是否有CSS唯一的方式来设置＜select＞下拉列表的样式？
我需要尽可能人性化地设置＜select＞表单的样式，而不需要任何JavaScript。在CSS中，我可以使用哪些财产来执行此操作？
此代码需要与所有主要浏览器兼容：
Internet Explorer 6、7和8Firefox浏览器游猎
我知道我可以用JavaScript实现：示例。
我说的不是简单的造型。我想知道，我们只能用CSS做什么。
我在Stack Overflow上发现了类似的问题。
还有Doctype.com上的这个。
当前回答
label {
position: relative;
display: inline-block;
}
select {
display: inline-block;
padding: 4px 3px 5px 5px;
width: 150px;
outline: none;
color: black;
border: 1px solid #C8BFC4;
border-radius: 4px;
box-shadow: inset 1px 1px 2px #ddd8dc;
background-color: lightblue;
}
这对选定的元素使用了背景色，我删除了图像。。

一个使用：after和：before来完成这个技巧的非常好的例子是在使用CSS3 | CSSDeck设置选择框的样式中
对您可以通过标记名来设置任何HTML元素的样式，如下所示：
select {
font-weight: bold;
}
当然，您也可以像其他任何元素一样使用CSS类来设置其样式：
<select class="important">
<option>Important Option</option>
<option>Another Important Option</option>
</select>
<style type="text/css">
.important {
font-weight: bold;
}
</style>
从InternetExplorer10开始，您可以使用：：-ms-expand伪元素选择器来样式和隐藏下拉箭头元素。
select::-ms-expand {
display:none;
/* or visibility: hidden; to keep it's space/hitbox */
}
其余的样式应该与其他浏览器类似。
下面是Danield的jsfiddle的一个基本分支，它应用了对IE10的支持
我用Bootstrap找到了你的案子。这是最简单的解决方案：

注意：base64在SVG中是一个V字形。
