问题描述
我正在使用HTML / CSS创建一个特殊的UI控件来模仿Windows 7控制面板按钮。到目前为止，我的布局正确，现在我想添加一些化妆品。
如此处所示，当您出现渐变时
，其他浏览器不喜欢它。我不知道为什么它不能与其他浏览器一起工作的确切原因 - 我想其原因是要么是实现细节，要么埋在W3规范中。
这适用于所有浏览器：
（我正在使用< base> 标记。 W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
< html xmlns =http://www.w3.org/1999/xhtml>

I'm creating a special UI control using HTML/CSS to mimic the Windows 7 Control Panel buttons. So far, I've got the layout right and now I'd like to add some cosmetics to it.
As seen here, there is a gradient that appears when you hover over the button with your mouse.

Now, you can see here that I've got the layout done. I'd like to add a :hover effect to the whole div item with a background image.
Currently, here is what I have for the CSS- yet it doesn't work. No image shows up in IE8, or FireFox
EDIT: It works in Chrome, but not in FireFox or IE.
#cp .cp-item:hover
{
background:url(images/hoverbg.png) repeat-x;
}
It does however work with a background-color rather than an image.
- There's nothing (relevant) wrong with your CSS.
- The path to your image is correct.
It already works in Chrome.
Chrome seems to be more intelligent (or lenient) than other browsers. If I inspect the page, it's inserting stuff:
It doesn't work in other browsers because you don't have a proper page structure (no doctype, no <html> tag, no <body> tag, etc) - your page doesn't validate, and the other browsers do not "like it". I don't know the exact reason why it doesn't work with the other browsers - I imagine the reason is either an implementation detail, or buried within the W3 spec.
This works in "all browsers":

(I'm using the <base> tag to make the paths work)
It's your exact code, wrapped in typical boilerplate, with the addition of the <base> tag.
