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.

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

          
        
    
I'm an inline flexbox container!
        
            
            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.

Flex item 1
Flex item 2
Flex item 3
Flex item 1
Flex item 2
Flex item 3
        
            
            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.

Flex item 1
Flex item 2
Flex item 3
Flex item 1
Flex item 2
Flex item 3
        
            
            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>
                </>
              );
            }

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.

Flex item with a lot of content
Flex item

            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.

Flex item

Third flex item
        
            
            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.

Flex item

            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).

                  <div className="d-flex bg-body-tertiary mb-3">
                    <div className="me-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 bg-body-tertiary mb-3">
                    <div className="p-2">Flex item</div>
                    <div className="p-2">Flex item</div>
                    <div className="ms-auto p-2">Flex item</div>
                  </div>
                </>
              );
            }

          
        
    

With align-items

Vertically move one flex item to the top or bottom of a container by mixing align-items, flex-direction: column, and margin-top: auto or margin-bottom: auto.

                  </>
                );
              }
            
        
    

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.

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.

First flex item
Second flex item
Third flex item
        
            
            import React from 'react';

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.

Media object

Looking to replicate the media object component from Bootstrap 4? Recreate it in no time with a few flex utilities that allow even more flexibility and customization than before.

Generic placeholder image
This is some content from a media component. You can replace this with any content and adjust it as needed.
        
            
          import React from 'react';

          export default function App() {
            return (
              <div className="d-flex">
                <div className="flex-shrink-0">
                  <img src="https://mdbcdn.b-cdn.net/img/Photos/Others/placeholder1.webp" alt="Generic placeholder image">
                </div>
                <div className="flex-grow-1 ms-3">
                  This is some content from a media component. You can replace this with any content and adjust it as needed.
                </div>
              </div>
            );
          }
        
        
    

And say you want to vertically center the content next to the image:
