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

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>
</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">

wb-ready.wb-tabs (v4.0.5+) Triggered automatically after a tabbed interface or carousel initializes. Used to identify which tabbed interface or carousel was initialized (target of the event)
