Need help locating the subheadings in css to effect a change of background color

Usually, h1 is main heading while h2, h3, h4 and so on are subheadings. It is like a document where h1 is the biggest heading and therefore main while the smaller headings are for subheadings. In this case, you only have h1 and h2.
