Which CSS3 selector can you use to apply a style to the first paragraph of every container in a Web page?

• A. div:first-of-type
• B. p:nth-of-type(1)
• C. p:first-of-type
• D. p:first-child

Answer: (C)

Targeting the first paragraph inside each container uses the :first-of-type pseudo-class. It selects a paragraph only if it is the first p among its siblings, so every container that directly holds a paragraph will have its first paragraph styled, regardless of what other elements appear before it. This is why it’s the best fit for “the first paragraph of every container”—it’s clear and robust for that intent. The alternative that would pick the first div targets a different element altogether, and requiring the paragraph to be the very first child would fail whenever another element comes before the first paragraph. While p:nth-of-type(1) can work similarly in many cases, first-of-type expresses the idea much more directly and is the standard way to select the first occurrence of a given element type.
