< bgsound > (Background Sound)
This Internet Explorer element associates a background sound with a page.
Standard Syntax (Defined by Internet Explorer 4)
<bgsound balance="number" id="unique alphanumeric identifier" loop="number" src="url of sound file" volume="number">
Events Defined by Internet Explorer
onlayoutcomplete, onmouseenter, onmouseleave, onreadystatechange
Element-Specific 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 positive numeric value or -1 to specify that it will continuously loop. The keyword infinite is also supported in many Internet Explorer implementations .
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.
Examples
<bgsound src="sound1.mid"> <bgsound src="sound2.au" loop="infinite">

Notes
-
Similar functionality can be achieved in some versions of Netscape using the <embed> tag to invoke an audio player.
-
You can write bgsound with a self-closing tag <bgsound /> . However, since this element is not part of a standard, making it XHTML-like will not make it validate.

bgcolor This attribute sets the background color for the document. Its value can be either a browser-dependent named color or a color specified using the hexadecimal #RRGGBB format.
bgproperties This attribute, first introduced in Internet Explorer 2, has one value, fixed , which causes the background image to act as a fixed watermark and not to scroll.

marginheight This Netscape-specific attribute sets the top margin for the document in pixels. If set to or " " , the top margin will be exactly on the top edge of the window or frame. It is equivalent to combining the Internet Explorer attributes bottommargin and topmargin .
marginwidth This Netscape-specific attribute sets the left and right margins for the page in pixels, overriding the default margin. When set to or " " , the left margin is the left edge of the window or the frame. It is equivalent to combining the Internet Explorer attributes leftmargin and rightmargin .
nowrap This Internet Explorer-specific attribute is used to control the wrapping of text body width. If set to yes , text should not wrap. The default is no . CSS rules should be used instead of this attribute.

Notes
-
When defining text colors, it is important to be careful to specify both foreground and background explicitly so that they are not masked out by browser defaults set by the user .
-
Under the strict HTML and XHTML definitions, CSS should be used in place of presentation attributes like alink , background , bgcolor , link , text , and vlink .
-
This element must be present in all documents except those declaring a frame set.
-
Under XHTML 1.0, the closing </body> tag is mandatory.
<br> (Line Break)
This empty element forces a line break.
Standard Syntax
<br class="class name(s)" clear="all left none right" (transitional only) id="unique alphanumeric identifier" style="style information" title="advisory text" />
Events Defined by Internet Explorer
onlayoutcomplete, onlosecapture, onreadystatechange
Element-Specific Attributes
clear This attribute forces the insertion of vertical space so that the tagged text can be positioned with respect to images. A value of left clears text that flows around left-aligned images to the next full left margin, a value of right clears text that flows around right-aligned images to the next full right margin, and a value of all clears text until it can reach both full margins. The default value according to the transitional HTML and XHTML specifications is none , but its meaning generally is supported as just introducing a return and nothing more.
Examples
This text will be broken here <br /> and continued on a new line. <img src="test.gif" align="right" /> This is the image caption. <br clear="right" />
Compatibility
| HTML 2, 3.2, 4, 4.01 | Internet Explorer 2, 3, 4, 5, 5.5, 6 |
Notes
-
This is an empty element. A closing tag is illegal under all HTML specifications. For XHTML compatibility, a closing slash is required: <br /> .
-
Under the strict HTML and XHTML specifications, the clear attribute is not valid. The style property clear provides the same functionality as the clear attribute.
