How to Change Font Size in HTML

01. The Concept

In modern web design, hard-coding pixel sizes creates accessibility issues. You should use relative units like REM or fluid functions like clamp() to dynamically scale your text.

02. Production-Ready Code

font-size: clamp(1rem, 2vw + 0.5rem, 1.5rem);

💡 Pro Typography Tip

Always set your root html font-size to 100% and use REMs for paragraphs.
