我正在尝试按照此链接制作下拉列表:http://k-prim.biz/ttpm/workspace-04d.png 这里的诀窍是背景是半透明的,我在名称和下拉菜单上有一个灰色边框。有没有想过用css做这个的想法?
更清楚 - 我想避开这部分边界 - 用户名:k-prim.biz/ttpm/screen.png
提前谢谢!

有可能,但您需要稍微更改HTML
HTML

<div id="username">
ljubo_v
</div>
<div id="userarrow"></div>
<div id="userdrop">
<div id="myhomecork">
myhomecork
</div>
</div>
</div>
css
#user{
position:absolute;

透明背景(CSS3):background: rgba(0,0,0,0.6);
,参数为(red, green, blue, opacity)
(0.00为0%至1.00为100%)。
要重叠项目,请设置主菜单项position: relative;
(以下内容正常工作所需):制作子导航position: absolute;
。它将是绝对的,但相对于顶部菜单项。您可以使用负位置值来重叠元素。
