About css-grid-math
A skill for reasoning about CSS Grid as a system of coordinates and track sizing. It guides layout calculations, implementation choices, and debugging through focused references and workflows.
Key features
- 01Calculate item placement and track sizes
- 02Explain flexible track sizing
- 03Route tasks to relevant references
- 04Provide debugging workflows and examples
Use cases
- 01Work out where grid items will be placed
- 02Diagnose unexpected flexible track widths
- 03Apply grid rules while editing layouts

From the project READMECSS 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
- Read
guidelines.mdto select the smallest relevant file set. - Load
references/grid-layout/rules.mdfor implementation decisions. - Load
references/grid-layout/examples.mdwhen editing code. - Use
workflows/debug-grid-layout.mdfor multi-step derivation or debugging.
