Modal

Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.

How it works

Before getting started with Bootstrap’s modal component, be sure to read the following as our menu options have recently changed.

Modals are built with HTML, CSS, and JavaScript. They’re positioned over everything else in the document and remove scroll from the <body> so that modal content scrolls instead.
Clicking on the modal “backdrop” will automatically close the modal.
Bootstrap only supports one modal window at a time. Nested modals aren’t supported as we believe them to be poor user experiences.
Modals use position: fixed, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You’ll likely run into issues when nesting a .modal within another fixed element.
Once again, due to position: fixed, there are some caveats with using modals on mobile devices. See our browser support docs for details.
Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:

var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
  myInput.focus()
})

The animation effect of this component is dependent on the prefers-reduced-motion media query. See the reduced motion section of our accessibility documentation.

Keep reading for demos and usage guidelines.

Examples

Below is a static modal example (meaning its position and display have been overridden). Included are the modal header, modal body (required for padding), and modal footer (optional). We ask that you include modal headers with dismiss actions whenever possible, or provide another explicit dismiss action.

<div class="modal" tabindex="-1">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <p>Modal body text goes here.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Live demo

Toggle a working modal demo by clicking the button below. It will slide down and fade in from the top of the page.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Static backdrop

When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">
  Launch static backdrop modal
</button>

<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="staticBackdropLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Understood</button>
      </div>
    </div>
  </div>
</div>

Scrolling long content

When modals become too long for the user’s viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

What follows is just some placeholder text for this modal dialog. Sipping on Rosé, Silver Lake sun, coming up all lazy. It’s in the palm of your hand now baby. So we hit the boulevard. So make a wish, I'll make it like your birthday everyday. Do you ever feel already buried deep six feet under? It's time to bring out the big balloons. You could've been the greatest. Passport stamps, she's cosmopolitan. Your kiss is cosmic, every move is magic.

We're living the life. We're doing it right. Open up your heart. I was tryna hit it and quit it. Her love is like a drug. Always leaves a trail of stardust. The girl's a freak, she drive a jeep in Laguna Beach. Fine, fresh, fierce, we got it on lock. All my girls vintage Chanel baby.

Before you met me I was alright but things were kinda heavy. Peach-pink lips, yeah, everybody stares. This is no big deal. Calling out my name. I could have rewrite your addiction. She's got that, je ne sais quoi, you know it. Heavy is the head that wears the crown. 'Cause, baby, you're a firework. Like thunder gonna shake the ground.

Just own the night like the 4th of July! I’m gon’ put her in a coma. What you're waiting for, it's time for you to show it off. Can't replace you with a million rings. You open my eyes and I'm ready to go, lead me into the light. And here you are. I’m gon’ put her in a coma. Come on, let your colours burst. So cover your eyes, I have a surprise. As I march alone to a different beat. Glitter all over the room pink flamingos in the pool.

You just gotta ignite the light and let it shine! Come just as you are to me. Just own the night like the 4th of July. Infect me with your love and fill me with your poison. Come just as you are to me. End of the rainbow looking treasure.

I can't sleep let's run away and don't ever look back, don't ever look back. I can't sleep let's run away and don't ever look back, don't ever look back. Yes, we make angels cry, raining down on earth from up above. I'm walking on air (tonight). Let you put your hands on me in my skin-tight jeans. Stinging like a bee I earned my stripes. I went from zero, to my own hero. Even brighter than the moon, moon, moon. Make 'em go, 'Aah, aah, aah' as you shoot across the sky-y-y! Why don't you let me stop by?

Boom, boom, boom. Never made me blink one time. Yeah, you're lucky if you're on her plane. Talk about our future like we had a clue. Oh my God no exaggeration. You're original, cannot be replaced. The girl's a freak, she drive a jeep in Laguna Beach. It's no big deal, it's no big deal, it's no big deal. In another life I would make you stay. I'm ma get your heart racing in my skin-tight jeans. I wanna walk on your wave length and be there when you vibrate Never made me blink one time.

