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。

我用Bootstrap找到了你的案子。这是最简单的解决方案：

博客文章HowtoCSS表单下拉样式没有JavaScript适合我，但在Opera中失败了：

＜select＞标签可以通过CSS进行样式设置，就像在浏览器中呈现的HTML页面上的任何其他HTML元素一样。下面是一个（过于简单）的示例，它将在页面上放置一个select元素，并将选项的文本呈现为蓝色。
示例HTML文件（选择Example.HTML）：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Select Styling</title>
<link href="selectExample.css" rel="stylesheet">
</head>
<body>
<select id="styledSelect" class="blueText">
<option value="apple">Apple</option>
<option value="orange">Orange</option>
<option value="cherry">Cherry</option>
</select>
</body>
</html>
示例CSS文件（selectExample.CSS）：
/* All select elements on page */
select {
position: relative;
}
/* Style by class. Effects the text of the contained options. */
.blueText {
color: #0000FF;
}
/* Style by id. Effects position of the select drop down. */
#styledSelect {
left: 100px;
}

注意：base64在SVG中是一个V字形。
在设置选择下拉列表样式时，我注意到的最大的不一致是Safari和Google Chrome渲染（Firefox可以通过CSS完全自定义）。在互联网的黑暗深处进行了一些搜索后，我发现了以下内容，这几乎完全解决了我对WebKit的疑虑：
Safari和Google Chrome修复程序：
select {
-webkit-appearance: none;
}
但是，这会删除下拉箭头。您可以使用带有背景、负边距或绝对位于select下拉列表上方的附近div添加下拉箭头。
*CSS属性：-webkit外观中提供了更多信息和其他变量。
