There are a number of selectors that can help you here, but for now we will look at just a couple. In our document, there are two elements — one inside a paragraph and the other inside a list item. To select only an that is nested inside an element, you can use a selector called the descendant combinator, which takes the form of a space between two other selectors.

This also means that if you need to change the look and feel of all paragraphs, you can do it in one location. However, this is still limited to one document — what if you want to define the look of paragraphs for a whole site in one place?
