Reorganize docs for easier deploys
With the current docs directory setup, I'm making too many mistakes and have to manually address path changes and directory moves on deploy. This makes for a frustrating experience developing locally and shipping releases. With this PR, we're basically back to the same setup from v3—duplicating the dist directory into our docs directory. Not the most ideal, but very straightforward for me as the release manager.

Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the `height` from it's current value to `0`. Given how CSS handles animations, you cannot use `padding` on a `.collapse` element. Instead, use the class as an independent wrapping element. - -## Example - -Click the buttons below to show and hide another element via class changes: - -- `.collapse` hides content -- `.collapsing` is applied during transitions -- `.collapse.show` shows content - -You can use a link with the `href` attribute, or a button with the `data-target` attribute. In both cases, the `data-toggle="collapse"` is required. - -{% capture example %} -<p> - <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample"> - Link with href - </a> - <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample"> - Button with data-target - </button> -</p> -<div class="collapse" id="collapseExample"> - <div class="card card-body"> - Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid.

This attribute explicitly conveys the current state of the collapsible element tied to the control to screen readers and similar assistive technologies. If the collapsible element is closed by default, the attribute on the control element should have a value of `aria-expanded="false"`. If you've set the collapsible element to be open by default using the `show` class, set `aria-expanded="true"` on the control instead. The plugin will automatically toggle this attribute on the control based on whether or not the collapsible element has been opened or closed (via JavaScript, or because the user triggered another control element also tied to the same collapsbile element). If the control element's HTML element is not a button (e.g., an `<a>` or `<div>`), the attribute `role="button"` should be added to the element. - -If your control element is targeting a single collapsible element – i.e. the `data-target` attribute is pointing to an `id` selector – you should add the `aria-controls` attribute to the control element, containing the `id` of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself. - -Note that Bootstrap's current implementation does not cover the various keyboard interactions described in the [WAI-ARIA Authoring Practices 1.1 accordion pattern](https://www.w3.org/TR/wai-aria-practices-1.1/#accordion) - you will need to include these yourself with custom JavaScript. - -## Usage - -The collapse plugin utilizes a few classes to handle the heavy lifting: - -- `.collapse` hides the content -- `.collapse.show` shows the content -- `.collapsing` is added when the transition starts, and removed when it finishes - -These classes can be found in `_transitions.scss`. - -### Via data attributes - -Just add `data-toggle="collapse"` and a `data-target` to the element to automatically assign control of one or more collapsible elements. The `data-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element. If you'd like it to default open, add the additional class `show`. - -To add accordion-like group management to a collapsible area, add the data attribute `data-parent="#selector"`. Refer to the demo to see this in action. - -### Via JavaScript - -Enable manually with: - -{% highlight js %} -$('.collapse').collapse() -{% endhighlight %} - -### Options - -Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-parent=""`. - -<table class="table table-bordered table-striped"> - <thead> - <tr> - <th style="width: 100px;">Name</th> - <th style="width: 50px;">Type</th> - <th style="width: 50px;">Default</th> - <th>Description</th> - </tr> - </thead> - <tbody> - <tr> - <td>parent</td> - <td>selector | jQuery object | DOM element </td> - <td>false</td> - <td>If parent is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown.
