1.transition属性:
transition-duration: transition效果需要指定多少秒或毫秒才能完成
transition-timing-function: 指定transition效果的转速曲线
transition-delay: 定义transition效果开始的时候
例子:
div
{
width:100px;
height:100px;
background:red;
transition:transform 1s ease 1s;
-webkit-transition:transform 2s ease 1s;
} div:hover
{
transform:translate(200px, 0px);
}
当鼠标移在div上,1s延迟后,div向右以ease方式,在2s内,移动200px。
还有transition属性的分解写法:
<style>
div
{
width:100px;
height:100px;
background:red;
transition-property:width;
transition-duration:2s;
transition-delay:2s;
transition-timing-function: ease; /* Safari/Chrome */
-webkit-transition-property:width;
-webkit-transition-duration:2s;
-webkit-transition-delay:2s;
-webkit-transition-timing-function: ease;
} div:hover
{
width:300px;
}
</style>
注意:
该属性不兼容IE9以及更早版本的浏览器;
该过度效果开始前会停顿2s;
值 | 描述 |
---|---|
linear | 规定以相同速度开始至结束的过渡效果(等于 cubic-bezier(0,0,1,1))。 |
ease | 规定慢速开始,然后变快,然后慢速结束的过渡效果(cubic-bezier(0.25,0.1,0.25,1))。 |
ease-in | 规定以慢速开始的过渡效果(等于 cubic-bezier(0.42,0,1,1))。 |
ease-out | 规定以慢速结束的过渡效果(等于 cubic-bezier(0,0,0.58,1))。 |
ease-in-out | 规定以慢速开始和结束的过渡效果(等于 cubic-bezier(0.42,0,0.58,1))。 |
cubic-bezier(n,n,n,n) | 在 cubic-bezier 函数中定义自己的值。可能的值是 0 至 1 之间的数值。 |
关于这几个速度的例子,看下面:

三、animation
- animation-name
- animation-duration
- animation-timing-function
- animation-delay
- animation-iteration-count
- animation-direction
animation: name duration timing-function delay iteration-count direction;
animation-name: 规定需要绑定到选择器的 keyframe 名称。
animation-duration: 规定完成动画所花费的时间,以秒或毫秒计。
animation-timing-function: 规定动画的速度曲线。
animation-delay: 规定在动画开始之前的延迟。
animation-iteration-count: 规定动画应该播放的次数。
animation-direction: 规定是否应该轮流反向播放动画。
CSS3 @keyframes 规则
浏览器支持情况:
Internet Explorer 10、Firefox 以及 Opera 支持 @keyframes 规则和 animation 属性。
Chrome 和 Safari 需要前缀 -webkit-。
注释:Internet Explorer 9,以及更早的版本,不支持 @keyframe 规则或 animation 属性。
下面的表格列出了 @keyframes 规则和所有动画属性:
属性 | 描述 | CSS |
---|---|---|
@keyframes | 规定动画。 | 3 |
animation | 所有动画属性的简写属性,除了 animation-play-state 属性。 | 3 |
animation-name | 规定 @keyframes 动画的名称。 | 3 |
animation-duration | 规定动画完成一个周期所花费的秒或毫秒。默认是 0。 | 3 |
animation-timing-function | 规定动画的速度曲线。默认是 "ease"。 | 3 |
animation-delay | 规定动画何时开始。默认是 0。 | 3 |
animation-iteration-count | 规定动画被播放的次数。默认是 1。 infinite 无限; | 3 |
animation-direction | 规定动画是否在下一周期逆向地播放。默认是 "normal"。
alternate 反向播放;
|
3 |
animation-play-state | 规定动画是否正在运行或暂停。默认是 "running"。 | 3 |
animation-fill-mode | 规定对象动画时间之外的状态。 | 3 |

=====================================下面是例子 有些是摘抄的================================================
例子1:头像照片发光:
animations
不仅适用于CSS2中的属性,CSS3也是支持的,例如box-shadow
盒阴影效果,所以,我们可以实现外发光效果的。使用过web qq的人应该有印象,当鼠标移到聊天对象脑袋上的时候会有蓝色外发光的动画,但是那是gif动画图片实现的(现在自动跳转到web qq 2.0已看不到效果)。但是gif的重用性有限而且制作破费功夫,如果简单几行CSS代码就可以实现高性能高扩展的效果岂不更加,现在animations
就可以搞定这一些。

例子2:图片轮转缩放显示动画demo
下面这个实例是与图片位置,比例尺寸挂钩的,聪明的你是不是想到了transform
属性呢。对的,transform
+tranisition
,双剑合璧,天下无敌。下面这个效果是很酷很酷的,以前基本上只能在Flash中可以看到。
<!doctype html>

例子3:选项卡切换
我们平时的选项卡切换基本上都是很生硬的,直接啪啪啪,切换过来了,没有点过渡啊什么的(毕竟写JavaScript动画成本较高),现在,有了transitions
,实现过渡效果就是几行CSS代码的事情,不多说了,直接上实例。
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>平滑选项卡切换demo</title>
<link rel="stylesheet" type="text/css" href="bootstrap/bootstrap.min.css">
<style type="text/css">
.demo {
padding: 10px;
margin: 100px 0 0 100px;
}
.trans_image_box {
width: 1600px;
height: 300px;
-webkit-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-o-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;
}
.trans_box {
width: 400px;
margin: 20px;
overflow: hidden;
}
.trans_image {
width: 400px;
float: left;
}
.trans_image_trigger {
padding-top: 10px;
text-align: center;
}
</style>
</head>
<body>
<div class="demo"> <div class="trans_box">
<div id="transImageBox" class="trans_image_box">
<img class="trans_image" src="data:images/ps1.jpg">
<img class="trans_image" src="data:images/ps2.jpg">
<img class="trans_image" src="data:images/ps3.jpg">
<img class="trans_image" src="data:images/ps4.jpg">
</div>
<div id="transImageTrigger" class="trans_image_trigger">
<a href="#1">图片1</a>
<a href="#2">图片2</a>
<a href="#3">图片3</a>
<a href="#4">图片4</a>
</div>
</div> </div>
</body>
<script src="jquery/jquery.min.js"></script>
<script src="bootstrap/bootstrap.min.js"></script>
<script type="text/javascript">
(function() {
var $ = function(id) {
return document.getElementById(id);
};
var oBox = $("transImageBox"),
oTrigger = $("transImageTrigger").getElementsByTagName("a"),
lTrigger = oTrigger.length; if (oBox && lTrigger) {
for (var i = 0; i<lTrigger; i+=1) {
oTrigger[i].onclick = function() {
var index = Number(this.href.replace(/.*#/g, "")) || 1;
oBox.style.marginLeft = (1 - index) * 400 + "px";
return false;
};
}
}
})();
</script>
</html>
CSS其作用的就是那个值以all
开头的transition
属性;
这里点击控制transImageBox的margin-left,而由于transition对all都有效果,所以改变margin-left也是有动画效果的;
只要是CSS值变换的,只要是额外有transition
属性设置的,都是平滑效果,都是动画。
