Frequently Asked Questions
How does CSS clamp() fluid typography work?
The formula calculates a mathematical slope between viewport widths, scaling the font size linearly with viewport width (vw) between the defined minimum and maximum boundaries.
Why use rem with clamp() instead of raw pixels?
Using rem units preserves user accessibility preferences when browser default font size settings are modified.
