CSS3動(dòng)畫的轉(zhuǎn)場(chǎng)時(shí)長
CSS3的animation-duration屬性詳解:
此屬性用於設(shè)定animation動(dòng)畫的過渡時(shí)長。
更多關(guān)於animation屬性內(nèi)容可以參考CSS3的animation屬性用法詳解一章節(jié)。?
語法結(jié)構(gòu):
animation-duration：<time> [ ,<time>]*
參數(shù)解析:
time：規(guī)定動(dòng)畫執(zhí)行的時(shí)長，單位是秒（s）。
特別說明:
如果提供多個(gè)屬性值，以逗號(hào)進(jìn)行分隔。?
對(duì)應(yīng)的腳本特性為animationDuration。
