 Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/engineering/en_us/a/2010/hack-week.html) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.

With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.

 With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS's flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.

+- If you're building our JavaScript from source, it [requires `util.js`](/docs/{{< param docs_version >}}/getting-started/javascript/#util). The compiled version includes this.
 - Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
 - On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
 - To animate alerts when dismissing them, be sure to add the `.fade` and `.show` classes.

 Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.
 
 Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.

 ##### Ensure correct `role` and provide a label
 
 In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate `role` attribute needs to be provided. For button groups, this would be `role="group"`, while toolbars should have a `role="toolbar"`.
 
 In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use `aria-label`, but alternatives such as `aria-labelledby` can also be used.

 The `.disabled` class uses `pointer-events: none` to try to disable the link functionality of `<a>`s, but that CSS property is not yet standardized. In addition, even in browsers that do support `pointer-events: none`, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links.

 ## Horizontal
 
 Using a combination of grid and utility classes, cards can be made horizontal in a mobile-friendly and responsive way. In the example below, we remove the grid gutters with `.no-gutters` and use `.col-md-*` classes to make the card horizontal at the `md` breakpoint. Further adjustments may be needed depending on your card content.

 Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is [an intentional design decision](http://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/).

 ## Usage
 
 Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the `.show` class on the parent list item. The `data-toggle="dropdown"` attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.
 
-{% capture callout %}
+{{< callout info >}}
 On touch-enabled devices, opening a dropdown adds empty (`$.noop`) `mouseover` handlers to the immediate children of the `<body>` element. This admittedly ugly hack is necessary to work around a [quirk in iOS' event delegation](https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html), which would otherwise prevent a tap anywhere outside of the dropdown from triggering the code that closes the dropdown. Once the dropdown is closed, these additional empty `mouseover` handlers are removed.

 ### Inline forms
 
 Use the `.form-inline` class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms vary slightly from their default states.
 
-- Controls are `display: flex`, collapsing any HTML white space and allowing you to provide alignment control with [spacing]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) and [flexbox]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) utilities.
+- Controls are `display: flex`, collapsing any HTML white space and allowing you to provide alignment control with [spacing](/docs/{{< param docs_version >}}/utilities/spacing/) and [flexbox](/docs/{{< param docs_version >}}/utilities/flex/) utilities.
 - Controls and input groups receive `width: auto` to override the Bootstrap default `width: 100%`.
 - Controls **only appear inline in viewports that are at least 576px wide** to account for narrow viewports on mobile devices.
 
-You may need to manually address the width and alignment of individual form controls with [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) (as shown below). Lastly, be sure to always include a `<label>` with each form control, even if you need to hide it from non-screenreader visitors with `.sr-only`.

 ##### Alternatives to hidden labels
+
 Assistive technologies such as screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the `.sr-only` class. There are further alternative methods of providing a label for assistive technologies, such as the `aria-label`, `aria-labelledby` or `title` attribute. If none of these are present, assistive technologies may resort to using the `placeholder` attribute, if present, but note that use of `placeholder` as a replacement for other labelling methods is not advised.
-{% endcapture %}
-{% include callout.html content=callout type="warning" %}

 ## Help text
 
 Block-level help text in forms can be created using `.form-text` (previously known as `.help-block` in v3). Inline help text can be flexibly implemented using any inline HTML element and utility classes like `.text-muted`.
 
-{% capture callout %}
+{{< callout warning >}}
 ##### Associating help text with form controls
 
 Help text should be explicitly associated with the form control it relates to using the `aria-describedby` attribute. This will ensure that assistive technologies—such as screen readers—will announce this help text when the user focuses or enters the control.
-{% endcapture %}
-{% include callout.html content=callout type="warning" %}
+{{< /callout >}}
 
 Help text below inputs can be styled with `.form-text`. This class includes `display: block` and adds some top margin for easy spacing from the inputs above.
 
-{% capture example %}
+{{< example >}}

 ##### Caveat with anchors
 
 By default, browsers will treat all native form controls (`<input>`, `<select>` and `<button>` elements) inside a `<fieldset disabled>` as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes `<a ... class="btn btn-*">` elements, these will only be given a style of `pointer-events: none`.

 ## Validation

 ### Range
 
 Create custom `<input type="range">` controls with `.custom-range`. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only Firefox supports "filling" their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.
 
-{% capture example %}
+{{< example >}}
 <label for="customRange1">Example range</label>
 <input type="range" class="custom-range" id="customRange1">
-{% endcapture %}
-{% include example.html content=example %}
+{{< /example >}}
 
 Range inputs have implicit values for `min` and `max`—`0` and `100`, respectively. You may specify new values for those using the `min` and `max` attributes.
 
