设置为 DIV 背景的图像在 IE 中显示，但在 Firefox 中不显示.

An image set as the background of a DIV is displayed in IE, but not in Firefox.

CSS 示例:

div.something {
background:transparent url(../images/table_column.jpg) repeat scroll 0 0;
}

(这个问题在很多地方都有描述，但没有看到任何结论性的解释或修复.)

推荐答案

对不起，这有点大，但它涵盖了我一直发生的两种可能性.

Sorry this got huge, but it covers two possibilities that consistently happen to me.

您可能会发现 CSS 文件的路径不正确.例如:

You may find the path to the CSS file isn't correct. For example:

假设我有以下文件结构:

Say I have the following file structure:

public/
    css/
        global.css
    images/
        background.jpg
    something/
        index.html
    index.html

在 public/index.html 上，以下路径将包含 CSS 文件:

On public/index.html the following paths will include the CSS file:

#1:  <link href="./css/global.css"
#2:  <link href="/css/global.css"
#3:  <link href="css/global.css"

但是在 public/something/index.html 上，数字 1 和 3 会失败.如果您使用这样的目录结构(或 MVC 结构，例如:http://localhost/controller/action/params)，请使用第二种 href 类型.

However on public/something/index.html number 1 and 3 will fail. If you are using a directory structure like this (or an MVC structure e.g.: http://localhost/controller/action/params) use the second href type.

Firebug 的网络监视器选项卡会告诉您是否无法包含 CSS 文件.

Firebug's Net monitor tab will tell you if the CSS file can't be included.

关于路径，请记住图像是相对于 CSS 文件的路径的.所以:

On the subject of paths remember that images are relative to the path of the CSS file. So:

url('./images/background.jpg') /* won't work */
url('../images/background.jpg') /* works: ../ == up one level */

将鼠标悬停在 Firebug 的 CSS 选项卡中背景属性的 url() 部分以检查文件是否正在加载.

Hover over the url() part of the background attribute in Firebug's CSS tab to check if the file's being loaded.

可能是 div 没有内容，因此高度为 0.确保 div 中至少有一行内容(例如:lorem ipsum delors secorum)或:

It could be that the div has no content and thus has a 0 height. Make sure the div has at least a line of something in (e.g.: lorem ipsum delors secorum) or:

div.something {
    display: block; /* for verification */
    min-height: 50px;
    min-width: 50px;
}

检查 Firebug 的布局选项卡(HTML 选项卡)以检查 div 的高度/宽度.

Check Firebug's layout tab (of the HTML tab) to check the div has a height/width.
