如何在div中修复背景？

I have a site, and in one of my pages I use a div which looks like an editor. I can have a background in this div and the content above it. I want this background to stay in a fixed position while I am scrolling in the div.

我有一个网站，在我的一个页面中，我使用了一个看起来像编辑器的div。我可以在这个div和它上面的内容中有一个背景。当我在div中滚动时，我希望此背景保持在固定位置。

My code is similar to this:

我的代码与此类似：

 <div id="myEditorArea"  style="vertical-align: top; width: 240px; height: 320px;      background-image: url('image.png'); background-repeat: no-repeat; background-position: center center; background-attachment:fixed; overflow:scroll; text-align: left;">

 bla bla bla

 </div>

The background stays fixed and works ok when I scroll inside the div. The problem is that it is moving when I scroll in the whole page.

背景保持固定，当我在div内滚动时工作正常。问题是当我滚动整个页面时它正在移动。

Does anyone know what could be the problem?

有谁知道可能是什么问题？

Thanks in advance

Here is an example of background-attachment: fixed; http://www.w3schools.com/css/tryit.asp?filename=trycss_background-attachment. That should be what you need.

这是一个背景附件的例子：fixed; http://www.w3schools.com/css/tryit.asp?filename=trycss_background-attachment。那应该是你需要的。
