Final Answer:
The CSS 2 rule font-face enabled browsers to download font information and thus permitted, in principle, virtually any font to be used on any site. Therefore, the correct answer is A) font-face.
Explanation:
The CSS 2 rule font-face revolutionized web typography by allowing developers to use custom fonts on websites. Before this, web designers were limited to a few "web-safe" fonts that were universally available. With font-face, developers could specify a font file to be downloaded if the user's system didn't have the specified font installed.
This opened up a world of possibilities for typography, enabling more creative and unique designs on the web. Therefore, the correct answer is A) font-face.
