FAQ
1. What formats do I need for maximum compatibility?
For maximum compatibility, consider providing MP4, WebM, and Ogg formats.
2. Can I use the video tag without controls?
Yes, if the controls attribute is omitted, the video will play without user interface controls, but this is not recommended for accessibility.
3. Is it necessary to provide fallback content?
While it’s not strictly necessary, providing fallback content ensures that all users will have some information if their browser doesn’t support the video tag.
4. How can I ensure my videos are responsive?
Use CSS to set the width to 100% and height to auto for responsive designs:
.video-container {
width: 100%;
height: auto;
}
5. Can I load videos from external sources like YouTube?
While the video tag only supports direct file sources, embedding videos from platforms like YouTube is typically done using the iframe tag instead.
