CSS Modern Features

Category: Product · Sub-category: product-misc

fw:sveltetype:review

Use this skill whenever writing, reviewing, or refactoring any CSS, whether in plain .css files, styled-components, CSS Modules, Tailwind arbitrary values, inline styles in React/Vue/Svelte, or any other frontend context. This skill ensures modern CSS features are used wherever browser support allows — things like clamp(), :has(), container queries, OKLCH colors, scroll-driven animations, anchor positioning, @starting-style, light-dark(), text-wrap: balance, and more. Trigger this skill any time CSS is being written or touched, even indirectly (e.g. a component that needs responsive sizing, a theme system, an animation, a layout). Do NOT default to legacy patterns like px-based media queries, JS-driven animations, or CSS-in-JS workarounds when a native modern CSS feature exists and is supported by the project's browser targets.
