# CSS Clamp Generator

> Generate fluid clamp() values that scale smoothly between two viewport widths.

To create fluid typography, set the size you want at your smallest viewport and at your largest. The generator solves for the slope and intercept and produces a clamp() value that scales linearly between them, then locks at each end.

## FAQ

### What does clamp() actually do?

It takes a minimum, a preferred value and a maximum, and picks whichever is in range. For typography that means text scales with the viewport but never falls below readable or grows absurdly large — replacing a stack of media queries with one declaration.
