font-size: clamp(16px, 2vw, 20px);What CSS clamp is
The `clamp()` function lets you define a minimum, flexible preferred value, and maximum in a single expression.
It is one of the simplest ways to create fluid values for typography and spacing without writing several breakpoint-specific rules.
Why clamp is useful for fluid design
Clamp keeps values responsive while still protecting the extremes.
- Text can scale smoothly between small and large screens.
- Spacing can grow without exploding on ultra-wide layouts.
- The minimum and maximum remain explicit and easy to reason about.
Clamp vs media queries
Clamp does not replace every media query, but it reduces the need for many of them.
Media queries are still useful when layout structure needs to change. Clamp is best when a single value just needs to scale smoothly across viewports.
