Chrome中的SELECT边框呈现3D [英] SELECT border in Chrome renders 3D

问题描述

我有一个简单的下拉菜单，就像这个...

 < select> 
< option value =1>选项1< / option> 
< / select> 
  

...并且我想应用平坦边框（无3D效果），所以我使用：

  select {
 border：1px solid #CCC; 
} 
  

请参阅实时示例： http://jsfiddle.net/GqGr3/

它工作正常在Firefox和IE：

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原理。我在第二台计算机上测试了它，并呈现OK。如果发生这种情况，我也会遇到其他用户。

我没有在Chrome中安装任何扩展程序，并且浏览器是最新的（18.0.1025.151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？

解决方案有趣的...我也在Windows 7 / Chrome 18上，边框的CSS样式按预期工作，直到我从Aero切换到Windows Classic主题， / strong>此时您描述的行为发生。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，可以避免元素的默认操作系统样式选择元素。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）。这里有一个可用的示例： http://jsfiddle.net/qZF4B/ 。

This looks very simple but I can't solve it.

I have a simple drop down menu like this one...

<select>
    <option value="1">Option 1</option>
</select>

...and I want to apply a flat border (no 3D effect), so I'm using:

select {
    border:1px solid #CCC;                
}

See live sample here: http://jsfiddle.net/GqGr3/

It works fine in Firefox and IE:

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

but it renders 3D in Chrome:

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

That's how it works in my computer. I tested it on a second computer and it renders OK. If this is happening to me it my also happen to other users.

I don't have any extensions installed in Chrome and the browser is up to date (18.0.1025.151 m), on Windows 7.

解决方案

Intriguing... I'm also on Windows 7/Chrome 18 and the CSS styling for the border is working as expected, until I switch from Aero to a 'Windows Classic' theme, at which point the behavior you've described occurs. It's already been stated above that this is an Windows OS issue, but I just thought this might offer some additional clarity.

UPDATE: Using the -webkit-appearance: none; CSS rule, it appears that the default OS styling of the select element can be avoided. However, it requires a bit of extra CSS to maintain the staple UI features of the element (namely the arrow button at the right). A working example is available here: http://jsfiddle.net/qZF4B/.
