css3实现画对号动画
目标:实现对号动画,慢慢画出来的感觉;
原理:外层div的背景是一个对号图片,用一个div做遮罩,让遮罩div层从左到右做运动一次即可实现动画,需要注意的是遮罩div的初始位置应该在外层div的外面;
代码如下:
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>css对号动画</title> <style type="text/css"> .td { position: relative; background: #5bd8ca url(d.png) no-repeat; width: 24px; height: 35px; overflow: hidden; } .td img { width: 24px; height: 35px; } .mask { position: absolute; width: 24px; height: 35px; animation: myfirst 2s; -moz-animation: myfirst 2s; -webkit-animation: myfirst 2s; -o-animation: myfirst 2s; top: 0; background: #5bd8ca; left: 24px; } @keyframes myfirst { 0% { left: 0; } 100% { left:24px; } } @-moz-keyframes myfirst { 0% { left: 0; } 100% { left:24px; } } @-webkit-keyframes myfirst { 0% { left: 0; } 100% { left:24px; } } @-o-keyframes myfirst { 0% { left: 0; } 100% { left:24px; } } </style> </head> <body> <div class="td"> <div class="mask"></div> </div> </body> </html>
