今天学习了CSS3动画，涉及到的属性：@keyframes,animation,animation-duration,animation-name,animation-timing-function,
animation-delay,animation-iteration-count,animation-direction
上图：（为了对于块元素更明确，我们选用各种强烈对比的颜色）
先上html代码：（非常的简单，就是定义了一个无序列表，但要主要的是再简单的界面，都要作为块级元素，这里就定义了2个div）
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<link href="css/dots.css" rel="stylesheet">
</head>
<body>
<div class="about">
<ul>
<div id="fountainG">
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
</div>
</ul>
</div>
</body>
</html>
下面上css3代码：
ul, li { list-style-type: none }
.about { width: 100%; background: #aaa; padding: 20px 0; overflow: hidden }
.about ul { width: 1000px; margin: auto; line-height: 24px ;background:#bbb;}
#fountainG { position: relative; width: 240px; height: 29px;background:#ccc; }
/*这个是每个点的自己的块*/
#fountainG li { background:#ddd;position: absolute; top: 0; width: 29px; height: 29px;
-moz-animation: bounce_fountainG 3s linear infinite; -moz-transform: scale(.3);
-moz-border-radius: 19px;
-webkit-animation: bounce_fountainG 1.2s linear infinite;
-webkit-transform: scale(.3); -webkit-border-radius: 19px;
-ms-animation: bounce_fountainG 1.2s linear infinite;
-ms-transform: scale(.3); -ms-border-radius: 19px;
-o-animation: bounce_fountainG 1.2s linear infinite;
-o-transform: scale(.3); -o-border-radius: 19px;
animation: bounce_fountainG 1.2s linear infinite;
transform: scale(.3); border-radius: 19px; }
#fountainG li:first-child { left: 0; -moz-animation-delay: 0.48s; -webkit-animation-delay: 0.48s;
-ms-animation-delay: 0.48s; -o-animation-delay: 0.48s; animation-delay: .48s; }
#fountainG li:nth-child(2) { left: 30px; -moz-animation-delay: 0.6s;
-webkit-animation-delay: 0.6s; -ms-animation-delay: 0.6s; -o-animation-delay: 0.6s; animation-delay: 0.6s; }
#fountainG li:nth-child(3) { left: 60px; -moz-animation-delay: 0.72s;
-webkit-animation-delay: 0.72s; -ms-animation-delay: 0.72s; -o-animation-delay: 0.72s; animation-delay: 0.72s; }
#fountainG li:nth-child(4) { left: 90px; -moz-animation-delay: 0.84s;
-webkit-animation-delay: 0.84s; -ms-animation-delay: 0.84s; -o-animation-delay: 0.84s; animation-delay: 0.84s; }
#fountainG li:nth-child(5) { left: 120px; -moz-animation-delay: 0.96s;
-webkit-animation-delay: 0.96s; -ms-animation-delay: 0.96s; -o-animation-delay: 0.96s; animation-delay: 0.96s; }
#fountainG li:nth-child(6) { left: 150px; -moz-animation-delay: 1.08s;
-webkit-animation-delay: 1.08s; -ms-animation-delay: 1.08s; -o-animation-delay: 1.08s; animation-delay: 1.08s; }
#fountainG li:nth-child(7) { left: 180px; -moz-animation-delay: 1.2s;
-webkit-animation-delay: 1.2s; -ms-animation-delay: 1.2s; -o-animation-delay: 1.2s; animation-delay: 1.2s; }
#fountainG li:nth-child(8) { left: 210px; -moz-animation-delay: 1.32s;
-webkit-animation-delay: 1.32s; -ms-animation-delay: 1.32s; -o-animation-delay: 1.32s; animation-delay: 1.32s; }
/*这里是定义动画函数，很简单就是从1倍减小到0.3倍。*/
@-moz-keyframes bounce_fountainG { 0% {
-moz-transform:scale(1);
background-color:#238d7b;
}
100% {
-moz-transform:scale(.3);
background-color:#FFFFFF;
}
}
@-webkit-keyframes bounce_fountainG { 0% {
-webkit-transform:scale(1);
background-color:#238d7b;
}
100% {
-webkit-transform:scale(.3);
background-color:#FFFFFF;
}
}
@-ms-keyframes bounce_fountainG { 0% {
-ms-transform:scale(1);
background-color:#238d7b;
}
100% {
-ms-transform:scale(.3);
background-color:#FFFFFF;
}
}
@-o-keyframes bounce_fountainG { 0% {
-o-transform:scale(1);
background-color:#238d7b;
}
100% {
-o-transform:scale(.3);
background-color:#FFFFFF;
}
}
@keyframes bounce_fountainG { 0% {
transform:scale(1);
background-color:#238d7b;
}
100% {
transform:scale(.3);
background-color:#bbb;
}
}
为了更清楚的看清出块级之间的关系，截一张无动画效果的图片：（初始状态是.3）
