我想从IE下更改蓝色背景颜色，但是我似乎找不到任何CSS这样做。

 < select id = focusSelect>< option>选项< / option>< / select&

JS：

  document.getElementById（focusSelect）。focus（）;

CSS：

 code> select：focus {
 background-color：red; 
}

解决方案

在Internet Exploder 11（不确定以前的版本），你可以这样做

  select：focus ::  -  ms-value {background ：red;}

I'd like to change the blue background color from IE when a drop down is focused, but I can't seem to find any CSS to do this.

<select id=focusSelect><option>Option</option></select>

JS:

document.getElementById("focusSelect").focus();

CSS:

select:focus{
    background-color: red;
}

Specifically this is for when the drop down is not open. Styling the options is not a problem.

I also can't find any definitive answer on whether this is possible to do at all.

Setting the option background color also does not clear the blue color.

option {
    background-color: green;
}

解决方案

In Internet Exploder 11 (not sure about previous versions) you can do this

select:focus::-ms-value {background: red;}
