Display property

Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.

Basic display values

The `display` property accepts a handful of values and we support many of them with utility classes. We purposefully don’t provide every value as a utility, so here’s what we support:

Classes	Use
`.d-none`	Used for object to hide on all viewports.
`.d-inline`	Used for object to behave like an inline object.
`.d-inline-block`	Used for object to behave like an inline-block object.
`.d-block`	Used for object to behave like an block object.
`.d-table`	Used for object to behave like `<table>` object.
`.d-table-cell`	Used for object to behave like `<td>` object.
`.d-flex`	Used for object as a block-level flex container.
`.d-inline-flex`	Used for object as an inline-level flex container.

Use above classes as per your requirements. For example, here’s how you could use the inline, block, or inline-block utilities.

d-inline


<div class="d-inline bg-secondary">d-inline</div>
<div class="d-inline bg-secondary">d-inline</div>

d-block


<span class="d-block bg-secondary">d-block</span>

d-inline-block


<div class="d-inline-block bg-secondary">d-inline-block</div>
<div class="d-inline-block bg-secondary">d-inline-block</div>

Responsive variations also exist for every single utility mentioned above.

.d-none
.d-inline
.d-inline-block
.d-block
.d-table
.d-table-cell
.d-flex
.d-inline-flex
.d-sm-none

.d-xl-block
.d-xl-table
.d-xl-table-cell
.d-xl-flex
.d-xl-inline-flex

Hiding Elements

For faster mobile-friendly development, use responsive display classes for showing and hiding elements by device. Avoid creating entirely different versions of the same site, instead hide element responsively for each screen size.

To hide elements simply use the .d-none class or one of the .d-{sm,md,lg,xl}-none classes for any responsive screen variation.

To show an element only on a given interval of screen sizes you can combine one .d-*-none class with a .d-*-* class, for example .d-none.d-md-block.d-xl-none will hide the element for all screen sizes except on medium and large devices.

Screen Size	Class
Hidden on all	`d-none`
Hidden only on xs	`d-none d-sm-block`
Hidden only on sm	`d-sm-none d-md-block`
Hidden only on md	`d-md-none d-lg-block`
Hidden only on lg	`d-lg-none d-xl-block`
Hidden only on xl	`d-xl-none`
Visible on all	`d-block`
Visible only on xs	`d-block d-sm-none`
Visible only on sm	`d-none d-sm-block d-md-none`
Visible only on md	`d-none d-md-block d-lg-none`
Visible only on lg	`d-none d-lg-block d-xl-none`
Visible only on xl	`d-none d-xl-block`

Display in print

Change the `display` value of elements when printing with our print display utilities.

Class	Print style
`.d-print-none`	Applies `display: none` to the element when printing
`.d-print-inline`	Applies `display: inline` to the element when printing
`.d-print-inline-block`	Applies `display: inline-block` to the element when printing
`.d-print-block`	Applies `display: block` to the element when printing

Embed

Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.

Rules are directly applied to <iframe>, <embed>, <video>, and <object> elements; optionally use an explicit descendant class .embed-responsive-item when you want to match the styling for other attributes.

Pro-Tip! You don’t need to include frameborder="0" in your <iframe>s as we override that for you.

Example

Wrap any embed like an `<iframe>` in a parent element with `.embed-responsive` and an aspect ratio. The `.embed-responsive-item` isn’t strictly required, but we encourage it.


<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/zpOULjyy-n8?rel=0" allowfullscreen></iframe>
</div>

Aspect ratios

Aspect ratios can be customized with modifier classes.


<!-- 21:9 aspect ratio -->
<div class="embed-responsive embed-responsive-21by9">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 1:1 aspect ratio -->
<div class="embed-responsive embed-responsive-1by1">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

Flex

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!


<div class="d-flex p-2">I'm a flexbox container!</div>

I'm an inline flexbox container!


<div class="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

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


<div class="d-flex flex-row">
  <div class="p-2">Flex item 1</div>
  <div class="p-2">Flex item 2</div>
  <div class="p-2">Flex item 3</div>
</div>
<div class="d-flex flex-row-reverse">
  <div class="p-2">Flex item 1</div>
  <div class="p-2">Flex item 2</div>
  <div class="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


<div class="d-flex flex-column">

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`, or `around`.

Flex item


<div class="d-flex justify-content-start">...</div>
<div class="d-flex justify-content-end">...</div>
<div class="d-flex justify-content-center">...</div>
<div class="d-flex justify-content-between">...</div>

.justify-content-xl-start
.justify-content-xl-end
.justify-content-xl-center
.justify-content-xl-between
.justify-content-xl-around

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).

Flex item


<div class="d-flex align-items-start">...</div>
<div class="d-flex align-items-end">...</div>
<div class="d-flex align-items-center">...</div>
<div class="d-flex align-items-baseline">...</div>
<div class="d-flex align-items-stretch">...</div>

Responsive variations also exist for align-items.

