• CSS Animation 属性


    一、animation是CSS3中新增的属性,它可以制作出多种酷炫的动画效果,如果对flash有一定的了解,那这个属性就会很容易学习。

    先展示一下简单的动画效果

    二、下面就来了解一下animation的具体属性。

      1.动画名称

    1             /*1.name:动画名称*/
    2             /*-webkit-animation-name: kf_play;*/
    3             /*-moz-animation-name: kf_play;*/
    4             /*-o-animation-name: kf_play;*/
    5             /*animation-name: kf_play;*/

      2.动画的持续时间,即播放一次动画所需的时间

    1             /*2.duration:动画持续时间*/
    2             /*-webkit-animation-duration: 2s;*/
    3             /*-moz-animation-duration: 2s;*/
    4             /*-o-animation-duration: 2s;*/
    5             /*animation-duration: 2s;*/

      3.动画播放速率曲线,这个属性与transition的一样。

    1             /*3.animation-timing-function:动画播放速率曲线*/
    2             /*-webkit-animation-timing-function: linear;*/
    3             /*-moz-animation-timing-function: linear;*/
    4             /*-o-animation-timing-function: linear;*/
    5             /*animation-timing-function: linear;*/
    6             /*其他可选值:ease | linear | ease-in | ease-out | ease-in-out*/

      4.动画延迟时间

    1             /*4.delay:动画延迟*/
    2             /*-webkit-animation-delay: 0s;*/
    3             /*-moz-animation-delay: 0s;*/
    4             /*-o-animation-delay: 0s;*/
    5             /*animation-delay: 0s;*/

      5.动画的播放次数

    1             /*5.animation-iteration-count:动画播放次数*/
    2             /*-webkit-animation-iteration-count: 1;*/
    3             /*-moz-animation-iteration-count: 1;*/
    4             /*-o-animation-iteration-count: 1;*/
    5             /*animation-iteration-count: 1;*/
    6             /*其他可选值:infinite(无限次)*/

      6.动画播放是否反向

    1             /*6.animation-direction:动画时间轴的播放方向*/
    2             /*-webkit-animation-direction: normal;*/
    3             /*-moz-animation-direction: normal;*/
    4             /*-o-animation-direction: normal;*/
    5             /*animation-direction: normal;*/
    6             /*其他可选值:normal(普通) | reverse(反向) | alternate(先正向,后反向) | alternate-reverse(先反向,后正向)*/
    normal
    reverse
    alternate
    alternate-reverse

      

      7.动画播放完之后,画面定格在哪一帧。

    1             /*7.animation-fill-mode:动画播放完毕后,动画定格的动画帧*/
    2             /*-webkit-animation-fill-mode: none;*/
    3             /*-moz-animation-fill-mode: none;*/
    4             /*-o-animation-fill-mode: none;*/
    5             /*animation-fill-mode: none;*/
    6             /*其他可选值: none(无) | forwards(结束帧) | backwards(开始帧) | both(开始帧或结束帧)*/

      8.动画播放的状态(暂停/播放)。

    1             /*8.animation-play-state:动画的播放状态*/
    2             /*-webkit-animation-play-state: running | paused;*/
    3             /*-moz-animation-play-state: running | paused;*/
    4             /*-o-animation-play-state: running | paused;*/
    5             /*animation-play-state: running | paused;*/
    移入鼠标

    三、@keyframes。

       animation不能单独使用,必须配合@keyframes{}。然后使用animation-name关联起来。

     1 <style>
     2     .play-box{
     3             animation-name: kf_play;
     4         }
     5 
     6     @keyframes kf_play {
     7             0% {
     8                 width: 100px;
     9             }
    10             100% {
    11                 width: 300px;
    12             }
    13         }
    14 </style>

      @keyframe 的语法。

      1.可以使用关键词“form”和“to”来表示动画从开始到结束的关键帧。

      2.还可以使用%定义多个关键帧的样式(而%的基值是动画播放时间:animation-duration):

     1 @keyframes kf_play {
     2             0% {
     3                 width: 100px;
     4             }
     5             10% {
     6                 width: 200px;
     7             }
     8             50% {
     9                 width: 300px;
    10             }
    11             80% {
    12                 width: 400px;
    13             }
    14             100% {
    15                 width: 500px;
    16             }
    17         }

    四、最后贴上所有动画的代码:

      1 <!DOCTYPE html>
      2 <html lang="en">
      3 <head>
      4     <meta charset="UTF-8">
      5     <title>title</title>
      6     <style>
      7         .play-box {
      8             width: 200px;
      9             height: 20px;
     10             margin: 5px auto;
     11             background-color: #00ccff;
     12             border: 1px solid #000;
     13             -webkit-animation: kf_play 3s ease infinite alternate;
     14             -o-animation: kf_play 3s ease infinite alternate;
     15             animation: kf_play 3s ease infinite alternate;
     16 
     17             /*--------animation attribute--------*/
     18 
     19             /*1.name:动画名称*/
     20             /*-webkit-animation-name: kf_play;*/
     21             /*-moz-animation-name: kf_play;*/
     22             /*-o-animation-name: kf_play;*/
     23             /*animation-name: kf_play;*/
     24 
     25             /*2.duration:动画持续时间*/
     26             /*-webkit-animation-duration: 2s;*/
     27             /*-moz-animation-duration: 2s;*/
     28             /*-o-animation-duration: 2s;*/
     29             /*animation-duration: 2s;*/
     30 
     31             /*3.animation-timing-function:动画播放速率曲线*/
     32             /*-webkit-animation-timing-function: linear;*/
     33             /*-moz-animation-timing-function: linear;*/
     34             /*-o-animation-timing-function: linear;*/
     35             /*animation-timing-function: linear;*/
     36             /*其他可选值:ease | linear | ease-in | ease-out | ease-in-out*/
     37 
     38             /*4.delay:动画延迟*/
     39             /*-webkit-animation-delay: 0s;*/
     40             /*-moz-animation-delay: 0s;*/
     41             /*-o-animation-delay: 0s;*/
     42             /*animation-delay: 0s;*/
     43 
     44             /*5.animation-iteration-count:动画播放次数*/
     45             /*-webkit-animation-iteration-count: 1;*/
     46             /*-moz-animation-iteration-count: 1;*/
     47             /*-o-animation-iteration-count: 1;*/
     48             /*animation-iteration-count: 1;*/
     49             /*其他可选值:infinite(无限次)*/
     50 
     51             /*6.animation-direction:动画时间轴的播放方向*/
     52             /*-webkit-animation-direction: normal;*/
     53             /*-moz-animation-direction: normal;*/
     54             /*-o-animation-direction: normal;*/
     55             /*animation-direction: normal;*/
     56             /*其他可选值:normal(普通) | reverse(反向) | alternate(先正向,后反向) | alternate-reverse(先反向,后正向)*/
     57 
     58             /*7.animation-fill-mode:动画播放完毕后,动画定格的动画帧*/
     59             /*-webkit-animation-fill-mode: none;*/
     60             /*-moz-animation-fill-mode: none;*/
     61             /*-o-animation-fill-mode: none;*/
     62             /*animation-fill-mode: none;*/
     63             /*其他可选值: none(无) | forwards(结束帧) | backwards(开始帧) | both(开始帧或结束帧)*/
     64 
     65             /*8.animation-play-state:动画的播放状态*/
     66             /*-webkit-animation-play-state: running | paused;*/

     70 
     71             /*--------animation attribute  end--------*/
