CSS中的border-box和content-box有什么区别?
我不清楚这两个盒子之间的关系。例如,
box-sizing:border-box;
和box-sizing:content-box;
这两种风格的输出看起来很相似。

大小调整: border-box ;使用人们已经与Internet Explorer关联的盒子模型,其中填充和边框的尺寸包含在元素的尺寸中。 (图片source)

添加了演示。
$("#content").on("click", function() {
$("*").css("box-sizing", $(this).text());
});
$("#border").on("click", function() {
$("*").css("box-sizing", $(this).text());
});

.parent {
width: 50%;
border: 5px solid #E18728;
float: left;
}
.child {
width: 90%;
padding: 20%;
border: 4px solid black;
margin: .5em auto;
}
.twins {
width: 50%;
padding: 1em;
border: 4px solid black;
float: left;
}
