.nav ul li ul{ displaxy: none; margin-left:10px; padding:0; width: 100px; background-color: rgb(224223228); position: relative;}.nav ul li:hover ul{display:block}.nav ul li ul li { float:none; font-size:12px; width:auto; text-align: center; margin:0; background-color: rgb(224223228);}.nav ul li:hover ul li a:hover{ border-color: rgb(104140140);width:auto;display:block;margin:0px;} <ul> <li><a href="""">我的大学</a> <ul> <li><a href="""">学校概况</a></li> <li><a href="""">校园风光</a></li> <li><a href="""">BT DOWN</a></li> </ul></li> </ul>时间： 2024-09-14 07:45:49
