问题描述

如何更改此下拉菜单中的蓝色突出显示？

How do I change the blue highlight on this dropdown please?

以下是代码： -

<style>
select { border:0; color:#EEE; background:transparent;
font-size:20px; font-weight:bold; padding:2px 10px; width:378px;

#mainselection { overflow:hidden; width:350px;

}
</style>

</head>
<body>

    <div id="mainselection">
    <select>
    <option>Select an Option</option>
    <option>Option 1</option>
    <option>Option 2</option>

如果可能，我想将突出显示颜色更改为灰色。

I'd like to change the highlight color to gray if this is possible.

推荐答案

我相信你正在寻找大纲 CSS属性psuedo属性）：

I believe you are looking for the outline CSS property (in conjunction with active and hover psuedo attributes):

/* turn it off completely */
select:active, select:hover {
  outline: none
}

/* make it red instead (with with same width and style) */
select:active, select:hover {
  outline-color: red
}

style和outline-width
