@keyframe 規(guī)定動畫
一般是跟animation一起用
animation : 規(guī)定動畫的名字 規(guī)定動畫的時間 規(guī)定動畫的速度曲線。
@keyframe 定義動畫的名稱{ 動畫時長的百分比。{一個或多個合法的 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
