Mostly you’ll read and hear about “webfonts”, but sometimes you’ll also read “@font-face” (-display). In case you wonder what the difference is: basically nothing. They are the same thing. “@font-face” is just the technical correct term for webfonts, so in license agreements this term is likely mentioned. This term is the name of the declaration used in the CSS (Cascading Style Sheets), which defines how to display HTML elements. But when humans talk, they usually don't talk about “@font-face”, but mostly just name it “webfonts”.
