Responsive Layout Math
SkillDev toolsDerive, review, and debug responsive web layout math for fluid widths, media query ranges, viewport units, percentages, and CSS clamp() formulas. Use when building responsive layouts, converting fixed designs to fluid CSS, calculating breakpoints, choosing vw/svw/lvw/dvw units, or deciding whether CSS math or JavaScript measurement should own a layout behavior.

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/responsive-layout-math/SKILL.md and read by Ahel’s review.
Use this skill to turn fixed layout intentions into proportional, bounded, and testable responsive CSS. It is strongest when the task involves deriving a formula rather than picking arbitrary breakpoint values.
