### 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>
<Story id="components-componentlibrary-bannerbase--default-story" />
</Canvas>
## 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>
<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>
<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>
<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>
<Story id="components-componentlibrary-bannerbase--action-button" />
</Canvas>
```jsx
import { BannerBase, IconName } from '../../component-library';
<BannerBase
title="Action prop demo"
actionButtonLabel="Action"
actionButtonProps={{
endIconName: IconName.Arrow2Right,
}}
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>
<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>
<Story id="components-componentlibrary-bannerbase--start-accessory" />
</Canvas>
```jsx
import { Size } from '../../../helpers/constants/design-system';
import { BannerBase } from '../../component-library';
import { Icon, IconName } from '../../component-library';
<BannerBase
title="Start accessory demo"
startAccessory={<Icon name={IconName.Info} size={IconSize.Lg} />}
>
The info icon on the left is passed through the startAccessory prop
</BannerBase>;
```
