Frequently asked questions
What is fluid typography?
Fluid typography uses CSS clamp(), calc(), and viewport units (vw) so font sizes grow and shrink smoothly and continuously between defined minimum and maximum boundaries, rather than abruptly jumping at media query breakpoints.
How does clamp() work for font sizes?
clamp(min, preferred, max) accepts three parameters: an absolute minimum floor, a fluid preferred rate of change (e.g. 0.833rem + 0.833vw), and an absolute maximum ceiling. The browser automatically selects the middle value.
When should I use fluid typography vs breakpoints?
Use fluid sizing for headlines, display titles, and hero text that should feel harmoniously proportioned across all screen widths. Pair it with fixed body text (minimum 16px) for predictable multi-line reading comfort.
