B %

C px

D vh

rem scales relative to the root font size, making it ideal for responsive typography.

What does the CSS function clamp() do for font sizes?

B Chooses the smallest font size

C Sets a fixed font size

D Limits font size between a minimum and maximum

clamp() restricts font size to stay between a minimum and maximum value, adjusting fluidly.

Why avoid using px units alone for responsive typography?

A They are too small

B They cause text to be bold
