Collapsible section has no label

Why does it matter?

WCAG 4.1.2 asks that every control has a name; the summary of a collapsible section opens and closes it, and with no text screen readers announce only "disclosure triangle", with nothing to say what is inside.

Who it affects: Screen reader users, voice-control users who say a field's label to move to it, and people with memory or attention difficulties who lose a placeholder once they type.

What does Lumtera flag?

A <summary> with no text, the line of a Details block that opens and closes it.

Check ID summary-no-name — use it to filter the content report or with wp lumtera issues --rule.

How do I fix it in WordPress?

Type a short label into the summary line of the Details block, such as "Opening times".

Example

<details><summary></summary>Monday to Friday, 9 to 5</details>

<details><summary>Opening times</summary>Monday to Friday, 9 to 5</details>

How do I check the fix?

1. Update the post. The issue disappears from the Lumtera Accessibility sidebar on the next check, and from the site report on the next scan.
2. Click each field's label: the cursor should move into the field. With a screen reader, each field should announce its label when it receives focus.
