HTML Video

HTML Video is an HTML element allowing you to embed video content directly within your web pages, adding visual dynamism and engagement. It opens up opportunities to incorporate diverse multimedia elements, enriching your website’s experience and storytelling.

Key elements of HTML Video:

  1. video tag: This is the central element for embedding video content. It typically contains one or more <source> elements and optional attributes like controls and autoplay.
  2. <source> tag: Similar to audio, nested <source> elements specify different video sources with various formats (e.g., MP4, WebM) to ensure playback compatibility across browsers.
  3. Attributes:
    • controls: Adds playback controls like play/pause, volume, and seek bar.
    • autoplay: Automatically starts playing the video as soon as the page loads (not recommended for user experience, browser support and accessibility).
    • poster: Defines an image to display before the video plays (often a thumbnail).
    • loop: Makes the video loop continuously.
