Summary - Accessible tabpanel

HTML course · Expert · Lesson 12/39

Write a tabpanel component skeleton with all ARIA patterns.

What we learned in this group

In this group you met the ARIA patterns:

  • The role attribute and its four classes: widget, document, landmark, abstract.
  • State vs property: aria-expanded, aria-hidden, aria-disabled.
  • Grid and tree patterns: role="grid", role="tree", role="treegrid".
  • Tabs and accordion: tablist, tab, tabpanel, aria-selected.
  • Menu and menubar: aria-haspopup, menuitem.

Now we will combine them into one accessible tabpanel skeleton.

Exercise Accessible tabpanel skeleton

Add a <div role="tablist"> to body; inside it put two <button role="tab">. The first tab has id t1, aria-selected true, aria-controls p1 and the text General. The second tab has aria-selected false, aria-controls p2 and the text Details. Add a <div role="tabpanel" id="p1" aria-labelledby="t1"> to body with a <p> inside, its text General content.

Show example solution 
<body>
  <div role="tablist">
    <button role="tab" id="t1" aria-selected="true" aria-controls="p1">General</button>
    <button role="tab" aria-selected="false" aria-controls="p2">Details</button>
  </div>
  <div role="tabpanel" id="p1" aria-labelledby="t1">
    <p>General content.</p>
  </div>
</body>

Test yourself

  1. Match each role to its meaning

    role="tablist"
    Tab list
    role="tab"
    Single tab
    role="tabpanel"
    Tab content
    aria-selected="true"
    Selected tab
    aria-controls="p1"
    Tab to panel link

  2. Which attribute tells that a tab controls its content region?

    • aria-labelledby
    • aria-controls
    • aria-expanded
    • aria-haspopup
    Show answer

    aria-controls — Correct. aria-controls carries the id of the element an item controls.

  3. Complete the selected tab's attribute

    <button role="tab" aria-selected="____" aria-controls="p1">General</button>
    Show answer 
    <button role="tab" aria-selected="true" aria-controls="p1">General</button>
