# Modal

Displays content in an overlay. Use to create a distraction-free experience such as a confirmation dialog or a settings panel.

## Properties

* accessibilityLabel

  string

  A label that describes the purpose of the modal. When set, it will be announced to users using assistive technologies and will provide them with more context.

  This overrides the `heading` prop for screen readers.

* heading

  string

  A title that describes the content of the Modal.

* id

  string

  A unique identifier for the element.

* padding

  'base' | 'none'

  Default: 'base'

  Adjust the padding around the Modal content.

  `base`: applies padding that is appropriate for the element.

  `none`: removes all padding from the element. This can be useful when elements inside the Modal need to span to the edge of the Modal. For example, a full-width image. In this case, rely on `Box` with a padding of 'base' to bring back the desired padding for the rest of the content.

* size

  'small' | 'large' | 'base' | 'small-100' | 'large-100' | 'max'

  Default: 'base'

  Adjust the size of the Modal.

  `max`: expands the Modal to its maximum size as defined by the host application, on both the horizontal and vertical axes.

## Events

* afterhide

  ((event: CallbackEventListener\<typeof tagName>) => void) | null

  Callback fired when the overlay is hidden **after** any animations to hide the overlay have finished.

* aftershow

  ((event: CallbackEventListener\<typeof tagName>) => void) | null

* hide

  ((event: CallbackEventListener\<typeof tagName>) => void) | null

  Callback fired after the overlay is hidden.

* show

  ((event: CallbackEventListener\<typeof tagName>) => void) | null

  Callback fired after the overlay is shown.

    (event: CallbackEvent<TTagName, TEvent>): void;
}) | null
```
