Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
|
||||
Modals are streamlined, but flexible dialog prompts powered by JavaScript. They support a number of use cases from user notification to completely custom content and feature a handful of helpful subcomponents, sizes, and more.

**Due to how HTML5 defines its semantics, [the `autofocus` HTML attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attr-autofocus) has no effect in Bootstrap modals.** To achieve the same effect, use some custom JavaScript:
|
||||
## 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.
|
||||
- Modal's use `position: fixed`, which can sometimes be a bit particular about it's 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.
|
||||
- One again, due to `position: fixed`, there are some caveats with using modals on mobile devices. [See our browser support docs]({{ site.baseurl }}/getting-started/browsers-devices/#modals-and-dropdowns-on-mobile) for details.
|
||||
- Lastly, the `autofocus` HTML attribute has no affect in modals. Here's how you can achieve the same effect with custom JavaScript.
|
||||
|
||||
Keep reading for demos and usage guidelines.

#### Multiple open modals not supported
|
||||
## Examples
|
||||
|
||||
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.

#### Modal markup placement
|
||||
|
||||
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality. Placing it within a `position: fixed;` element may adversely affect placement.

### Static example

A rendered modal with header, body, and set of actions in the footer.
|

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.

#### Make modals accessible

### Scrolling long content
|
||||
|
||||
Be sure to add `role="dialog"` and `aria-labelledby="..."`, referencing the modal title, to `.modal`, and `role="document"` to the `.modal-dialog` itself.
|
||||
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.
|
||||
|
||||
Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`.

### 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.

### Varying modal content
|
||||
|
||||
Have a bunch of buttons that all trigger the same modal with slightly different contents? Use `event.relatedTarget` and [HTML `data-*` attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) (possibly [via jQuery](https://api.jquery.com/data/)) 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](#events) for details on `relatedTarget`.
|
||||
|
||||
{% example html %}
|
||||
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
|
||||
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@fat">Open modal for @fat</button>
|
||||
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
|
||||

||||

{% highlight js %}
|
||||
$('#exampleModal').on('show.bs.modal', function (event) {
|
||||
var button = $(event.relatedTarget) // Button that triggered the modal
|
||||
var recipient = button.data('whatever') // Extract info from data-* attributes
|
||||
// If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
|
||||
// Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
|
||||
var modal = $(this)
|
||||
modal.find('.modal-title').text('New message to ' + recipient)
|
||||
modal.find('.modal-body input').val(recipient)
|
||||
})
|
||||
{% endhighlight %}
|
||||
|
||||
### Remove animation
|
||||
|
||||
For modals that simply appear rather than fade in to view, remove the `.fade` class from your modal markup.
|
||||
|
||||
{% highlight html %}
|
||||
<div class="modal" tabindex="-1" role="dialog" aria-labelledby="..." aria-hidden="true">
|
||||
...
|
||||
</div>
|
||||
{% endhighlight %}
|
||||
|
||||
### Dynamic heights
|
||||
|
||||
If the height of a modal changes while it is open, you should call `$('#myModal').data('bs.modal').handleUpdate()` to readjust the modal's position in case a scrollbar appears.
|
||||
|
||||
### Accessibility
|
||||
|
||||
Be sure to add `role="dialog"` and `aria-labelledby="..."`, referencing the modal title, to `.modal`, and `role="document"` to the `.modal-dialog` itself. Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`.
|
||||
|
||||
### 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](https://stackoverflow.com/questions/18622508/bootstrap-3-and-youtube-in-modal) for more information.

## Using the grid system
|

|

To take advantage of the Bootstrap grid system within a modal, just nest `.container-fluid` within the `.modal-body` and then use the normal grid system classes within this container.

## Modals with dynamic heights
|
||||
|
||||
If the height of a modal changes while it is open, you should call `$('#myModal').data('bs.modal').handleUpdate()` to readjust the modal's position in case a scrollbar appears.
|
||||
|
||||
## 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.
