    溫馨提示:易賢網(wǎng)小編為您整理了“CSS3動(dòng)態(tài)效果學(xué)習(xí)筆記”,方便廣大網(wǎng)友查閱!

    @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(zhǎng)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

    例子

    代碼如下
