How to Fix the Problem

  • The aria-braillelabel or aria-brailleroledescription attribute may have been placed on the wrong element, such as a parent or child of the correct element. The attribute should be put on a different element.
  • The element with aria-braillelabel attribute needs an aria-label attribute or other attribute that gives it an accessible name.
  • The element with aria-brailleroledescription attribute needs a aria-roledescription attribute.
  • The aria-braillelabel or aria-brailleroledescription attribute serves no function and should be removed.

Good aria-braillelabel:

<button aria-braillelabel="****">
  <img alt="4 stars" src="images/stars.jpg">
</button>

Bad aria-braillelabel:

<img alt="" aria-braillelabel="****" src="images/stars.jpg">

Good aria-brailleroledescription

<div
  role="article" id="slide" aria-labelledby="slideheading"
  aria-roledescription="slide"
  aria-brailleroledescription="sld"
>
  <h1 id="slideheading">My vacation in Rome</h1>
</div>

Bad aria-brailleroledescription

<div
  role="article" id="slide" aria-labelledby="slideheading"
  aria-brailleroledescription="slide"
>
  <h1 id="slideheading">My vacation in Rome</h1>
</div>

Why it Matters

ARIA braille attributes were introduced to allow adjusting how labels and role descriptions are rendered on a braille display. They cannot be the only attribute providing a label, or a role description. When used without a corresponding label or role description ARIA says to ignore these attributes, although this may not happen consistently in screen readers and other assistive technologies.

Rule Description

WAI-ARIA requires that the aria-braillelabel attribute is only ever used on elements with an accessible name, such as from aria-label. Similarly, aria-brailleroledescription is required to only ever be used on elements with aria-roledescription.

The Algorithm (in simple terms)

Checks that aria-braillelabel is only used on elements with a non-empty label, and that aria-brailleroledescription is only used on elements with a non-empty aria-roledescription.
