Frequently Asked Questions
Why use clamp() over media queries?
clamp() scales smoothly on every screen pixel between min and max viewports, eliminating abrupt font-size jumps.
How does the linear slope formula work?
It computes slope = (maxFont - minFont) / (maxViewport - minViewport) to derive dynamic vw and base rem offsets.
