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>

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>

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>
</>
);
}

.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 bg-body-tertiary 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 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
.
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
.flex-wrap
.flex-wrap-reverse
.flex-sm-nowrap
.flex-sm-wrap
.flex-sm-wrap-reverse
.flex-md-nowrap

.flex-lg-wrap-reverse
.flex-xl-nowrap
.flex-xl-wrap
.flex-xl-wrap-reverse
.flex-xxl-nowrap
.flex-xxl-wrap
.flex-xxl-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.
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

Additionally there are also responsive .order-first
and
.order-last
classes that change the order
of an element by applying
order: -1
and order: 6
, respectively.
.order-first
.order-last
.order-sm-first
.order-sm-last
.order-md-first
.order-md-last
.order-lg-first

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.
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-start flex-wrap">
...
</div>
);
}
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-end flex-wrap">...</div>
);
}
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-center flex-wrap">...</div>
);
}
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-between flex-wrap">...</div>
);
}
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-around flex-wrap">...</div>
);
}
import React from 'react';
export default function App() {
return (
<div className="d-flex align-content-stretch flex-wrap">...</div>
);
}
Responsive variations also exist for align-content
.

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.
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:
import React from 'react';
export default function App() {
return (
<div className="d-flex align-items-center">
<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>
);
}
