How can you select all p elements within a div element in CSS?

The choice that accurately selects all p elements within a div element is through the selector div p. This selector works by targeting all paragraph (p) elements that are descendants of the div. In CSS, if you want to select an element nested inside another element, you can simply place the parent selector followed by a space and then the child selector.

Thus, the syntax div p indicates that you want to select every p element that resides anywhere within a div, regardless of how deeply nested it might be (as long as it is a descendant).

In contrast, other selections like p div would look for div elements inside a p, which is not the intent here. The div > p selector only targets direct child p elements of a div, thereby not selecting any p that are further down the hierarchy. Lastly, the div+p selector is used to select a p that immediately follows a div, which also differs from selecting all p elements within the div.
