Applications

Perfect for responsive typography, fluid spacing, and creating viewport-aware layouts. Works across all modern browsers for fluid design systems.

How It Works

CSS clamp() uses the formula: clamp(min, preferred, max). The preferred value is typically a fluid calculation using viewport units (vw, vh) combined with fixed units (rem, px). The browser interpolates between min and max based on viewport size.

Fun Fact: CSS clamp() is supported in all modern browsers since 2019 and eliminates the need for complex CSS media queries for simple fluid scaling.
