+
+# 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>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--size" />
+</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} />
+<ButtonBase size={SIZES.LG} />
+```
+
+### Block
+
+Use boolean `block` prop to quickly enable a full width block button
+
+<Canvas>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--block" />
+</Canvas>
+
+```jsx
+import { DISPLAY } from '../../../helpers/constants/design-system';
+import { ButtonBase } from '../ui/component-library';
+
+<ButtonBase>Default Button</ButtonBase>
+<ButtonBase block>Block Button</ButtonBase>
+```
+
+### As
+
+Use the `as` box prop to change the element of `ButtonBase`. Defaults to `button`.
+
+Button `as` options:
+
+- `button`
+- `a`
+
+<Canvas>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--as" />
+</Canvas>
+
+```jsx
+import { ButtonBase } from '../ui/component-library';
+
+
+<ButtonBase as="button">Button Element</ButtonBase>
+<ButtonBase as="a" href="#">
+  Anchor Element
+</ButtonBase>
+```
+
+### Disabled
+
+Use the boolean `disabled` prop to disable button
+
+<Canvas>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--disabled" />
+</Canvas>
+
+```jsx
+import { ButtonBase } from '../ui/component-library';
+
+<ButtonBase disabled>Disabled Button</ButtonBase>;
+```
+
+### Loading
+
+Use the boolean `loading` prop to set loading spinner
+
+<Canvas>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--loading" />
+</Canvas>
+
+```jsx
+import { ButtonBase } from '../ui/component-library';
+
+<ButtonBase loading>Loading Button</ButtonBase>;
+```
+
+### Icon
+
+Use the `icon` prop and the `ICON_NAMES` object from `./ui/components/component-library/icon` to select icon.
+
+<Canvas>
+  <Story id="ui-components-component-library-button-base-button-base-stories-js--icon" />
+</Canvas>
+
+```jsx
+import { ButtonBase } from '../ui/component-library';
+import { ICON_NAMES } from '../icon';
+
+<ButtonBase icon={ICON_NAMES.ADD_SQUARE_FILLED}>Button</ButtonBase>;
