Making Media Fallback Work in HTML
In HTML, when embedding media with <video> or <audio>, you can provide fallback content that appears if the browser does not support the element or the provided file formats.
Use multiple
<source>elements to supply different formats (e.g., MP4, WebM, Ogg for video; MP3, OGG, WAV for audio).Add text inside the
<video>or<audio>tags — this text is displayed when the media cannot be played.Include a download link so users can access the file even if playback fails.
For very old browsers, you can embed a Flash player or external plugin as an extra fallback (rarely needed today).
In short: Always include multiple formats using <source> and add fallback text or links so users can still access your media if their browser doesn’t support direct playback.
