 통과 이벤트

여기에서는 탐색 표시줄의 레이아웃에 대해 많이 언급하지 않겠습니다. 마우스를 위에 올리면 텍스트에 괄호가 표시됩니다. 아이디어:

(1) 마우스 통과 이벤트가 없을 때 괄호는 실제로는 있지만 텍스트 중간에 보이지 않습니다

(2) 마우스가 넘어가면 괄호가 가운데에서 양쪽으로 이동하면서 보이지 않는 상태에서 보이는 상태로 변경됩니다.

从演示效果来看要注意两点

（1）鼠标经过时有横向从上到下

（2）鼠标经过时文字从上到下并且变换颜色

这就和上一个例子很像了

（1）横线其实是存在的，只不过鼠标没有经过时是在文字上方且透明的，鼠标经过时横线由上到下。

（2）文字这里就要定义一个动画了，因为在鼠标经过时它体现了三种状态：

　　①文字从现位置划下

　　②文字从出现在上方

　　③文字从上方滑到现位置

这里注意的是不能给标签设置宽高，因为一旦设置宽高会影响文字滑动路线，变得很夸张。这里加span也是这个原因，鼠标经过a时让span以a为参照进行滑动。

里面的标签就不解释了，自己查效果会更好哦。

我好无奈呀，用这个显示效果a标签和li的默认样式竟然不能取消，谁能告诉我为什么/(ㄒoㄒ)/~~ 不过自己编译的话在浏览器里是正常的
