placing text on top of an image with CSS

[caesarkim]

I have code like this. I want "Hello World" to be placed on top of 'big_icon.gif' image which is width: 179 height: 35px. The following code doesn't work with firefox and IE. The image appears, but the image is located below the text.

Does anybody know what is wrong with this code?

<style>
.header1 {
  background-image:url("images/big_icon.gif");
  background-attachment: fixed;
  background-repeat: no-repeat;
  background-color: #CCCCCC;
  height: 35px;
  margin-top: 0;
  text-align:
}
</style>
 
<div class="header1">Hello World</div>

Are you attempting to do somethig like this?
hello world!
CSS embedded in head of document (the image is 179 by 35px).
Cursory checked in IE/6, IE/7, and compliant browsers.
