Box component for Stripe Apps

Use boxes to wrap other components and add custom styles and layouts.

SDK version

To add the Box component to your app:

import {Box} from '@stripe/ui-extension-sdk/ui';

Boxes are block-level elements, equivalent to a div HTML element. They support custom styles. If you want to render or style inline elements, see the Inline component.

Loading example...

<Box

    padding: 'xxlarge',
    color: 'secondary',

Nesting boxes

For some components, you can use a Box to manage the layout and spacing of their children. For example, nest a Box inside an AccordionItem to add padding:

Loading example...

<Box css={{backgroundColor: 'surface'}}>
  <Accordion>
    <AccordionItem title="Apples">
      <Box css={{padding: 'xlarge'}}>Accordion contents</Box>
    </AccordionItem>
    <AccordionItem title="Bananas">
      <Box css={{padding: 'xlarge'}}>Accordion contents</Box>
    </AccordionItem>
    <AccordionItem title="Peaches" subtitle="A subtitle can be provided">
      <Box css={{padding: 'xlarge'}}>Accordion contents</Box>
    </AccordionItem>
  </Accordion>
</Box>