.align-items-start
.align-items-end
.align-items-center
.align-items-baseline
.align-items-stretch
.align-items-sm-start
.align-items-sm-end

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).

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 (`.me-auto`), and pushing two items to the left (`.ms-auto`).

Unfortunately, IE10 and IE11 do not properly support auto margins on flex items whose parent has a non-default justify-content value. See this StackOverflow answer for more details.

Flex item


<div class="d-flex">
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
</div>

<div class="d-flex">
  <div class="me-auto p-2">Flex item</div>
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
</div>

<div class="d-flex">
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
  <div class="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`.

Flex item


<div class="d-flex align-items-start flex-column" style="height: 200px;">
  <div class="mb-auto p-2">Flex item</div>
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
</div>

<div class="d-flex align-items-end flex-column" style="height: 200px;">
  <div class="p-2">Flex item</div>
  <div class="p-2">Flex item</div>
  <div class="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`.

Flex item


<div class="d-flex flex-nowrap">
  ...
</div>

Flex item


<div class="d-flex flex-wrap">
  ...
</div>

Flex item


<div class="d-flex flex-wrap-reverse">
  ...
</div>

Responsive variations also exist for flex-wrap.

.flex-lg-wrap
.flex-lg-wrap-reverse
.flex-xl-nowrap
.flex-xl-wrap
.flex-xl-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 (e.g., `5`), add custom CSS for any additional values needed.

First flex item

Second flex item

Third flex item


<div class="d-flex flex-nowrap">
  <div class="order-3 p-2">First flex item</div>
  <div class="order-2 p-2">Second flex item</div>
  <div class="order-1 p-2">Third flex item</div>

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.

Flex item


<div class="d-flex align-content-start flex-wrap">
  ...
</div>

Flex item


<div class="d-flex align-content-end flex-wrap">

Image replacement

Swap text for background images with the image replacement class.

Utilize the .text-hide class or mixin to help replace an element’s text content with a background image.


<h1 class="text-hide">Custom heading</h1>

Use the .text-hide class to maintain the accessibility and SEO benefits of heading tags, but want to utilize a background-image instead of text.

Bootstrap


<h1 class="text-hide my-2" style="background-image: url('../assets/images/logo-icon.png'); width: 30px; height: 26px;">Bootstrap</h1>

Position

Use these shorthand utilities for quickly configuring the position of an element.

Classes	Use
`.position-fixed`	Changes object's position to fixed.
`.position-relative`	Changes object's position to relative.
`.position-absolute`	Changes object's position to absolute.
`.position-static`	Changes object's position to static.
`.position-sticky`	Changes object's position to static.

Fixed top

Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.


<div class="fixed-top">...</div>

Fixed bottom

Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.


<div class="fixed-bottom">...</div>

Sticky top

Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The `.sticky-top` utility uses CSS’s `position: sticky`, which isn’t fully supported in all browsers.

Microsoft Edge and IE11 will render position: sticky as position: relative. As such, we wrap the styles in a @supports query, limiting the stickiness to only browsers that properly can render it.


<div class="sticky-top">...</div>

Screenreaders

Use screenreader utilities to hide elements on all devices except screen readers.

Hide an element to all devices except screen readers with .sr-only. Combine .sr-only with .sr-only-focusable to show the element again when it’s focused (e.g. by a keyboard-only user). Can also be used as mixins.


<a class="sr-only sr-only-focusable" href="#content">Skip to main content</a>

Sizing

Easily make an element as wide or as tall (relative to its parent) with our width and height utilities.

Width and height utilities are generated from the $sizes Sass map in _variables.scss. Includes support for 25%,50%, 75%, and 100% by default. Modify those values as you need to generate different utilities here.

Width 25%

Width 50%

Width 75%

Width 100%


<div class="w-25 p-3" style="background-color: #eee;">Width 25%</div>
<div class="w-50 p-3" style="background-color: #eee;">Width 50%</div>
<div class="w-75 p-3" style="background-color: #eee;">Width 75%</div>
<div class="w-100 p-3" style="background-color: #eee;">Width 100%</div>

Height 25%

Height 50%

Height 75%

Height 100%


<div style="height: 100px; background-color: rgba(255,0,0,0.1);">
  <div class="h-25 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 25%</div>
  <div class="h-50 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 50%</div>
  <div class="h-75 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 75%</div>
  <div class="h-100 d-inline-block" style="width: 120px; background-color: rgba(0,0,255,.1)">Height 100%</div>
</div>

You can also use max-width: 100%; and max-height: 100%; utilities as needed.


