Who this course is for

For graduates of Web Development Intermediate (required prerequisite): you build typed, tested, full-stack applications. This course teaches the platform layer beneath them — the HTML, CSS, and browser engineering that separates an app that works from one that is accessible, fast, secure, and maintainable.

What you will be able to do

  • Architect complex documents: heading order, landmarks, and machine-readable structure
  • Compute and assign accessible names and choose native semantics over ARIA
  • Build native disclosure, dialog, and popover patterns — with invoker commands
  • Deliver responsive media: srcset, sizes, picture, priority hints, and captions
  • Embed third-party content safely with sandbox, permissions, and titles
  • Write machine-readable metadata: viewport, canonical, robots, Open Graph, hreflang
  • Apply progressive enhancement so pages work before JavaScript arrives
