html – Chrome中的SELECT边框呈现3D

这看起来很简单,但我无法解决.

我有一个像这样的简单下拉菜单……

…而且我想应用一个平面边框(没有3D效果),所以我正在使用:

select {
    border:1px solid #CCC;                
}

在这里查看实时样本:http://jsfiddle.net/GqGr3/

它在Firefox和IE中运行良好:

Firefox http://www.re-moto.com/usuario/select-1.png

但它在Chrome中呈现3D:

Chrome http://www.re-moto.com/usuario/select-2.png

这就是它在我的电脑中的工作方式.我在另一台计算机上测试了它,它呈现好.如果发生这种情况,我也会遇到其他用户.

我在Chrome中没有安装任何扩展程序,而且在Windows 7上浏览器是最新的(18.0.1025.151米).

这些是样本的计算样式(包括继承),我没有看到任何奇怪的东西:

任何线索?

最佳答案
有趣……我也在Windows 7 / Chrome 18上,边框的CSS样式正在按预期工作,直到我从Aero切换到’Windows Classic’主题,此时你所描述的行为发生了.上面已经说过,这是一个Windows操作系统问题,但我只是认为这可能会提供一些额外的清晰度.

更新:使用-webkit-appearance:none; CSS规则,似乎可以避免select元素的认操作系统样式.但是,它需要一些额外的CSS来维护元素的主要UI功能(即右侧的箭头按钮).这里有一个工作示例:http://jsfiddle.net/qZF4B/.