<img class="mw-100" src="..." alt="Max-width 100%">

Max-height 100%


<div style="height: 100px; background-color: rgba(255,0,0,0.1);">
  <div class="mh-100" style="width: 100px; height: 200px; background-color: rgba(0,0,255,0.1);">Max-height 100%</div>
</div>

Fixed Width

Add one of these to class to set fixed width of the content.

Classes	Description
`.width-{size}`	Set content fixed width in pixel of selected size where size can be 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750 and 800. i.e `.width-50`
`.width-{size}-per`	Set content fixed width in percentage of selected size where size can be 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75% and 80%. i.e `.width-5-per`

Fixed Height

Add one of these to class to set fixed height of the content.

Classes	Description
`.height-{size}`	Set content fixed height in pixel of selected size where size can be 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750 and 800. i.e `.height-50`

Spacing

Bootstrap includes a wide range of shorthand responsive margin and padding utility classes to modify an element's appearance.

How it works

Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem to 3rem.

Notation

Spacing utilities that apply to all breakpoints, from xs to xl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0 and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation. The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Where property is one of:

m - for classes that set margin
p - for classes that set padding

Wheresides is one of:

t - for classes that set margin-top or padding-top
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
auto - for classes that set the margin to auto

(You can add more sizes by adding entries to the $spacers Sass map variable.)

Horizontal centering

Additionally, Bootstrap also includes an `.mx-auto` class for horizontally centering fixed-width block level content—that is, content that has `display: block` and a `width` set—by setting the horizontal margins to `auto`.

Centered element


<div class="mx-auto" style="width: 200px;">
    Centered element
</div>

Vertical alignment

Easily change the vertical alignment of inline, inline-block, inline-table, and table cell elements.

Change the alignment of elements with the vertical-alignment utilities. Please note that vertical-align only affects inline, inline-block, inline-table, and table cell elements.

Choose from .align-baseline, .align-top, .align-middle, .align-bottom, .align-text-bottom, and .align-text-top as needed.

baseline top middle bottom text-top text-bottom

Classes	Description
`.align-top`	Changes element's vertical alignment to top.
`.align-middle`	Changes element's vertical alignment to middle.
`.align-bottom`	Changes element's vertical alignment to bottom.
`.align-baseline`	Changes element's vertical alignment to baseline.
`.align-text-top`	Top of the element is aligned with the top of the parent element's font.
`.align-text-bottom`	The bottom of the element is aligned with the bottom of the parent element's font.

With table cells:

baseline

top

middle

bottom

text-top

text-bottom


<table style="height: 100px;">
  <tbody>
    <tr>
      <td class="align-baseline">baseline</td>
      <td class="align-top">top</td>
      <td class="align-middle">middle</td>
      <td class="align-bottom">bottom</td>
      <td class="align-text-top">text-top</td>
      <td class="align-text-bottom">text-bottom</td>
    </tr>
  </tbody>
</table>

Visibility

Control the visibility, without modifying the display, of elements with visibility utilities.

Set the visibility of elements with our visibility utilities. These do not modify the display value at all and are helpful for hiding content from most users, but still keeping them for screen readers.

Apply .visible or .invisible as needed.


<div class="visible">...</div>
<div class="invisible">...</div>

Bootstrap Classes

Borders

Use border utilities to quickly style the border and border-radius of an element. Great for images, buttons, or any other element.

Additive border

Use of below classes as per your requiements, which side you want border.

Subtractive border

Use of below classes as per your requiements, which side you don't want to add border.

Border color

When you want add color in the border you can choose any of the below classes.

Border-radius

Use to give rounded corner to the object.

Close icon

Use a generic close icon for dismissing content like modals and alerts.

Display property

Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.

Basic display values

The display property accepts a handful of values and we support many of them with utility classes. We purposefully don’t provide every value as a utility, so here’s what we support:

Hiding Elements

Display in print

Change the display value of elements when printing with our print display utilities.

Embed

Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.

Example

Wrap any embed like an <iframe> in a parent element with .embed-responsive and an aspect ratio. The .embed-responsive-item isn’t strictly required, but we encourage it.

Aspect ratios

Aspect ratios can be customized with modifier classes.

Flex

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.

Direction

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, or around.

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).

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).

The `display` property accepts a handful of values and we support many of them with utility classes. We purposefully don’t provide every value as a utility, so here’s what we support:

Change the `display` value of elements when printing with our print display utilities.

Wrap any embed like an `<iframe>` in a parent element with `.embed-responsive` and an aspect ratio. The `.embed-responsive-item` isn’t strictly required, but we encourage it.

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.

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`, or `around`.

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).

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).

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 (`.me-auto`), and pushing two items to the left (`.ms-auto`).

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`.

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`.

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 (e.g., `5`), add custom CSS for any additional values needed.

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.

Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The `.sticky-top` utility uses CSS’s `position: sticky`, which isn’t fully supported in all browsers.