We'd keep all our promises be us against the world. If you get the chance you better keep her. It's time to bring out the big, big, big, big, big, big balloons. I hope you got a healthy appetite. Don't let the greatness get you down, oh, oh yeah. Yeah, she's footloose and so fancy free. I want the jaw droppin', eye poppin', head turnin', body shockin'. End of the rainbow looking treasure.

You can also create a scrollable modal that allows scroll the modal body by adding .modal-dialog-scrollable to .modal-dialog.

What follows is just some placeholder text for this modal dialog. You just gotta ignite the light and let it shine! Come just as you are to me. Just own the night like the 4th of July. Infect me with your love and fill me with your poison. Come just as you are to me. End of the rainbow looking treasure.

We'd keep all our promises be us against the world. In another life I would be your girl. We can dance, until we die, you and I, will be young forever. And on my 18th Birthday we got matching tattoos. So open up your heart and just let it begin. 'Cause she's the muse and the artist. She eats your heart out. Like Jeffrey Dahmer (woo). Pop your confetti. (This is how we do) I know one spark will shock the world, yeah yeah. If you only knew what the future holds.

Sipping on Rosé, Silver Lake sun, coming up all lazy. It’s in the palm of your hand now baby. So we hit the boulevard. So make a wish, I'll make it like your birthday everyday. Do you ever feel already buried deep six feet under? It's time to bring out the big balloons. You could've been the greatest. Passport stamps, she's cosmopolitan. Your kiss is cosmic, every move is magic.

<!-- Scrollable modal -->
<div class="modal-dialog modal-dialog-scrollable">
  ...
</div>

Vertically centered

Add .modal-dialog-centered to .modal-dialog to vertically center the modal.

<!-- Vertically centered modal -->
<div class="modal-dialog modal-dialog-centered">
  ...
</div>

<!-- Vertically centered scrollable modal -->
<div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
  ...
</div>

Tooltips and popovers

Tooltips and popovers can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.

<div class="modal-body">
  <h5>Popover in a modal</h5>
  <p>This <a href="#" role="button" class="btn btn-secondary popover-test" title="Popover title" data-bs-content="Popover body content is set in this attribute.">button</a> triggers a popover on click.</p>
  <hr>
  <h5>Tooltips in a modal</h5>
  <p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> have tooltips on hover.</p>
</div>

Using the grid

Utilize the Bootstrap grid system within a modal by nesting .container-fluid within the .modal-body. Then, use the normal grid system classes as you would anywhere else.

<div class="modal-body">
  <div class="container-fluid">
    <div class="row">
      <div class="col-md-4">.col-md-4</div>
      <div class="col-md-4 ms-auto">.col-md-4 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-md-3 ms-auto">.col-md-3 .ms-auto</div>
      <div class="col-md-2 ms-auto">.col-md-2 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-md-6 ms-auto">.col-md-6 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-sm-9">
        Level 1: .col-sm-9
        <div class="row">
          <div class="col-8 col-sm-6">
            Level 2: .col-8 .col-sm-6
          </div>
          <div class="col-4 col-sm-6">
            Level 2: .col-4 .col-sm-6
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

Have a bunch of buttons that all trigger the same modal with slightly different contents? Use event.relatedTarget and HTML data-bs-* attributes to vary the contents of the modal depending on which button was clicked.

Below is a live demo followed by example HTML and JavaScript. For more information, read the modal events docs for details on relatedTarget.

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@getbootstrap">Open modal for @getbootstrap</button>

<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">New message</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <form>
          <div class="mb-3">
            <label for="recipient-name" class="col-form-label">Recipient:</label>
            <input type="text" class="form-control" id="recipient-name">
          </div>
          <div class="mb-3">
            <label for="message-text" class="col-form-label">Message:</label>
            <textarea class="form-control" id="message-text"></textarea>
          </div>
        </form>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Send message</button>
      </div>
    </div>
  </div>
</div>

var exampleModal = document.getElementById('exampleModal')
exampleModal.addEventListener('show.bs.modal', function (event) {
  // Button that triggered the modal
  var button = event.relatedTarget
  // Extract info from data-bs-* attributes
  var recipient = button.getAttribute('data-bs-whatever')
  // If necessary, you could initiate an AJAX request here
  // and then do the updating in a callback.
  //
  // Update the modal's content.
  var modalTitle = exampleModal.querySelector('.modal-title')
  var modalBodyInput = exampleModal.querySelector('.modal-body input')

  modalTitle.textContent = 'New message to ' + recipient
  modalBodyInput.value = recipient
})

Change animation

The $modal-fade-transform variable determines the transform state of .modal-dialog before the modal fade-in animation, the $modal-show-transform variable determines the transform of .modal-dialog at the end of the modal fade-in animation.

