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1种效果:
代码如下:
- <divclass="loading">
- <span></span>
- <span></span>
- <span></span>
- <span></span>
- <span></span>
- </div>
- .loading{
- width:80px;
- height:40px;
- margin:0auto;
- margin-top:100px;
- }
- .loadingspan{
- display:inline-block;
- width:8px;
- height:100%;
- border-radius:4px;
- background:lightgreen;
- -webkit-animation:load1seaseinfinite;
- }
- @-webkit-keyframesload{
- 0%,100%{
- height:40px;
- background:lightgreen;
- }
- 50%{
- height:70px;
- margin:-15px0;
- background:lightblue;
- }
- }
- .loadingspan:nth-child(2){
- -webkit-animation-delay:0.2s;
- }
- .loadingspan:nth-child(3){
- -webkit-animation-delay:0.4s;
- }
