How to remove background color from list items on a twitter bootstrap button dropdown menu?
提问by nabucosound
I am struggling with the button dropdowns, I cannot remove the blue background color that appears when hovering through the menu list items. I tried changing the a:hover CSS but with no success. Maybe this background color is dinamically added with javascript?
我在按钮下拉菜单中苦苦挣扎，无法删除悬停在菜单列表项中时出现的蓝色背景色。我尝试更改 a:hover CSS，但没有成功。也许这个背景颜色是用javascript动态添加的？
Thanks!

Action
<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li><a href="#">link me</a></li>
<li><a href="#">link me too</a></li>
</ul>
</div>

It looks like the CSS background color is not applied to the element. Why?
看起来 CSS 背景颜色没有应用于元素。为什么？

This should work
这应该工作
.dropdown-menu li a:hover :focus {
color:black;/*color turns white if not changed*/
background: none;
}
