Deep dive

Why this matters

Principles, mental models, and debugging clues tailored to the topic.

Visual intuition

Each property is paired with motion or color feedback so you build muscle memory, not just recall syntax.

Copy-ready CSS

Controls emit exact CSS you can copy. Use it as a starter token or paste into DevTools for instant validation.

Performance notes

Learn where reflow, repaint, or compositing occurs so you avoid jank and choose GPU-friendly paths.

Accessibility first

Focus-visible, reduced-motion, and contrast tips are woven into every lab to keep experiences inclusive.

Practice

Try recreating a UI card using this topic. Toggle between dark and light modes to validate token contrast and responsiveness.

Tip: use DevTools overlays (grid/flex) plus the copy CSS button.
