Alert
Free · MITHeadless, accessible, and styled entirely through the attribute surface below — bring your own CSS system, or start from the reference theme.
Install
Without a flag you get no styling at all — plain HTML carrying the attribute surface below. --theme copies the same theme in two dialects;--bridge lumos re-points either one onto Lumos for Astro's tokens (it needs a theme to re-point, and Lumos itself, already in your project).
Unstyled — behavior only, you write the CSS

Attribute surface
With no class-merging machinery, these attributes are the whole extension point. State is a data-attribute or a native attribute; visibility is the hiddenattribute. Generated from source by pnpm slots.
| Component | Slots | Variants | Runtime state | Native state |
|---|---|---|---|---|
| `Alert.astro` | `alert` | `data-variant`: `info` · `success` · `warning` · `error` | — | — |
Source
What the command copies — 2 files, alias-free so the copy lands standing alone. This is the whole component; there is nothing else.
---
// src/components/ui/display/alert/Alert.astro — headless primitive (see ../../README.md).
// Static, role="alert"; semantic tone via `variant`, exposed as `data-variant`.
import type { HTMLAttributes } from "astro/types";
type Props = HTMLAttributes<"div"> & {
variant?: "info" | "success" | "warning" | "error";
};
const { variant = "info", class: className, ...rest } = Astro.props;
---
<div class={className} role="alert" data-slot="alert" data-variant={variant} {...rest}>
<slot />
</div>
import Alert from "./Alert.astro";
export { Alert };
export default Alert;
What you get
The component source, copied into your project by npx astrocraft-ui add display/alert — no package dependency, no CSS to fight. Whatever the paid blocks compose, this is it.
