HTML里select的CSS样式的改变

本以为可以很简单的在CSS里像input那样的给解决，结果没想到试了一下才知道常规的CSS根本没法改变的select样式，CSS里怎么弄，select都仍然是默认的那三维的样式。于是在网上搜索了一下，才知道，原来这个select是不能用常规的方法来定义CSS样式的。要用特殊的方法来处理。相信有很多朋友在处理网页的时候都会遇到这个问题，于是找了一篇不错的文章转过来，希望对大家有帮助――――

首先要告诉大家，如果你是用css的方法，除了箭头部分，其他都可以改变，这是很令人别扭的事，因为其他的样式改了，箭头部分改不了等于无用。
下面举个css改select的例子

如果你想彻底的改变select的样子，有一种方法是用htc，但它有个缺点就是除了ie内核的，其他的他不支持。

第二种方法就是用js，这其实是模拟select的效果，代码如下：
