Answer: Use the CSS ":nth-child" selector

    This shows how to focus on the background of alternate table row using the CSS3 :nth-child selector. The :nth-child(N) pseudo-class accepts an argument N, which can be a keyword, a number, or a number expression of the shapxn+y wherex and y are integers (e.g. 1n, 2n, 3n, 2n+1, 3n-2, …).
