@keyframe 規(guī)定動(dòng)畫

一般是跟animation一起用

animation : 規(guī)定動(dòng)畫的名字 規(guī)定動(dòng)畫的時(shí)間 規(guī)定動(dòng)畫的速度曲線。

@keyframe 定義動(dòng)畫的名稱{ 動(dòng)畫時(shí)長的百分比。{一個(gè)或多個(gè)合法的 CSS 樣式屬性} }

目前大部分瀏覽器都沒有支持@keyframe 和animation;所以要分瀏覽器書寫

@keyframe

1.safari和chrome瀏覽器

@-webkit-keyframes myfrom{

from {top:0;}

to {top:200px;}

}

2.Firefox瀏覽器

@-moz-keyframes myfrom{

from {top:0;}

to {top:200px;}

}

3.Opera瀏覽器

@-o-keyframes myfrom{

from {top:0;}

to {top:200px;}

}

animation

1.safari和chrome瀏覽器

@-webkit-animation : myfrom 5s infinite

2.Firefox瀏覽器

@-moz-animation : myfrom 5s infinite

2.Opera瀏覽器

@-o-animation : myfrom 5s infinite