-{% capture example %}
+{{< example >}}

-{% endcapture %}
-{% include example.html content=example %}
+{{< /example >}}
 
 By default, range inputs "snap" to integer values. To change this, you can specify a `step` value. In the example below, we double the number of steps by using `step="0.5"`.
 
-{% capture example %}
+{{< example >}}

 The [`:lang()` pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:lang) is used to allow for translation of the "Browse" text into other languages. Override or add entries to the `$custom-file-text` Sass variable with the relevant [language tag](https://en.wikipedia.org/wiki/IETF_language_tag) and localized strings. The English strings can be customized the same way. For example, here's how one might add a Spanish translation (Spanish's language code is `es`):
 
-{% highlight scss %}
+{{< highlight scss >}}
 $custom-file-text: (
   en: "Browse",
   es: "Elegir"
 );
-{% endhighlight %}
+{{< /highlight >}}
 
 Here's `lang(es)` in action on the custom file input for a Spanish translation:

 You'll need to set the language of your document (or subtree thereof) correctly in order for the correct text to be shown. This can be done using [the `lang` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang) on the `<html>` element or the [`Content-Language` HTTP header](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.12), among other methods.

 The [media object](http://www.stubbornella.org/content/2010/06/25/the-media-object-saves-hundreds-of-lines-of-code/) helps build complex and repetitive components where some media is positioned alongside content that doesn't wrap around said media. Plus, it does this with only two required classes thanks to flexbox.

 ## Media list
 
 Because the media object has so few structural requirements, you can also use these classes on list HTML elements. On your `<ul>` or `<ol>`, add the `.list-unstyled` to remove any browser default list styles, and then apply `.media` to your `<li>`s. As always, use spacing utilities wherever needed to fine tune.

 - 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]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/browsers-devices/#modals-and-dropdowns-on-mobile) for details.

 - 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:

 ## Containers
 
 Although it's not required, you can wrap a navbar in a `.container` to center it on a page or add one within to only center the contents of a [fixed or static top navbar](#placement).
 
-{% capture example %}

 </div>
-{% endcapture %}
-{% include example.html content=example %}
+{{< /example >}}
 
 When the container is within your navbar, its horizontal padding is removed at breakpoints lower than your specified `.navbar-expand{-sm|-md|-lg|-xl}` class. This ensures we're not doubling up on padding unnecessarily on lower viewports when your navbar is collapsed.
 
-{% capture example %}

 ## Placement
 
-Use our [position utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/position/) to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use `position: fixed`, meaning they're pulled from the normal flow of the DOM and may require custom CSS (e.g., `padding-top` on the `<body>`) to prevent overlap with other elements.

 To easily add scrollspy behavior to your topbar navigation, add `data-spy="scroll"` to the element you want to spy on (most typically this would be the `<body>`). Then add the `data-target` attribute with the ID or class of the parent element of any Bootstrap `.nav` component.

 ### Colors
 
 The border spinner uses `currentColor` for its `border-color`, meaning you can customize the color with [text color utilities][color]. You can use any of our text color utilities on the standard spinner.

-{% for color in site.data.theme-colors %}

-{% endcapture %}
-{% include callout.html content=callout type="info" %}

 ## Growing spinner
 
 If you don't fancy a border spinner, switch to the grow spinner. While it doesn't technically spin, it does repeatedly grow!

 ## Accessibility
 
-Toasts are intended to be small interruptions to your visitors or users, so to help those with screen readers and similar assistive technologies, you should wrap your toasts in an [`aria-live` region](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Live_Regions). Changes to live regions (such as injecting/updating a toast component) are automatically announced by screen readers without needing to move the user's focus or otherwise interrupt the user. Additionally, include `aria-atomic="true"` to ensure that the entire toast is always announced as a single (atomic) unit, rather than announcing what was changed (which could lead to problems if you only update part of the toast's content, or if displaying the same toast content at a later point in time). If the information needed is important for the process, e.g. for a list of errors in a form, then use the [alert component]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/alerts/) instead of toast.

 $('#example').tooltip(options)
-{% endhighlight %}

-{% capture callout %}
+{{< callout warning >}}
 ##### Overflow `auto` and `scroll`
 
 Tooltip position attempts to automatically change when a parent container has `overflow: auto` or `overflow: scroll` like our `.table-responsive`, but still keeps the original placement's positioning. To resolve, set the `boundary` option to anything other than default value, `'scrollParent'`, such as `'window'`:

+{{< /callout >}}
 
 ### Markup
 
 The required markup for a tooltip is only a `data` attribute and `title` on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to `top` by the plugin).
 
