<bgsound>: The Background Sound element (obsolete) - HTML: HyperText Markup Language 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The Internet Explorer only HTML Background Sound element (<bgsound>) sets up a sound file to play in the background while the page is used; use <audio> instead.

Do not use this! In order to embed audio in a Web page, you should be using the <audio> element.

Attributes

balance

This attribute defines a number between -10,000 and +10,000 that determines how the volume will be divided between the speakers.

loop

This attribute indicates the number of times a sound is to be played and either has a numeric value or the keyword infinite.

src

This attribute specifies the URL of the sound file to be played, which must be one of the following types: .wav, .au, or .mid.

volume

This attribute defines a number between -10,000 and 0 that determines the loudness of a page's background sound.

Example

<bgsound src="sound1.mid">

<bgsound src="sound2.au" loop="infinite">

Usage notes

Historically, the <embed> element could be used with audio player plug-ins to play audio in the background in most browsers. However, even this is no longer appropriate, and you should use <audio> instead, since it's more capable, more compatible, and doesn't require plug-ins.

You can write <bgsound> as a self-closing tag (<bgsound />); however, since this element is non-standard, doing so will still not validate.

Browser compatibility
