HTML <video> Tag

The HTML 5 <video> tag is used to embed video on an HTML document. Browsers don't all support the same video formats, so you should provide multiple video formats for correct rendering. A path to the video file is nested inside <source> tag, or src attribute.

You can also include an alternate text in the <video> tag, that will be displayed in case if the browser doesn’t support the video format.

There are 3 supported video formats for the <video> element: MP4/MPEG 4, WebM, and Ogg. For the compression/decompression of large video files special programs, codecs, are used.

MP4/MPEG 4 files are used with H264 video and AAC audio codecs, WebM files - with VP8 video codec and Vorbis audio codec; and Ogg files - with Theora video codec and Vorbis audio codec.

Syntax

The <video> tag comes in pairs, its content is written between opening (<video>) and closing (</video>) tags.

Example

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
    <style>
      video {
        width: 300px; 
        height: 200px;
        border: 1px solid #666;
      }
    </style>
  </head>
