### This is a base component. It should not be used in your feature code directly but as a "base" for other UI components
# HeaderBase
The `HeaderBase` component is a reusable UI component for displaying a header with optional startAccessory, children (title) and endAccessory content areas. It is designed to be flexible and customizable for various use cases to keep a visually balanced appearance.
<Canvas>
<Story id="components-componentlibrary-headerbase--default-story" />
</Canvas>
## Props
The `HeaderBase` accepts all props below as well as all [Box](/docs/components-ui-box--default-story#props) component props
<ArgsTable of={HeaderBase} />
### Children
Wrapping content in the `HeaderBase` component will be rendered in the center of the header.
Use the `childrenWrapperProps` prop to customize the wrapper element around the `children` content.
<Canvas>
<Story id="components-componentlibrary-headerbase--children" />
</Canvas>
```jsx
import { HeaderBase, Text } from '../../component-library';
import {
TEXT_ALIGN,
TextVariant,
} from '../../../helpers/constants/design-system';
<HeaderBase>
<Text variant={TextVariant.headingSm} textAlign={TEXT_ALIGN.CENTER}>
Title is sentence case no period
</Text>
</HeaderBase>;
```
### startAccessory
Using the `startAccessory` prop will render the content in the start (left) side of the header.
Use the `startAccessoryWrapperProps` prop to customize the wrapper element around the `startAccessory` content.
<Canvas>
<Story id="components-componentlibrary-headerbase--start-accessory" />
</Canvas>
```jsx
import {
HeaderBase,
Text,
ButtonIcon,
IconName,
} from '../../component-library';
import {
TEXT_ALIGN,
TextVariant,
} from '../../../helpers/constants/design-system';
<HeaderBase
startAccessory={
<ButtonIcon
size={BUTTON_ICON_SIZES.SM}
iconName={IconName.ArrowLeft}
ariaLabel="back"
/>
}
>
<Text variant={TextVariant.headingSm} textAlign={TEXT_ALIGN.CENTER}>
Title is sentence case no period
</Text>
</HeaderBase>;
```
### endAccessory
Using the `endAccessory` prop will render the content in the end (right) side of the header.
Use the `endAccessoryWrapperProps` prop to customize the wrapper element around the `endAccessory` content.
<Canvas>
<Story id="components-componentlibrary-headerbase--end-accessory" />
</Canvas>
```jsx
import {
ButtonIcon,
BUTTON_ICON_SIZES,
HeaderBase,
IconName,
Text,
} from '../../component-library';
import {
TEXT_ALIGN,
TextVariant,
} from '../../../helpers/constants/design-system';
<HeaderBase
endAccessory={
<ButtonIcon
size={BUTTON_ICON_SIZES.SM}
iconName={IconName.Close}
ariaLabel="close"
/>
}
>
<Text variant={TextVariant.headingSm} textAlign={TEXT_ALIGN.CENTER}>
Title is sentence case no period
</Text>
</HeaderBase>;
```
