Framework example

Choose Astro, React, or Elements to compare native usage against the shared visual output. Each example assumes the framework-level setup is already complete.

Framework usage

Switch targets to compare the adapter code. This live preview runs the Astro example. React and Elements use their own behavior APIs; complete the matching framework setup before copying an example.

Choose your target

Add this component

Choose the package for your runtime. All adapters share the Lumen stylesheet. Use the matching registry command when you want a local wrapper for that framework.

Glass

Add the glass prop to apply the shared blur, saturation, border, and highlight tokens. Glass reads best over vivid content, so place the surface above imagery or color.

API reference

Lumen-specific props and runtime attributes for the Astro primitive. Use the framework differences above and the copyable examples for React composition and Elements attributes; the public adapter types define their supported contracts.

Attribute	Values	Default	Description
glass	boolean \| "subtle" \| "strong"	false	Applies the tokenized liquid-glass surface treatment with backdrop-filter fallbacks; "subtle" and "strong" adjust the fill intensity.
variant	"default" \| "unstyled"	"default"	Keeps aside semantics while removing Lumen layout and presentation.
class, className	string	""	Merges custom classes with the generated ui-* root classes.
...native attributes	HTML attributes	-	Forwards standard attributes to the root element unless the component consumes them.
