Today I mainly use the hover selector. Move the mouse over to see the effect.

One. Ordinary navigation bar

For this ordinary navigation bar, the color only changes when the mouse slides over it, so the idea becomes very simple.

(1) Use ul tag layout

(2) Mouse passing event

(2) Bracket navigation bar

I won’t say much about the layout of the navigation bar here. You can see that brackets will appear from the text when the mouse passes over it. Idea:

(1) When there is no mouse passing event, the brackets are actually there, but they are invisible in the middle of the text

(2) When the mouse passes over, the brackets move from the middle to both sides, and change from invisible to displayed.

Three. Sliding navigation bar

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
