LVTD-LLC 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
- 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.