-{% capture callout %}

 ##### Making tooltips work for keyboard and assistive technology users
 
 You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation.
 
 Additionally, do not rely solely on `hover` as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users.

 ### Disabled elements
 
 Elements with the `disabled` attribute aren't interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you'll want to trigger the tooltip from a wrapper `<div>` or `<span>`, ideally made keyboard-focusable using `tabindex="0"`, and override the `pointer-events` on the disabled element.

 HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](https://purecss.io/), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.

 - For a more inclusive and accessible type scale, we assume the browser default root `font-size` (typically 16px) so visitors can customize their browser defaults as needed.
 - Use the `$font-family-base`, `$font-size-base`, and `$line-height-base` attributes as our typographic base applied to the `<body>`.
 - Set the global link color via `$link-color` and apply link underlines only on `:hover`.

 ## Summary
 
@@ -54,13 +55,13 @@ Bootstrap includes several components that function as an overlay of some kind.
 
 Each overlay component increases it's `z-index` value slightly in such a way that common UI principles allow user focused or hovered elements to remain in view at all times. For example, a modal is document blocking (e.g., you cannot take any other action save for the modal's action), so we put that above our navbars.

 ## HTML and CSS over JS
 
 Whenever possible, we prefer to write HTML and CSS over JavaScript. In general, HTML and CSS are more prolific and accessible to more people of all different experience levels. HTML and CSS are also faster in your browser than JavaScript, and your browser generally provides a great deal of functionality for you.
 
-This principle is our first-class JavaScript API is `data` attributes. You don't need to write nearly any JavaScript to use our JavaScript plugins; instead, write HTML. Read more about this in [our JavaScript overview page]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#data-attributes).

Read more about this in [our JavaScript overview page](/docs/{{< param docs_version >}}/getting-started/javascript/#data-attributes).
 
 Lastly, our styles build on the fundamental behaviors of common web elements. Whenever possible, we prefer to use what the browser provides. For example, you can put a `.btn` class on nearly any element, but most elements don't provide any semantic value or browser functionality. So instead, we use `<button>`s and `<a>`s.

 Content which should be visually hidden, but remain accessible to assistive technologies such as screen readers, can be styled using the `.sr-only` class. This can be useful in situations where additional visual information or cues (such as meaning denoted through the use of color) need to also be conveyed to non-visual users.

 For visually hidden interactive controls, such as traditional "skip" links, `.sr-only` can be combined with the `.sr-only-focusable` class. This will ensure that the control becomes visible once focused (for sighted keyboard users).

 ## Selectors
 
 Currently to query DOM elements we use the native methods `querySelector` and `querySelectorAll` for performance reasons, so you have to use [valid selectors](https://www.w3.org/TR/CSS21/syndata.html#value-def-identifier).
 If you use special selectors, for example: `collapse:Example` be sure to escape them.

 All infinitive events provide [`preventDefault()`](https://developer.mozilla.org/en-US/docs/Web/API/Event/preventDefault) functionality. This provides the ability to stop the execution of an action before it starts. Returning false from an event handler will also automatically call `preventDefault()`.
 
-{% highlight js %}
+{{< highlight js >}}
 $('#myModal').on('show.bs.modal', function (e) {
   if (!data) {
     return e.preventDefault() // stops modal from being shown
   }
 })
-{% endhighlight %}
+{{< /highlight >}}
 
 ## Programmatic API
 
 We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
 
-{% highlight js %}
+{{< highlight js >}}
 $('.btn.danger').button('toggle').addClass('fat')
-{% endhighlight %}
+{{< /highlight >}}
 
 All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
 
-{% highlight js %}
+{{< highlight js >}}
 $('#myModal').modal() // initialized with defaults
 $('#myModal').modal({ keyboard: false }) // initialized with no keyboard
 $('#myModal').modal('show') // initializes and invokes show immediately
-{% endhighlight %}
+{{< /highlight >}}
 
 Each plugin also exposes its raw constructor on a `Constructor` property: `$.fn.popover.Constructor`. If you'd like to get a particular plugin instance, retrieve it directly from an element: `$('[rel="popover"]').data('popover')`.

 In order to execute an action once the transition is complete, you can listen to the corresponding event.

 ### Default settings
 
 You can change the default settings for a plugin by modifying the plugin's `Constructor.Default` object:
 
-{% highlight js %}
+{{< highlight js >}}
 // changes default for the modal plugin's `keyboard` option to false
 $.fn.modal.Constructor.Default.keyboard = false
-{% endhighlight %}
+{{< /highlight >}}
 
 ## No conflict
 
 Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call `.noConflict` on the plugin you wish to revert the value of.
 
