<object> elements must have alternative text.

Severity: Serious

Description

The <object> HTML element serves various purposes such as displaying images, embedding browsing contexts, or handling plugins. To ensure accessibility, it is important to provide a text alternative for the <object> element so that screen reader users can understand its content. This text alternative, known as an accessible name, should accurately describe the contents of the <object>. However, if the <object> element is purely presentational and doesn’t require accessibility, you can use role="none" or role="presentation" to remove it from the accessibility tree.

Why is it important?

Screen readers rely on alternative text to convey the meaning of non-text content to users, as they are unable to directly interpret such content. When it comes to embedded object elements, it is crucial to provide short and descriptive alternative text. This ensures that screen reader users can obtain the information contained within these elements. The alternative text should accurately convey the intent, purpose, and meaning of the image, allowing assistive technologies to effectively communicate it to users.

Examples

  • Success:

    • <object> element has a non-empty aria-label attribute.
  • Failure:

    • <object> element has no alternative text.

How to fix?

Each <object> element can provide alternative text using one of the methods -

  1. An aria-labelledby attribute that references elements that are visible to screen readers.
  2. A non-empty title attribute
  3. A non-empty aria-label attribute
