Flex is Box with display: flex and comes with helpful style shorthand. It renders a div element.


import { Flex, Spacer } from "@chakra-ui/react"
  • Flex: A Box with display: flex.
  • Spacer: Creates an adjustable, empty space that can be used to tune the spacing between child elements within Flex.


Using the Flex components, here are some helpful shorthand props:

  • flexDirection is direction
  • flexWrap is wrap
  • flexBasis is basis
  • flexGrow is grow
  • flexShrink is shrink
  • alignItems is align
  • justifyContent is justify

While you can pass the verbose props, using the shorthand can save you some time.

Flex and Spacer vs Grid vs Stack#

The Flex and Spacer components, Grid and HStack treat children of different widths differently.

  • In HStack, the children will have equal spacing between them but they won't span the entire width of the container.
  • In Grid, the starting points of the children will be equally spaced but the gaps between them will not be equal.
  • With Flex and Spacer, the children will span the entire width of the container and also have equal spacing between them.

Flex and Spacer: Full width, equal Spacing

Grid: The children start at the beginning, the 1/3 mark and 2/3 mark

HStack: The children have equal spacing but don't span the whole container

Editable Example

A good use case for Spacer is to create a navbar with a signup/login button aligned to the right.
