html中元素动态生成导致重叠引起布局错乱_html/css_WEB-ITnose
写了一个页面如图 左上角的“运送至：”后面是个ul，其中的li时通过js触法onmouseover动态生成的，ul下面的那个多快好省是个，全局padding：0 ；margin：0；出现问题是当动态生成ul时布局错乱如图 怎么解决？难道把布局改为position：absolute 设置z-index？这样不好吧

没有什么好不好的。只要能实现就可以。一般都是菜单hidden在一个元素中.用js控制display.这样可以不用position:absolute,
你自己分析说下
ul 和后面img的关系
<!DOCTYPE html><html lang="en"><head><meta charset="utf-8" /><title>open source</title><style type="text/css">body{margin:0;padding:0}#nav{ display:inline-block; width:200px; height:50px;line-height:50px; background-color:#ddd;} #nav_menu{background-color:#f1f1f1;margin:0;padding:0}</style></head><body><span id="nav"> shanghai <ul id="nav_menu"> <li>Address</li> <li>Email</li> <li>Map</li> </ul></span></body></html>

用display可以控制列表是否显示，但是显示列表之后还是会影响下面的布局呀。这个是要设置 z 值么？

我把上面列表设置position：absolute布局解决了这个问题。
