前言

平時我們在瀏覽網(wǎng)頁時，如下圖的導(dǎo)航欄已經(jīng)屢見不鮮了，當(dāng)鼠標(biāo)放上去時，右側(cè)隱藏的內(nèi)容就會慢慢平滑展開，非常美觀且實用，那你知道這種效果是怎么實現(xiàn)的嗎？下面我們就一起實踐一下。

如圖所示：

實現(xiàn)思路

首先我們需要把所有的導(dǎo)航欄通過 fixed 屬性定位到網(wǎng)頁的右下角；
設(shè)置 transition 屬性將所有導(dǎo)航欄添加平滑的過渡效果；
利用 right 屬性將所有導(dǎo)航欄向右偏移；
當(dāng)鼠標(biāo)觸摸某一個導(dǎo)航欄時，運用 hover 屬性，將 right 的值設(shè)置為 0px，配合之前說到的 transition 屬性讓其右側(cè)內(nèi)容平滑的展示出來即可。

話不多說，下面直接看源碼

拓展延伸

當(dāng)然，上面實現(xiàn)的操作只是一種展現(xiàn)形式，類似的功能在效果上可能大相徑庭，接下來帶大家一起看看下面這幾個案例實現(xiàn)的效果。
