1-1-3.css易混淆的样式
css3 box-sizing属性
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
<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>
