Design explicit and implicit grids with repeat(), minmax(), and auto-fit/auto-fill.
Learning checklist
- Grid tracks & gaps
- auto-fit vs auto-fill
- Named areas and responsive tracks

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.
Grid Visualizer
Tune templates with repeat(), minmax(), and implicit sizing. Auto-fit fills available space while respecting minimum tracks.
Auto-fit compresses or expands tracks to fill the row; toggle it off to compare with fixed repeat() counts.
