## Purpose

Dynamically stacks multiple sections of content, transforming them into a tabbed interface. Implements the WAI-ARIA tab panel design pattern for large screens and the WAI-ARIA accordion design pattern for small screens.

## Working example

- English example
- French example

## How to implement

### Tabbed interface

1. Add a `div` element to the page with the class `wb-tabs`.
2. Add a `div` element to the previous `div` element with the class `tabpanels`.
3. For each tab panel, add a `details` element with a unique `id`. Add `open="open"` for the tab panel that should be open by default.

       <div class="wb-tabs">
       	<div class="tabpanels">
       		<details id="details-panel1">
       			...
       		</details>
       		<details id="details-panel2" open="open">
       			...
       		</details>

4. Add a `summary` element with the label of the tab to each `details` element.

       <details id="details-panel1">
       		<summary>Example 1</summary>
       		...
       	</details>
       	<details id="details-panel2" open="open">
       		<summary>Example 2</summary>
       		...
       	</details>

5. Add the tab panel content after each `summary` element.

#### Code

    <div class="wb-tabs">
    	<div class="tabpanels">
    		<details id="details-panel1">
    			<summary>Example 1</summary>
    			<p>
    				...
    			</p>
    		</details>
    		<details id="details-panel2" open="open">
    			<summary>Example 2</summary>
    			<p>
    				...
    			</p>
    		</details>
    		...
    	</div>
    </div>

### Carousel

1. Add a `div` element to the page with the class `wb-tabs` and either the styling class `carousel-s1` or `carousel-s2`.
2. Add a `div` element to the previous `div` element with the class `tabpanels`.
3. For each tab panel, add a `div` element with a unique id, `role="tabpanel"` and `class="out"`. For the tab panel that should be opened by default, replace the `out` class with `in`.
4. Specify the tab panel transition type by adding one of the following classes to the `div` element for each of the tab panels:
   - `fade`: Fading transition
   - `slide`: Horizontal sliding transition
   - `slidevert`: Vertical sliding transition

       <div class="wb-tabs carousel-s1">
       	<div class="tabpanels">
       		<div role="tabpanel" id="panel1" class="in fade">
       		</div>
       		<div role="tabpanel" id="panel2" class="out fade">
       		</div>
       	</div>
       </div>

5. Add a `figure` element to each tab panel.
6. Add content to each `figure` element:
   - Image: Add an image to the `figure` element followed by a `figcaption` element with the caption for the tab panel.

         <div role="tabpanel" id="panel1" class="in fade">
         	<figure>
         		<img src="img/protect-environment.jpg" alt="Panel 1" />
         		<figcaption>
         			<p>

         			</p>
         		</figcaption>
         	</figure>
         </div>

   - Video: Add a multimedia player to the `figure` element according to the multimedia player documentation.

         <div role="tabpanel" id="panel1" class="in fade">
         	<figure class="wb-mltmd">
         		<video poster="../multimedia/demo/video1-en.jpg" title="Looking for a Job">
         			<source type="video/webm" src="http://video2.servicecanada.gc.ca/video/boew-wet/te-lj-eng.webm" />
         			<source type="video/mp4" src="http://video2.servicecanada.gc.ca/video/boew-wet/te-lj-eng.mp4" />
         			<track src="../multimedia/cpts-lg-en.html" kind="captions" data-type="text/html" srclang="en" label="English" />
         		</video>
         		<figcaption>
         			<p>Looking for a Job (<a href="../multimedia/cpts-lg-en.html">Transcript</a>)</p>
         		</figcaption>
         	</figure>
         </div>

   - Other content: Add content to the `figure` element followed by a `figcaption` element with the caption for the tab panel.

         <div role="tabpanel" id="panel1" class="in fade">
         	<figure>
         		<table>
         			...
         		</table>
         		<figcaption>
         			<p>Tab panel caption</p>
         		</figcaption>
         	</figure>
         </div>

7. Add a `ul` element with `role="tablist"` at the start of the `div` element with the `wb-tabs` class.
8. For each tab panel, add an `li` element to the previous `ul` element. Add `class="active"` for the tab panel that should be open by default.
9. Add an `a` element to each `li` element
10. Add to each `li` element an `a` element with the label of the tab and that links to the associated tab panel.

        <ul role="tablist">
        	<li class="active"><a href="#panel27">Tab 1</a></li>
        	<li><a href="#panel28">Tab 2</a></li>
        		...
        </ul>

11. Optional: Override the default settings using the configuration options.
12. Optional: Add an external link that affects which tab is visible. The href attribute includes the id of the panel to make visible. (v4.0.8+)

        <p><a href="#panel3" class="wb-tabs-ext">Show the third panel</a></p>

    <div class="wb-tabs carousel-s1">
    	<ul role="tablist">
    		<li class="active"><a href="#panel1">Tab 1</a></li>
    		<li><a href="#panel2">Tab 2</a></li>
    		...
    	</ul>
    	<div class="tabpanels">
