The url inside a CSS file is relative to the location of the CSS file.
So if we suppose that you have ~/content/foo.css
and you want to include ~/images/foo.png
here’s how to reference it inside foo.css
:
background-image: url(../images/foo.png);
Don’t use any ~
inside a CSS file. It has no meaning.
So in your case if the CSS file is ~/Content/Site.css
and you want to reference ~/Content/Images/Designs.png
the correct syntax is:
background-image: url(images/designs.png);
If this doesn’t work for you there might be different causes:
- The image doesn’t exist at that location
- You didn’t specify width and height to the containing element so you don’t see the image
What I would recommend you is to use FireBug and inspect the corresopnding DOM element to see exactly what styles and images are applied to it.
