1. Serif vs. Sans-serif
Whether designers should use serif or sans-serif fonts for body copy is one
of the most discussed and unresolved questions about typesetting on the
web. Some designers prefer to give their headlines serifs (which are short,
decorative lines at the end of letter strokes) to give them more appeal. The
main reason to choose a serif font for your headlines is that, at a large size,
serif fonts are easy to read and look great. The contrast between a serif font
for headlines and a sans-serif font for body copy can be interesting, too.
Some designers prefer serif fonts for body copy because they believe the
lines at the end of letter strokes help guide readers from one letter to the
next, making scanning and reading more comfortable.
