Frequently asked questions
What does CSS clamp() do?
It sets a value that scales fluidly between a minimum and maximum based on viewport width, avoiding abrupt jumps at media query breakpoints.
Can I use this for spacing, not just font size?
Yes, the generated clamp() value works for any CSS property that accepts a length, such as padding, margin, or width.
How do I preview the effect?
Drag the resize handle on the preview box to simulate different viewport widths and see the font size change smoothly.
