动态加载li下的ul中的li,li之间的间隔怎么消除,在CSS里写的好像没用?

菜单的第一级也是通过ajax获取的,需要样式也发过来吗?

代码发出来,才知道错误在哪里

weibo_哆啦A梦有大口袋_0

你说的清除li之间的间隔是代码之间的间隔还是HTML布局上的间隔<ul>                <li><a href="#">调度基础数据</a><span>></span></li>                <li><a href="#">调度基础数据库</a><span>></span> </li>                <li><a href="#">电网</a><span>></span></li>                <li><a href="#">总调直调电网</a><span>></span></li>                <li><a href="#">变电站</a><span>></span></li>                <li><a href="#">500kV海港变电站</a><span>></span></li>            </ul>

FireBind

ul{padding:0px;margin:0px;}

weibo_哆啦A梦有大口袋_0

这行代码是不是写错了

陌卍言

浏览器自带的默认样式,请百度重置样式

Mine丶Yt

设个全局样式:ul,li{padding:0px;margin:0px;list-style:none;}看看
