CSS Validation Warning: Same colors for color and background-color in two contexts

I am getting a ton of warnings like the ones listed below when I do a CSS validation check via http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fwww.gamefriction.com%2FCoded&profile=css21&usermedium=all&warning=1&a开发者_Go百科mp;lang=en

Any ideas how to fix this?

CSS file: gamefriction.com/Coded/css/style.css

What it's saying is that you have the same background color and foreground color in some of your contexts. Example from your CSS (some declarations omitted for clarity):

#red_module_top {
  background: url(http://www.gamefriction.com/Coded/images/red_content_top.jpg) no-repeat;
  color: #fff;
}

Notice how you set the color: #fff. This means your foreground color is white. But your background color is not set. You do set a background image but if for some reason the image is not available, then the background will also be white (because your body tag doesn't define a background color and the validator assumes that it's white), making the text invisible.

You can just add a color to the background line to fix this. For example:

background: #ff0000 url(http://www.gamefriction.com/Coded/images/red_content_top.jpg) no-repeat;

Now what happens is the validator will see that the background is different than the foreground and not complain.

It's complaining for accessibility reasons, that the colors would make it difficult to read the text. If the text color and background color are the same, you couldn't read it at all.
