昨晚用CSS3实现了几种常见的Loading效果，虽然很简单，但还是分享一下，顺便也当是做做笔记……
第一种效果
代码如下：
<div class="loading">
<span></span>
<span></span>
<span></span>
<span></span>
<span></span>
</div>
.loading{
width: 80px;
height: 40px;
margin: 0 auto;
margin-top:100px;
}
.loading span{
display: inline-block;
width: 8px;
height: 100%;
border-radius: 4px;
background: lightgreen;
-webkit-animation: load 1s ease infinite;
}
@-webkit-keyframes load{
0%,100%{
height: 40px;
background: lightgreen;
}
50%{
height: 70px;
margin: -15px 0;
background: lightblue;
}
}
.loading span:nth-child(2){
-webkit-animation-delay:0.2s;
}
.loading span:nth-child(3){
-webkit-animation-delay:0.4s;
}
.loading span:nth-child(4){
-webkit-animation-delay:0.6s;
}
.loading span:nth-child(5){
-webkit-animation-delay:0.8s;
}
第2种效果：
代码如下：
<div class="loading">
<span></span>
</div>
.loading{
width: 150px;
height: 4px;
border-radius: 2px;
margin: 0 auto;
margin-top:100px;
position: relative;
background: lightgreen;
-webkit-animation: changeBgColor 1.04s ease-in infinite alternate;
}
.loading span{
display: inline-block;
width: 16px;
height: 16px;
border-radius: 50%;
background: lightgreen;
position: absolute;
margin-top: -7px;
margin-left:-8px;
-webkit-animation: changePosition 1.04s ease-in infinite alternate;
}
@-webkit-keyframes changeBgColor{
0%{
background: lightgreen;
}
100%{
background: lightblue;
}
}
@-webkit-keyframes changePosition{
0%{
background: lightgreen;
}
100%{
margin-left: 142px;
background: lightblue;
}
