.site-nav:after {
    content: "";
    display: table;
    clear: both;
}请问大家这个伪元素什么意思


回复讨论(解决方案)

.site-nav 后面那个元素。

.site-nav 后面那个元素。





是指two这个元素吗

不好意思，这段时间，老是回答错问题的。

anavvvb



a
navvv
b
''after是这里    content: ""; 

.site-nav:before {    content: "";    display: table;    clear: both;}
Copy after login




''  这是before 因为style里设了content='' 也就是说是个空的node(节点)
a
navvv
b

.site-nav:after是.site-nav里内容的后面追加内容
