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;} -

这行代码是不是写错了 -

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
