CSS Clamp Generator
Map a fluid size between two viewport bounds with readable CSS.
A FEW SIMPLE STEPS
How to use it
- Choose minimum and maximum sizes.
- Set the viewport widths for those endpoint sizes.
- Inspect the live preview and copy the CSS expression.
A CONCRETE EXAMPLE
A fluid font size can move from 16 px at a 320 px viewport to 24 px at a 1,280 px viewport.
Know the limits
Viewport bounds must be ordered and units must be explicit. Test text resizing and accessibility in the final layout.
A good question
Does clamp() replace responsive layout testing?
No. It constrains a value; text wrapping, zoom, and the surrounding layout still need testing.
