Embedding and Controlling Videos with the HTML5 `<video>` Element: A Comprehensive Guide
Learn how to seamlessly embed and control video playback in your web pages using the HTML5 `<video>` element. This tutorial covers using multiple video sources for browser compatibility, adding video controls, setting dimensions, and handling fallback content for enhanced user experience.
Embedding and Controlling Videos with the HTML5 `<video>` Element
Understanding the `<video>` Element
The HTML5 <video> element provides a straightforward way to embed video content directly into your web pages. This eliminates the need for browser plugins, improving security and simplifying web development. The browser will attempt to automatically select a compatible video format from the sources you provide. If the browser doesn't support the video tag, or if none of the provided video formats are compatible, a message will be shown to the user.
Basic Video Embedding
To embed a video, use the <video> element. Specify the video file using the `src` attribute. Include the `controls` attribute to display standard video controls (play, pause, volume, etc.) and the `width` and `height` attributes to set the player's dimensions, improving the user experience. Multiple video sources (`<source>` elements) are commonly used to provide various video formats to optimize browser compatibility.
Basic Video Embed Example
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
The text between the opening and closing <video> tags serves as fallback content for browsers that don't support the video element.
