}API
Spinner
| Prop | Type | Default | Description |
|---|---|---|---|
as | ElementType | "div" | Changes the rendered root tag, for example as="span". |
className | string | — | Class names are forwarded to the root element for client-side styling. |
align | "center" | "fixed" | "absolute" | — | Positions the spinner in normal flow, fixed to the viewport, or absolutely. |
children | ReactNode | — | Visible content rendered alongside the status region's accessible name. |
value | number | — | Fixed 0–100 percentage. Replaces the animation with a static arc and switches the role to progressbar. |
delay | number | 0 | Milliseconds to wait before the spinner appears, applied in CSS so it needs no JavaScript. |
label | string | "Loading" | Accessible name announced by the status region. |
showLabel | boolean | false | Renders the visible label as a [data-part="label"] part. |
size | "small" | "default" | "large" | "default" | Controls the CSS-only spinner diameter. |
render | ReactElement | ((props, state) => ReactElement) | — | Replace the rendered element while keeping behavior and accessibility wiring. |
Keyboard
| Key | Action |
|---|
Accessibility
Uses a role="status" live region with an aria-label. The visual indicator is CSS-only and does not render SVG.
