Flexbox

React Bootstrap 5 Flexbox component

Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities. For more complex implementations, custom CSS may be necessary.

Enable flex behaviors

Apply display utilities to create a flexbox container and transform direct children elements into flex items. Flex containers and items are able to be modified further with additional flex properties.

        
            
            import React from "react";
            
            export default function App(){
              return (
                <div className="d-flex p-2">I'm a flexbox container!</div>
              );
            }

          
        
    

        
            
            import React from "react";
            
            export default function App(){
              return (
                <div className="d-inline-flex p-2">I'm an inline flexbox container!</div>
              );
            }

          
        
    

Responsive variations also exist for .d-flex and .d-inline-flex.

• .d-flex
• .d-inline-flex
• .d-sm-flex
• .d-sm-inline-flex
• .d-md-flex
• .d-md-inline-flex
• .d-lg-flex
• .d-lg-inline-flex
• .d-xl-flex
• .d-xl-inline-flex
• .d-xxl-flex
• .d-xxl-inline-flex

Direction

Set the direction of flex items in a flex container with direction utilities. In most cases you can omit the horizontal class here as the browser default is row. However, you may encounter situations where you needed to explicitly set this value (like responsive layouts).

Use .flex-row to set a horizontal direction (the browser default), or .flex-row-reverse to start the horizontal direction from the opposite side.

        
            
            import React from "react";
            
            export default function App(){
              return (
                <>
                  <div className="d-flex flex-row mb-3">
                    <div className="p-2">Flex item 1</div>
                    <div className="p-2">Flex item 2</div>
                    <div className="p-2">Flex item 3</div>
                  </div>
                  <div className="d-flex flex-row-reverse">
                    <div className="p-2">Flex item 1</div>
                    <div className="p-2">Flex item 2</div>
                    <div className="p-2">Flex item 3</div>
                  </div>
                </>
              );
            }
          
        
    

Use .flex-column to set a vertical direction, or .flex-column-reverse to start the vertical direction from the opposite side.

        
            
            import React from "react";
            
            export default function App(){
              return (
                <>
                  <div className="d-flex flex-column mb-3">
                    <div className="p-2">Flex item 1</div>
                    <div className="p-2">Flex item 2</div>
                    <div className="p-2">Flex item 3</div>
                  </div>
                  <div className="d-flex flex-column-reverse">
                    <div className="p-2">Flex item 1</div>
                    <div className="p-2">Flex item 2</div>
                    <div className="p-2">Flex item 3</div>
                  </div>
                </>
              );
            }

Justify content

Use justify-content utilities on flexbox containers to change the alignment of flex items on the main axis (the x-axis to start, y-axis if flex-direction: column). Choose from start (browser default), end, center, between, around, or evenly.

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className='d-flex justify-content-start'>...</div>
                  <div className='d-flex justify-content-end'>...</div>
                  <div className='d-flex justify-content-center'>...</div>
                  <div className='d-flex justify-content-between'>...</div>
                  <div className='d-flex justify-content-around'>...</div>
                  <div className='d-flex justify-content-evenly'>...</div>
                </>
              );

Align items

Use align-items utilities on flexbox containers to change the alignment of flex items on the cross axis (the y-axis to start, x-axis if flex-direction: column). Choose from start, end, center, baseline, or stretch (browser default).

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className="d-flex align-items-start">...</div>
                  <div className="d-flex align-items-end">...</div>
                  <div className="d-flex align-items-center">...</div>
                  <div className="d-flex align-items-baseline">...</div>
                  <div className="d-flex align-items-stretch">...</div>
                </>
              );
            }

• .align-items-xxl-baseline
• .align-items-xxl-stretch

Align self

Use align-self utilities on flexbox items to individually change their alignment on the cross axis (the y-axis to start, x-axis if flex-direction: column). Choose from the same options as align-items: start, end, center, baseline, or stretch (browser default).

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className="align-self-start">Aligned flex item</div>
                  <div className="align-self-end">Aligned flex item</div>
                  <div className="align-self-center">Aligned flex item</div>
                  <div className="align-self-baseline">Aligned flex item</div>
                  <div className="align-self-stretch">Aligned flex item</div>
                </>
              );
            }

          
        
    

Responsive variations also exist for align-self.

• .align-self-start

• .align-self-xxl-start
• .align-self-xxl-end
• .align-self-xxl-center
• .align-self-xxl-baseline
• .align-self-xxl-stretch

Fill

Use the .flex-fill class on a series of sibling elements to force them into widths equal to their content (or equal widths if their content does not surpass their border-boxes) while taking up all available horizontal space.

