Flex

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

Import

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.

Usage

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.

Using the Spacer

As an alternative to Stack, you can combine Flex and Spacer to create stackable and responsive layouts.

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.

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

Since Spacer renders a div, any gap value provided to the parent is applied to both sides of this component, and therefore make the gap appear doubled when the spacer is completely collapsed.

The example below is not responsive on purpose as you might switch to a collapsed menu on mobile.
