### This is a base component. It should not be used in your feature code directly but as a "base" for other UI components

# ButtonBase

The `ButtonBase` is the base component for buttons.

<Canvas>
  <Story id="ui-components-component-library-button-base-button-base-stories-js--default-story" />
</Canvas>

## Props

The `ButtonBase` accepts all props below as well as all [Box](/docs/ui-components-ui-box-box-stories-js--default-story#props) component props

<ArgsTable of={ButtonBase} />

### Size

Use the `size` prop and the `SIZES` object from `./ui/helpers/constants/design-system.js`
to change the size of `ButtonBase`. Defaults to `SIZES.MD`

Optional: `BUTTON_SIZES` from `./button-base` object can be used instead of `SIZES`.

Possible sizes include:

- `SIZES.AUTO` inherits the font-size of the parent element.
- `SIZES.SM` 32px
- `SIZES.MD` 40px
- `SIZES.LG` 48px

</Canvas>

```jsx
import { SIZES } from '../../../helpers/constants/design-system';
import { ButtonBase } from '../ui/component-library';

<ButtonBase size={SIZES.AUTO} />
<ButtonBase size={SIZES.SM} />
<ButtonBase size={SIZES.MD} />
