Box

Box is the most abstract layout component that allows to apply margin and padding properties according to the spacing system. By default, it renders a div element.

The Box component is useful because it helps with several common cases: create a layout that uses Forma 36 spacing system; and compose new component and allow to override element using the as property.

Import

import { Box } from '@contentful/f36-components';
// or
import { Box } from '@contentful/f36-core';
