Line-height vs letter-spacing: impact on readability and values for body vs headings
This tests whether you distinguish vertical rhythm from horizontal glyph spacing. A strong answer sets body line-height to at least 1.5x per WCAG with minimal tracking, while headings use tighter line-height and tighter tracking. Red flag: identical values.
This tests whether you understand that line-height governs vertical rhythm between baselines while letter-spacing controls horizontal gaps between glyphs, and that each requires context-specific tuning. A strong answer cites WCAG 1.4.12, recommending body text line-height of at least 1.5 times font size with minimal tracking for extended reading, while headings tolerate tighter line-height and may use slightly negative letter-spacing to preserve density and visual weight.
