Mobile-First HTML Structure
Over 60% of web traffic is mobile. Responsive HTML starts with the viewport meta tag and structured content that reflows gracefully before CSS even loads.
Why responsive HTML Matters
Google indexes mobile-first; if your HTML structure breaks on small screens, you lose mobile rankings regardless of CSS quality.
Viewport meta, logical heading order, and responsive images in HTML ensure content is parseable before stylesheets load.
