<!--你写的当hover“ .nav_1” 它的时候下面的所有div显示 所有滑动 “.nav1的时候”三级目录也就跟随二级目录 一起显示出来了 我都给你改正了 你看下 就是hover的时候分隔开来 不让其他的受影响--> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style type="text/css"> .page{ width:100%; height:2000px; } *{ padding: 0; margin: 0; font-family: "microsoft yahei"; } .nav{ width: 160px; height: 40px; background: #666; position: fixed; top: 50%; left:0; color:#fff; line-height: 40px; text-align: center; margin-top: -82px; cursor: pointer; } .nav_1{ border-bottom: 1px solid #fff; } .nav_1_content>div{ height:auto; width: 160px; border-bottom: 1px dashed #fff; background: #666; } .nav_1:hover .nav_1_content{ display: block; } .nav_1_content{ color:red; display: none; position: absolute; left:160px; top:0; } .nav_3title{ width: 160px; height: auto; background: #666; display: none; color:violet; position: absolute; left:160px; top:0; } .nav_3{ border-bottom: 1px solid #fff; } .nav_2:hover .nav_3title{ display:block; } </style> </head> <body> <div class="page"> <div class="nav"> <div class="nav_1"> <div class="nav_1_title">一级目录</div> <div class="nav_1_content"> <div class="nav_2">二级目录 <div class="nav_3title"> <div class="nav_3">三级目录</div> <div class="nav_3">三级目录</div> <div class="nav_3">三级目录</div> </div> </div> <div class="nav_2">二级目录 <div class="nav_3title"> <div class="nav_3">2</div> <div class="nav_3">三级目录</div> <div class="nav_3">三级目录</div> </div> </div> </div> </div> </div> </div> </body> </html>
