How to Fix The Problem

<embed> elements must contain <noembed> elements. This will provide a description of the content of the <embed> element in case it does not load.

The Algorithm, In Simple Terms

The engine scans the page for <embed> elements with missing child or sibling <noembed> elements.

Why Is It Important?

Users who use assistive tools, such as screen readers, rely on the <noembed> element to provide a description of the content of the <embed> element.

Code Example

<embed type="video/webm" src="video.mp4">
    <h1>Alternative Content</h1>
