Flex provides a layout container using CSS Flexbox.

The Flex primitive provides a Flexbox container with style display: flex. To learn how to use Flexbox CSS properties, see the following documentation:



Import the Flex primitive.

import { Flex, Button, useTheme } from '@aws-amplify/ui-react';

export const DefaultFlexExample = () => {
  const { tokens } = useTheme();

  return (
      <Button backgroundColor={[10]}>Button 1</Button>
      <Button backgroundColor={[20]}>Button 2</Button>
      <Button backgroundColor={[40]}>Button 3</Button>
