Semantics drive accessibility and SEO. Native elements reduce dependency on heavy scripts. Standards mean your content holds up across browsers and devices.

How to Improve HTML5 Skills

Build for people, search engines, and screens of all sizes:

1. Semantic structure: use <header>, <main>, <article>, <section>, <nav>, <footer> thoughtfully.

2. Accessibility first: meaningful headings, labels, alt text, ARIA only when needed, strong keyboard support, focus management.

3. Responsive images: <picture>, srcset, and correct sizes; don’t overserve pixels.

4. Media done right: <video> and <audio> with captions, transcripts, and accessible controls.

5. Meta and SEO: tidy titles, meta descriptions, canonical tags, and structured data where it helps.

6. Performance: lazy-load media, preload critical assets, defer non-critical scripts, minimize DOM bloat.

7. Validation and testing: validate markup and test across devices, viewports, and assistive tech.

8. Keep learning: track evolving specs and browser support to drop shims as the platform grows.

Clean markup ages well and boosts everything layered on top.
