Semantic media elements in HTML make it easier to present images, audio, and video in a clear and accessible way. They help structure your content so that both users and assistive technologies can better understand it.

The figure and figcaption elements work together to group media with captions. This pairing provides meaningful context, explaining what an image or video represents without relying only on surrounding text.

The img element displays images, but it's essential to include an alt attribute with short, descriptive text. This ensures that users who rely on screen readers or those with images disabled still receive the same information.

For multimedia, the audio and video elements offer built-in playback support. You can also include captions or transcripts to make your content accessible to all users.

Using these semantic elements properly improves your page's structure, accessibility, and overall user experience.
