核心是：找到并且匹配然后显示效果 怎么找？ 通过id 这样说好像太裸铜了把。

代码语言：javascript复制
<li><a href="#p1">李文1</a></li>

记住：#代表要找的为id，p1代表要找到是什么，知道把，记住。是往下找的哈，记住#代表id哈 找到了之后怎么匹配？ 找到了id为p1的之后，就要看看有没有.chapter的了，有就能显现效果了 为什么就能直接显现效果了呢？ 因为:target代表动的时候就触发了哈

代码语言：javascript复制
.chapter:target

怎么显示效果？

代码语言：javascript复制
  border: 1px solid red;
   color: blue;
代码语言：javascript复制
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style type="text/css">
        .chapter:target/*意思是可用于点击的当前的目标元素*/
        {/*再有所有.chapter的class中找出点击的目标元素*/
            border: 1px solid red;
            color: blue;
        }
    </style>
</head>
