CSS3動(dòng)畫(huà)屬性并不是很多，但重點(diǎn)其實(shí)是你怎樣去運(yùn)用它，從簡(jiǎn)單的hover狀態(tài)或復(fù)雜的小動(dòng)畫(huà)，都可以巧妙的用CSS3動(dòng)畫(huà)屬性來(lái)實(shí)現(xiàn)

今天主要是和大家分享一個(gè)比較有創(chuàng)意、實(shí)用的CSS天氣圖標(biāo)動(dòng)畫(huà)，靜態(tài)的天氣圖標(biāo)看上去是很呆板，若加上動(dòng)畫(huà)，看起來(lái)會(huì)更加真實(shí)生動(dòng)，以下例子就是很好的參考案例。

下面我們來(lái)做一個(gè)會(huì)下雨的天氣圖標(biāo)實(shí)例，過(guò)程其實(shí)很簡(jiǎn)單哦。

STEP1: 整體HTML架構(gòu)

復(fù)制代碼

代碼如下:

STEP2: 用CSS繪制云朵圖標(biāo)
CSS代碼如下
