Identify which is an example of a CSS pseudo-element.

• A. ::first-line
• B. :hover
• C. :focus
• D. :nth-child

Answer: (A)

Pseudoelements target a portion of an element’s content rather than the element itself. ::first-line specifically targets the first line of text inside a block, allowing you to style just that portion (like making the first line bolder or a different color) while the rest of the content remains unchanged. The other options are pseudoclasses, which describe a state or condition of an element rather than a portion of its content: :hover applies when the mouse is over the element, :focus when it has keyboard focus, and :nth-child selects elements based on their position among siblings. So the example that fits as a pseudoelement is the one using the double-colon syntax to address a specific part of the content.
