How to Use Variable Fonts in HTML
01. The Concept
Variable fonts contain multiple variations (weight, width, slant) in a single file, drastically reducing HTTP requests and page weight.
02. Production-Ready Code
font-family: 'Inter Variable';
font-variation-settings: 'wght' 650, 'slnt' -5;
💡 Pro Typography Tip
Check browser support before relying entirely on custom font-variation axes.
