css3 box-sizing属性和JS 网页等比例缩放

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

例：

<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>
