# @colineapp/liquid-glass > Liquid Glass for the web: the rim refraction, light and motion of iOS 27's glass on any rounded element, with React bindings, menus that pour out of their button, and segmented tabs whose thumb clears into a lens. MIT. Version 0.2.0. Install: `npm install @colineapp/liquid-glass`. npm: https://www.npmjs.com/package/@colineapp/liquid-glass. Source: https://upstream.codes/coline/liquid-glass. Playground: https://liquid-glass.coline.space. ### prewarmLiquidGlass(radii?, geometry?) - Type: `(radii?: number[], geometry?: Partial) => void` - Group: More exports Builds the rim for these corner radii while the page is idle, so glass whose corners animate through them is sharp on every frame. By default, every radius a pouring menu passes through (4 to 48px). Floating glass does this when it first appears; call it at startup if your menus mount only as they open. ```ts prewarmLiquidGlass(); ```
