给li增加样式

怎么增加呢,加在哪里

给li增加样式

  •  具体的你要自己调

    大小改好后,字体不能居中,一直靠近最底端,设置了好几个属性也不行

  •  具体的你要自己调

    大小改好后,字体不能居中,一直靠近最底端,设置了好几个属性也不行


  •  具体的你要自己调
    line-height:15px;

    这样是不可以的

    怎么都 没人那

    line-height: 150%

    修改之前要弄清楚三级菜单之间的关系,原来的是在父级a标签里定义高度、行间距了,下面的二、三级菜单就自动继承了。
    解决办法就是:不要在父级定义,分别在各子级定义。

    .menu ul li a, .menu ul li a:visited {display:block; text-decoration:none; color:#000;width:104px; text-align:center; color:#fff; border:1px solid #fff; background:#710069; font-size:11px; overflow:hidden;} .menu ul li {float:left; margin-right:1px; position:relative; line-height:40px;} /*一级菜单项*/.menu ul li:hover ul li { line-height:30px;}/*二级菜单项*/.menu ul li:hover ul li ul li{ line-height:30px;}/*三级菜单项*/
