HTML elements can be CSS selectors, but as we saw with the universal selector
*, they're not the only selectors available.
There are two important selectors you can use in addition to the universal selector and HTML elements: classes and IDs.
You'll see a class and an ID declared in the HTML tab. We'll get to the syntax for these in the next exercise—in the meantime, remove the comment (the leading
/* and trailing
*/) from the CSS tab to see how they work!