If you want for example a zoom-in animation, you can set $modal-fade-transform: scale(.8).

Remove animation

For modals that simply appear rather than fade in to view, remove the .fade class from your modal markup.

<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true">
  ...
</div>

Dynamic heights

If the height of a modal changes while it is open, you should call myModal.handleUpdate() to readjust the modal’s position in case a scrollbar appears.

Accessibility

Be sure to add aria-labelledby="...", referencing the modal title, to .modal. Additionally, you may give a description of your modal dialog with aria-describedby on .modal. Note that you don’t need to add role="dialog" since we already add it via JavaScript.

Embedding YouTube videos

Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more information.

Optional sizes

Modals have three optional sizes, available via modifier classes to be placed on a .modal-dialog. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports.

Size	Class	Modal max-width
Small	`.modal-sm`	`300px`
Default	None	`500px`
Large	`.modal-lg`	`800px`
Extra large	`.modal-xl`	`1140px`

Our default modal without modifier class constitutes the “medium” size modal.

<div class="modal-dialog modal-xl">...</div>
<div class="modal-dialog modal-lg">...</div>
<div class="modal-dialog modal-sm">...</div>

Another override is the option to pop up a modal that covers the user viewport, available via modifier classes that are placed on a .modal-dialog.

Class	Availability
`.modal-fullscreen`	Always
`.modal-fullscreen-sm-down`	Below `576px`
`.modal-fullscreen-md-down`	Below `768px`
`.modal-fullscreen-lg-down`	Below `992px`
`.modal-fullscreen-xl-down`	Below `1200px`
`.modal-fullscreen-xxl-down`	Below `1400px`

<!-- Full screen modal -->
<div class="modal-dialog modal-fullscreen-sm-down">
  ...
</div>

What follows is just some placeholder text for this modal dialog. I feel like I'm already there. I’m gon’ put her in a coma. Boom, boom, boom. You're reading me like erotica, boy, you make me feel exotic, yeah. Happy birthday. From Tokyo to Mexico, to Rio. I knew you were.

Last Friday night. Calling out my name. Kiss her, touch her, squeeze her buns. Heavy is the head that wears the crown. So open up your heart and just let it begin. Boy all this time was worth the waiting. You know that I'm the girl that you should call. End of the rainbow looking treasure. You're reading me like erotica, boy, you make me feel exotic, yeah. Do you know that there's still a chance for you 'Cause there's a spark in you? So I sat quietly, agreed politely. From Tokyo to Mexico, to Rio.

Don't be a shy kinda guy I'll bet it's beautiful. You fall asleep during foreplay, 'Cause the pills you take, are more your forte. Open up your heart. You're never gonna be unsatisfied.

I should've told you what you meant to me 'Cause now I pay the price. Takes you miles high, so high, 'cause she’s got that one international smile.

Yo, shout out to all you kids, buying bottle service, with your rent money. So I sat quietly, agreed politely. They say, be afraid you're not like the others, futuristic lover. Boom, boom, boom. Don't need apologies. We can dance, until we die, you and I, will be young forever. If you choose to walk away, don’t walk away. You know that I'm the girl that you should call. This Friday night, do it all again.

I'm walking on air. But lil' mama so dope. It's time to bring out the big balloons. Are you ready for, ready for. The boys break their necks try'na to creep a little sneak peek. Summer after high school when we first met. If you want it all. (This is how we do) You open my eyes and I'm ready to go, lead me into the light.

Growing fast into a bolt of lightning. We freak in my jeep, Snoop Doggy Dogg on the stereo. Baby do you dare to do this? Open up your heart and just let it begin. Peach-pink lips, yeah, everybody stares. Be your teenage dream tonight. Are you brave enough to let me see your peacock? You think I'm funny when I tell the punchline wrong. Woo! I knew you were. All this money can't buy me a time machine. I can't sleep let's run away and don't ever look back, don't ever look back.

