 Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
 
 - Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
-- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/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.

 ## Example
 
 Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit.

 Dropdowns are built on a third party library, [Popper.js](https://popper.js.org/), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js]({{< param "cdn.popper" >}}) before Bootstrap's JavaScript or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js. Popper.js isn't used to position dropdowns in navbars though as dynamic positioning isn't required.

 ## Accessibility
 
 The [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr>](https://www.w3.org/TR/wai-aria/) standard defines an actual [`role="menu"` widget](https://www.w3.org/WAI/PF/aria/roles#menu), but this is specific to application-like menus which trigger actions or functions. <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus can only contain menu items, checkbox menu items, radio button menu items, radio button groups, and sub-menus.

 Dynamic tabbed interfaces, as described in the [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr> Authoring Practices](https://www.w3.org/TR/wai-aria-practices/#tabpanel), require `role="tablist"`, `role="tab"`, `role="tabpanel"`, and additional `aria-` attributes in order to convey their structure, functionality and current state to users of assistive technologies (such as screen readers).
 
 Note that dynamic tabbed interfaces should <em>not</em> contain dropdown menus, as this causes both usability and accessibility issues. From a usability perspective, the fact that the currently displayed tab's trigger element is not immediately visible (as it's inside the closed dropdown menu) can cause confusion. From an accessibility point of view, there is currently no sensible way to map this sort of construct to a standard WAI ARIA pattern, meaning that it cannot be easily made understandable to users of assistive technologies.

 Scrollspy has a few requirements to function properly:
 
-- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
 - It must be used on a Bootstrap [nav component]({{< docsref "/components/navs" >}}) or [list group]({{< docsref "/components/list-group" >}}).
 - Scrollspy requires `position: relative;` on the element you're spying on, usually the `<body>`.
 - When spying on elements other than the `<body>`, be sure to have a `height` set and `overflow-y: scroll;` applied.
