:before and :after are used to insert an inline element containing the content specified by the content attribute before or after the specified element content (rather than the element itself). The most basic usage is as follows :
#example:before { content: "#"; color: red;} #example:after { content: "$"; color: red;}这段代码会在#example元素内容之前插入一个'#'，以及在内容之后添加一个'$'，插入的行内元素是作为#example的子元素.效果为 #Here is the example content$ It should be noted that without the content attribute, the pseudo-class element will have no effect. However, you can specify that the content is empty. As mentioned earlier, the inserted content is an inline element by default and cannot be seen in the HTML source code. This is why it is called a pseudo-class element, so it cannot pass through the DOM. Operate on it.
#example:before { content: ""; display: block; width: 100px; height: 100px;}最后附上2个:befroe 和：after的 例子①八卦图
