Understand Responsive Font Scaling

Responsive typography helps keep your text readable on any device without media queries. The clamp() CSS function ensures your font size adapts fluidly within a specified range.

What Is CSS Clamp?

clamp() accepts three values: a minimum font size, a preferred scaling value, and a maximum size. It ensures the font never goes below or above the set boundaries while scaling fluidly within.
