伪对象选择器包含三种，分别为：

E::selection

E::after

E::before

其中before和after必须与content结合使用，如果content想用几何图形要加 \ 进行转义，content里面的内容相当于文字，可以通过color改变颜色，font-size改变大小

等等。

其书写方式为：

#E::before{<br>    content:"\25C0";//获取的方法<br>    color: rgba(254, 0, 0, 0.6);//可以改变它的颜色<br>    font-size: 20px;//可以改变它的大小<br>    position: relative;<br>    left: -29px;//改变位置<br>}

Copy after login
