box-sizing属性可以为三个值之一:content-box(default),border-box,padding-box。
content-box,border和padding不计算入width之内
padding-box,padding计算入width内
border-box,border和padding计算入width之内,其实就是怪异模式了~
ie8+浏览器支持content-box和border-box;
ff则支持全部三个值。
使用时:
-webkit-box-sizing: 100px; // for ios-safari, android
-moz-box-sizing:100px; //for ff
box-sizing:100px; //for other
栗子:
<style type="text/css"> .content-box{ box-sizing:content-box; -moz-box-sizing:content-box; width: 100px; height: 100px; padding: 20px; border: 5px solid #E6A43F; background: blue; } .padding-box{ box-sizing:padding-box; -moz-box-sizing:padding-box; width: 100px; height: 100px; padding: 20px; border: 5px solid #186645; background: red; } .border-box{ box-sizing:border-box; -moz-box-sizing:border-box; width: 100px; height: 100px; padding: 20px; border: 5px solid #3DA3EF; background: yellow; } </style>
