Flexbox Math
SkillDev toolsCalculate and debug Flexbox layout math for flex base size, flex-basis, flex-grow, flex-shrink, the flex shorthand, fractional grow values, and min/max constraints. Use when flex items resize unexpectedly, when distributing free space along one axis, when comparing flexbox with grid, or when deriving predictable card, nav, toolbar, and row layouts.

What this skill tells your AI
The instructions your AI receives, as published by hashgraph-online/awesome-codex-plugins in plugins/LVTD-LLC/skills/skills/flexbox-math/SKILL.md and read by Ahel’s review.
Use this skill for one-dimensional layout distribution. It focuses on the arithmetic that determines base sizes, free space, grow allocation, shrink allocation, and constraint clamping.
Quick Start
- Read
guidelines.mdto select the smallest relevant file set. - Load
references/flex-distribution/rules.mdfor implementation decisions. - Load
references/flex-distribution/examples.mdwhen editing code. - Use
workflows/debug-flex-distribution.mdfor multi-step derivation or debugging.
