Well, the CSS validator shows you at which line the error/warning is, so that is already a start.

Now to what (example)

Same colors for color and background-color in two contexts .caseStudy-table ul li.boldtext and a:hover

means:

Your background color is the same as the text color. The validator shows a warning because it might not be possible to read the text. (Ever try to read white text on white background?)

.caseStudy-table ul li.boldtext {
    background-color : #29a1d6; /* background-color */
    color : #ffffff;
    font-weight : bold;
}

a:hover {
    color : #29a1d6; /* text color */
}

If you don't have a link in .caseStudy-table ul li.boldtext then it is ok. That is why the message is a warning and not an error.

The nasty thing here is that the mentioned color is used in the hover pseudo class for anchors, globally, so whenever you move your mouse over a link in the caseStudy-list-"context", it hides.
