(red serifs)

In typography, a serif is a small line or stroke regularly attached to the end of a larger stroke in a letter or symbol within a particular font or family of fonts. A typeface or "font family" making use of serifs is called a serif typeface (or serifed typeface), and a typeface that does not include them is a sans-serif one. Some typography sources refer to sans-serif typefaces as "grotesque" (in German, "grotesk") or "Gothic", and serif typefaces as "roman".
