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

# BannerBase

`BannerBase` serves as a base for all banner variants. It contains standard props such as information and related actions.

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--default-story" />
</Canvas>

## Props

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

<ArgsTable of={BannerBase} />

### Title

Use the `title` prop to pass a string that is sentence case no period. Use the `titleProps` prop to pass additional props to the `Text` component.

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--title" />
</Canvas>

```jsx
import { BannerBase } from '../../component-library';

<BannerBase title="Title is sentence case no period">
  Pass only a string through the title prop
</BannerBase>;
```

### Description

The `description` is the content area of the `BannerBase` that must be a string. Description shouldn't repeat title and only 1-3 lines.

If content requires more than a string, see `children` prop below.

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--description" />
</Canvas>

```jsx
import { BannerBase } from '../../component-library';

<BannerBase
  title="Description vs children"
  description="Pass only a string through the description prop or you can use children if the contents require more"
/>;
```

### Children

The `children` prop is an alternative to `description` for `BannerBase` when more than a string is needed. Children content shouldn't repeat title and only 1-3 lines.

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--children" />
</Canvas>

```jsx
import { Size } from '../../../helpers/constants/design-system';
import { BannerBase } from '../../component-library';

<BannerBase>
  {`Description shouldn't repeat title. 1-3 lines. Can contain a `}
  <ButtonLink size={Size.inherit} href="https://metamask.io/" target="_blank">
    hyperlink.
  </ButtonLink>
</BannerBase>;
```

### Action Button Label, onClick, & Props

Use the `actionButtonLabel` prop to pass text, `actionButtonOnClick` prop to pass an onClick handler, and `actionButtonProps` prop to pass an object of [ButtonLink props](/docs/components-componentlibrary-buttonlink--default-story) for the action

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--action-button" />
</Canvas>

```jsx
import { BannerBase, ICON_NAMES } from '../../component-library';

<BannerBase
  title="Action prop demo"
  actionButtonLabel="Action"
  actionButtonProps={{
    iconName: ICON_NAMES.ARROW_2_RIGHT,
    iconPositionRight: true,
  }}
  actionButtonOnClick={() => console.log('ButtonLink actionButtonOnClick demo')}
>
  Use actionButtonLabel for action text, actionButtonOnClick for the onClick
  handler, and actionButtonProps to pass any ButtonLink prop types such as
  iconName
</BannerBase>;
```

### On Close

Use the `onClose` prop to pass a function to the close button. The close button will appear when this prop is used.

Additional props can be passed to the close button with `closeButtonProps`

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--on-close" />
</Canvas>

```jsx
import { BannerBase } from '../../component-library';

<BannerBase
  title="onClose demo"
  onClose={() => console.log('close button clicked')}
>
  Click the close button icon to hide this notifcation
</BannerBase>;
```

### Start Accessory

Use the `startAccessory` prop to add components such as icons or fox image to the start (default: left) of the `BannerBase` content

<Canvas style={{ background: 'var(--color-background-alternative)' }}>
  <Story id="components-componentlibrary-bannerbase--start-accessory" />
</Canvas>

```jsx
import { Size } from '../../../helpers/constants/design-system';
import { BannerBase, Icon, ICON_NAMES } from '../../component-library';

<BannerBase
  title="Start accessory demo"
  startAccessory={<Icon name={ICON_NAMES.INFO} size={Size.LG} />}
>
  The info icon on the left is passed through the startAccessory prop
</BannerBase>;
```