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className="d-flex">
                    <div className="p-2 flex-fill">Flex item with a lot of content</div>
                    <div className="p-2 flex-fill">Flex item</div>
                    <div className="p-2 flex-fill">Flex item</div>
                  </div>
                </>
              );
            }

          
        
    

Responsive variations also exist for flex-fill.

• .flex-fill
• .flex-sm-fill
• .flex-md-fill
• .flex-lg-fill
• .flex-xl-fill
• .flex-xxl-fill

Grow and shrink

Use .flex-grow-* utilities to toggle a flex item’s ability to grow to fill available space. In the example below, the .flex-grow-1 elements uses all available space it can, while allowing the remaining two flex items their necessary space.

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className="d-flex">
                    <div className="p-2 flex-grow-1">Flex item</div>
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Third flex item</div>
                  </div>
                </>
              );
            }

          
        
    

Use .flex-shrink-* utilities to toggle a flex item’s ability to shrink if necessary. In the example below, the second flex item with .flex-shrink-1 is forced to wrap its contents to a new line, “shrinking” to allow more space for the previous flex item with .w-100.

        
            
            import React from 'react';

            export default function App() {
              return (
                <div className="d-flex">
                  <div className="p-2 w-100">Flex item</div>
                  <div className="p-2 flex-shrink-1">Flex item</div>
                </div>
              );
            }
          
        
    

Responsive variations also exist for flex-grow and flex-shrink.

• .flex-{grow|shrink}-0
• .flex-{grow|shrink}-1
• .flex-sm-{grow|shrink}-0
• .flex-sm-{grow|shrink}-1
• .flex-md-{grow|shrink}-0
• .flex-md-{grow|shrink}-1
• .flex-lg-{grow|shrink}-0
• .flex-lg-{grow|shrink}-1
• .flex-xl-{grow|shrink}-0
• .flex-xl-{grow|shrink}-1
• .flex-xxl-{grow|shrink}-0
• .flex-xxl-{grow|shrink}-1

Auto margins

Flexbox can do some pretty awesome things when you mix flex alignments with auto margins. Shown below are three examples of controlling flex items via auto margins: default (no auto margin), pushing two items to the right (.mr-auto), and pushing two items to the left (.ml-auto).

        
            
            import React from 'react';

            export default function App() {
              return (
                <>
                  <div className="d-flex mb-3">
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                  </div>
          
                  <div className="d-flex mb-3">
                    <div className="mr-auto p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                  </div>
          
                  <div className="d-flex mb-3">
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                    <div className="ml-auto p-2">Flex item</div>
                  </div>
                </>
              );
            }

          
        
    

        
            
              import React from 'react';

              export default function App() {
                return (
                  <>
                    <div classaName="d-flex align-items-start flex-column mb-3" style="height: 200px;">
                      <div classaName="mb-auto p-2">Flex item</div>
                      <div classaName="p-2">Flex item</div>
                      <div classaName="p-2">Flex item</div>
                    </div>
                    <div classaName="d-flex align-items-end flex-column mb-3" style="height: 200px;">
                      <div classaName="p-2">Flex item</div>
                      <div classaName="p-2">Flex item</div>
                      <div classaName="mt-auto p-2">Flex item</div>
                    </div>
                  </>
                );
              }
            
        
    

Wrap

Change how flex items wrap in a flex container. Choose from no wrapping at all (the browser default) with .flex-nowrap, wrapping with .flex-wrap, or reverse wrapping with .flex-wrap-reverse.

        
            
            import React from 'react';

            export default function App() {
              return (
                <div className="d-flex flex-nowrap">
                  ...
                </div>
              );
            }
          
        
    

        
            
            import React from 'react';

            export default function App() {
              return (
                <div className="d-flex flex-wrap">
                  ...
                </div>
              );
            }
          
        
    

        
            
            import React from 'react';

            export default function App() {
              return (
                <div className="d-flex flex-wrap-reverse">
                  ...
                </div>
              );
            }
          
        
    

Responsive variations also exist for flex-wrap.

• .flex-nowrap

Order

Change the visual order of specific flex items with a handful of order utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order. As order takes any integer value from 0 to 5, add custom CSS for any additional values needed.

        
            
            import React from 'react';

            export default function App() {
              return (
                <div className="d-flex flex-nowrap">
                  <div className="order-3 p-2">First flex item</div>
                  <div className="order-2 p-2">Second flex item</div>
                  <div className="order-1 p-2">Third flex item</div>
                </div>
              );
            }
          
        
    

Responsive variations also exist for order.

• .order-0
• .order-1
• .order-2
• .order-3
• .order-4
• .order-5
• .order-sm-0
• .order-sm-1
• .order-sm-2

Align content

Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we’ve enforced flex-wrap: wrap and increased the number of flex items.

Heads up! This property has no effect on single rows of flex items.
