<ComponentPreview

  name="alert-dialog-basic"
  previewClassName="h-56"
/>

### Small

Use the `size="sm"` prop to make the alert dialog smaller.

<ComponentPreview
  styleName="base-nova"
  name="alert-dialog-small"

/>

### Media

Use the `AlertDialogMedia` component to add a media element such as an icon or image to the alert dialog.

<ComponentPreview
  styleName="base-nova"
  name="alert-dialog-media"
  previewClassName="h-56"
/>

### Small with Media

Use the `size="sm"` prop to make the alert dialog smaller and the `AlertDialogMedia` component to add a media element such as an icon or image to the alert dialog.

<ComponentPreview
  styleName="base-nova"
  name="alert-dialog-small-media"

| Prop   | Type                | Default     |
| ------ | ------------------- | ----------- |
| `size` | `"default" \| "sm"` | `"default"` |
