How do you ensure accessibility when using images and multimedia in HTML?

Asked on Jan 01, 2026

Answer

Ensuring accessibility for images and multimedia in HTML involves using appropriate attributes and elements to provide alternative content for users who may not be able to see or hear the media. This includes using <alt> attributes for images and providing captions or transcripts for multimedia content.

Example Concept: To make images accessible, use the <img> tag with a descriptive alt attribute that conveys the purpose or content of the image. For multimedia, such as videos, use the <video> tag with <track> elements to include captions or subtitles, ensuring that users with hearing impairments can access the content.

Additional Comment:

The alt attribute should be concise but descriptive enough to convey the image's purpose.
For decorative images, an empty alt attribute (e.g., alt="") is appropriate to indicate they are not essential.
Use the <track> element within <video> to provide text tracks, like subtitles or captions, for accessibility.