-{% highlight js %}
+{{< highlight js >}}
 var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
 $.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
-{% endhighlight %}
+{{< /highlight >}}
 
 ## Version numbers
 
 The version of each of Bootstrap's plugins can be accessed via the `VERSION` property of the plugin's constructor. For example, for the tooltip plugin:
 
-{% highlight js %}
-$.fn.tooltip.Constructor.VERSION // => "{{ site.current_version }}"
-{% endhighlight %}
+{{< highlight js >}}
+$.fn.tooltip.Constructor.VERSION // => "{{< param current_version >}}"
+{{< /highlight >}}
 
 ## No special fallbacks when JavaScript is disabled
 
 Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use [`<noscript>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript) to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.
 
-{% capture callout %}
+{{< callout warning >}}
 ##### Third-party libraries
 
 **Bootstrap does not officially support third-party JavaScript libraries** like Prototype or jQuery UI. Despite `.noConflict` and namespaced events, there may be compatibility problems that you need to fix on your own.

 Moving beyond the columns themselves, you may also customize the number of grid tiers. If you wanted just four grid tiers, you'd update the `$grid-breakpoints` and `$container-max-widths` to something like this:

 When making any changes to the Sass variables or maps, you'll need to save your changes and recompile. Doing so will output a brand new set of predefined grid classes for column widths, offsets, and ordering. Responsive visibility utilities will also be updated to use the custom breakpoints. Make sure to set grid values in `px` (not `rem`, `em`, or `%`).

+title: Utilities for layout
+description: For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
+group: layout
+toc: true
+---
+
+## Changing `display`
+
+Use our [display utilities](/docs/{{< param docs_version >}}/utilities/display/) for responsively toggling common values of the `display` property. Mix it with our grid system, content, or components to show or hide them across specific viewports.
+
+## Flexbox options
+
+Bootstrap 4 is built with flexbox, but not every element's `display` has been changed to `display: flex` as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of [our components](/docs/{{< param docs_version >}}/components/alerts/) are built with flexbox enabled.
+
+Should you need to add `display: flex` to an element, do so with `.d-flex` or one of the responsive variants (e.g., `.d-sm-flex`). You'll need this class or `display` value to allow the use of our extra [flexbox utilities](/docs/{{< param docs_version >}}/utilities/flex/) for sizing, alignment, spacing, and more.
+
+## Margin and padding
+
+Use the `margin` and `padding` [spacing utilities](/docs/{{< param docs_version >}}/utilities/spacing/) to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities, based on a `1rem` value default `$spacer` variable. Choose values for all viewports (e.g., `.mr-3` for `margin-right: 1rem`), or pick responsive variants to target specific viewports (e.g., `.mr-md-3` for `margin-right: 1rem` starting at the `md` breakpoint).
+
+## Toggle `visibility`
+
+When toggling `display` isn't needed, you can toggle the `visibility` of an element with our [visibility utilities](/docs/{{< param docs_version >}}/utilities/visibility/). Invisible elements will still affect the layout of the page, but are visually hidden from visitors.

   - If you were using Affix to apply additional, non-`position` styles, the polyfills might not support your use case. One option for such uses is the third-party [ScrollPos-Styler](https://github.com/acch/scrollpos-styler) library.

 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.

-title: Utilities for layout
-description: For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
-group: layout
-toc: true
----
-
-## Changing `display`
-
-Use our [display utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/) for responsively toggling common values of the `display` property. Mix it with our grid system, content, or components to show or hide them across specific viewports.
-
-## Flexbox options
-
-Bootstrap 4 is built with flexbox, but not every element's `display` has been changed to `display: flex` as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of [our components]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/alerts/) are built with flexbox enabled.
-
-Should you need to add `display: flex` to an element, do so with `.d-flex` or one of the responsive variants (e.g., `.d-sm-flex`). You'll need this class or `display` value to allow the use of our extra [flexbox utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) for sizing, alignment, spacing, and more.
-
-## Margin and padding
-
-Use the `margin` and `padding` [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities, based on a `1rem` value default `$spacer` variable. Choose values for all viewports (e.g., `.mr-3` for `margin-right: 1rem`), or pick responsive variants to target specific viewports (e.g., `.mr-md-3` for `margin-right: 1rem` starting at the `md` breakpoint).
-
-## Toggle `visibility`
-
-When toggling `display` isn't needed, you can toggle the `visibility` of an element with our [visibility utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/visibility/). Invisible elements will still affect the layout of the page, but are visually hidden from visitors.
