How do you embed audio and video with fallback controls?

Use <audio> or <video> tags with the controls attribute for native playback UI, and provide multiple <source> elements with different formats for cross-browser compatibility, plus fallback text for unsupported browsers.

Example
<video controls width="400" poster="thumb.jpg">
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.webm" type="video/webm">
  Your browser does not support video.
</video>
