What problem does it solve? Web interfaces often ship with typography issues that only appear at real content lengths: bad wrapping, orphaned words, synthesized font weights, shifting numbers, and broken heading hierarchy. This Skill provides a systematic review checklist and exact CSS values to make text render, wrap, and behave correctly across a product. ## Core Features & Use Cases - Type system enforcement: Defines semantic type scales, descending heading sizes, role-based line-height and letter-spacing rules, and measure caps of 60-75 characters per line. - Rendering and wrapping fixes: Covers text-wrap balance/pretty, truncation with ellipsis and line-clamp, tabular numbers for changing values, font-metric underlines, and iOS 16px input zoom fixes. - Variable fonts and OpenType guidance: Explains when to use font properties over raw axis/feature tags, how to avoid synthesized faces, and how to enable small caps, superscripts, and stylistic sets. - Use Case: While reviewing a dashboard UI, you notice a price column shifting as values update and a card description clipped awkwardly. This Skill directs you to apply font-variant-numeric: tabular-nums and line-clamp with a tooltip fallback, with Tailwind equivalents from the cheat sheet. ## Quick Start Review the typography in my dashboard page and report any wrapping, hierarchy, or font-loading issues with fixes.
