You use relative paths in a .css file, they are relative to the location of the stylesheet, not the location of the current page:-

a.external
{
  background-image:url('external-link.gif');
  background-repeat:no-repeat;
}

will look for an image called 'external-link.gif' in the same directory as the .css file.

So if your directory structure looks like:-

• {Domain Root}
• Content
• Content\Style.css
• Images
• Images\MyImage.png

you could reference MyImage.png from Style.css with:-

url('../Images/MyImage.png')

Then if you moved your application into a subdirectory:-

• {Domain Root}
• Site
• Site\Content
• Site\Content\Style.css
• Site\Images
• Site\Images\MyImage.png

The same url ('../Images/MyImage.png') still finds the image because the relative path between the two resources has not changed.
