Derive and debug CSS Grid layout math for grid coordinates, line placement, spans, negative indexes, fr units, minmax(), fit-content(), repeat(), auto-fill, and auto-fit. Use when building grid systems, explaining track sizing, troubleshooting fr distribution, placing items by line numbers, or converting a layout sketch into CSS Grid formulas.

# CSS Grid Math
Use this skill when a grid needs to be reasoned about as a coordinate and sizing system. It helps calculate where items land, how tracks divide space, and why flexible tracks do not always produce expected widths.
## Quick Start
1. Read `guidelines.md` to select the smallest relevant file set.
2. Load `references/grid-layout/rules.md` for implementation decisions.
3. Load `references/grid-layout/examples.md` when editing code.
4. Use `workflows/debug-grid-layout.md` for multi-step derivation or debugging.
