Detailed Topics & Submodules

HTML Semantics & Document Structure

Write SEO-friendly, accessible markup conforming to modern HTML5 standards.

Why It Matters: Search engines and screen readers rely on well-structured layouts to index and explain website content.
Skills:Semantic layout tagsAccessibility treesSEO indexing

CSS Grid, Flexbox & Layout Engines

Deep dive into CSS formatting contexts, flex lines, grid tracks, and modern positioning APIs.

Why It Matters: Creating responsive, stable visual interfaces prevents layout jumping and visual glitches.
Skills:Grid template layoutsFlex alignment contextsPositioning overrides

Critical Rendering Path & Event Loop

Trace DNS resolution, TCP handshake loops, TLS negotiation, and V8 event loop scheduling.

Why It Matters: Understanding the browser's execution thread is vital to optimize Core Web Vitals.
