Web Foundations
How the web works, how to use the browser as a studio, and the HTML, CSS, and JavaScript for your first real page.
Explore path01 / THE METHOD
A better way to become excellent
Every lesson is built around a decision, a small artifact, and a clear definition of done. Read less. Make more. Explain what changed. Ship something another person can use.
02 / CURRICULUM
Six paths. Thirty-six studio lessons.
New here? and we’ll point you somewhere useful.
How the web works, how to use the browser as a studio, and the HTML, CSS, and JavaScript for your first real page.
Explore pathSemantic HTML, expressive CSS, resilient JavaScript, performance, and the browser capabilities that landed in 2026.
Explore pathTurn real needs into clear flows, useful interfaces, honest feedback, and products people can understand.
Explore pathBuild for different bodies, minds, devices, and situations using WCAG 2.2 and human testing.
Explore pathCreate original, evidence-rich information that people, search systems, and generative experiences can trust.
Explore pathDesign useful AI features with good context, streaming UX, evaluations, safety, and human control.
Explore path03 / THE PLATFORM NOW
Verified for August 2026
These capabilities crossed the interoperability line or arrived in current engines. Use the stable core; layer newer ideas as progressive enhancements.
Place a tooltip, menu, or callout relative to its trigger—and let the browser choose a fallback when space runs out.
Baseline 2026Respond to a component’s custom-property state, not only its dimensions. Design systems can become genuinely contextual.
Baseline 2026:open and gap decorationsStyle open controls consistently, and decorate Grid or Flexbox gaps without extra borders or pseudo-elements.
New in 2026Observe and coordinate navigations with a single modern interface while preserving links, history, and progressive enhancement.
Baseline 2026Move DOM XSS protection into enforceable browser policy instead of relying only on team discipline and code review.
Baseline 2026Build spatial continuity and scroll-linked storytelling in CSS, with reduced-motion behavior kept as a first-class requirement.
Progressive04 / LIVE LAB
Read it. Change it. See it.
Edit the specimen and run it. The preview is sandboxed, so experimentation stays in the lab.
05 / WHAT GOOD LOOKS LIKE
The portfolio is the assessment. By the end, you will have made artifacts that prove what you can do.
Works with a keyboard, screen reader, touch, and no JavaScript.
Adapts at the component level and stays stable under real content.
Useful to a person, indexable by search, and easy to cite accurately.
Evaluated, observable, privacy-aware, and clear about uncertainty.
06 / FIELD NOTES
Short, practical, current
Official feature status, without the guesswork.
↗ AccessibilityUse the stable standard; follow WCAG 3 as work in progress.
↗ DiscoveryOriginal value and crawlable fundamentals remain the foundation.
↗ PerformanceDesign for lived experience, not only a lab score.