Make it like your birthday everyday. I'm not sticking around to watch you go down. Uh-huh, I see you. For you I'll risk it all, all. I’m gon’ put her in a coma. She ride me like a roller coaster. You hear my voice, you hear that sound. 'Cause I will love you unconditionally (oh yeah). They say, be afraid you're not like the others, futuristic lover. There is no fear now, let go and just be free, I will love you unconditionally.

We can dance, until we die, you and I, will be young forever. Pop your Pérignon. Last Friday night, yeah I think we broke the law, always say we're gonna stop. Don't need apologies. Give you something good to celebrate. But don’t make me your enemy, your enemy, your enemy. Flowers in her hair, she don't care. Tone, tan fit and ready, turn it up cause its gettin' heavy.

Loop

Responsive fullscreen modals are generated via the $breakpoints map and a loop in scss/_modal.scss.

@each $breakpoint in map-keys($grid-breakpoints) {
  $infix: breakpoint-infix($breakpoint, $grid-breakpoints);
  $postfix: if($infix != "", $infix + "-down", "");

  @include media-breakpoint-down($breakpoint) {
    .modal-fullscreen#{$postfix} {
      width: 100vw;
      max-width: none;
      height: 100%;
      margin: 0;

      .modal-content {
        height: 100%;
        border: 0;
        @include border-radius(0);
      }

      .modal-header {
        @include border-radius(0);
      }

      .modal-body {
        overflow-y: auto;
      }

      .modal-footer {
        @include border-radius(0);
      }
    }
  }
}

Usage

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the <body> to override default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.

Via data attributes

Activate a modal without writing JavaScript. Set data-bs-toggle="modal" on a controller element, like a button, along with a data-bs-target="#foo" or href="#foo" to target a specific modal to toggle.

<button type="button" data-bs-toggle="modal" data-bs-target="#myModal">Launch modal</button>

Via JavaScript

Create a modal with a single line of JavaScript:

var myModal = new bootstrap.Modal(document.getElementById('myModal'), options)

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-bs-, as in data-bs-backdrop="".

Name	Type	Default	Description
`backdrop`	boolean or the string `'static'`	`true`	Includes a modal-backdrop element. Alternatively, specify `static` for a backdrop which doesn't close the modal on click.
`keyboard`	boolean	`true`	Closes the modal when escape key is pressed
`focus`	boolean	`true`	Puts the focus on the modal when initialized.

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

Passing options

Activates your content as a modal. Accepts an optional options object.

var myModal = new bootstrap.Modal(document.getElementById('myModal'), {
  keyboard: false
})

toggle

Manually toggles a modal. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal or hidden.bs.modal event occurs).

myModal.toggle()

show

Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).

myModal.show()

hide

Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs).

myModal.hide()

handleUpdate

Manually readjust the modal’s position if the height of a modal changes while it is open (i.e. in case a scrollbar appears).

myModal.handleUpdate()

dispose

Destroys an element’s modal. (Removes stored data on the DOM element)

myModal.dispose()

getInstance

Static method which allows you to get the modal instance associated with a DOM element

var myModalEl = document.getElementById('myModal')
var modal = bootstrap.Modal.getInstance(myModalEl) // Returns a Bootstrap modal instance

Events

Bootstrap’s modal class exposes a few events for hooking into modal functionality. All modal events are fired at the modal itself (i.e. at the <div class="modal">).

Event type	Description
`show.bs.modal`	This event fires immediately when the `show` instance method is called. If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
`shown.bs.modal`	This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
`hide.bs.modal`	This event is fired immediately when the `hide` instance method has been called.
`hidden.bs.modal`	This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
`hidePrevented.bs.modal`	This event is fired when the modal is shown, its backdrop is `static` and a click outside the modal or an escape key press is performed with the keyboard option or `data-bs-keyboard` set to `false`.

var myModalEl = document.getElementById('myModal')
myModalEl.addEventListener('hidden.bs.modal', function (event) {
  // do something...
})
