box-sizing可以分為三個值:
center-box,border和padding不計算入width之內
padding-box,padding計算入width之內
boder-box,border和padding計算入width之內，其實就是怪異模式了
使用時
-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>
