The align attribute is deprecated. If you had searched the forum (or the web), you would have found that the proper way to align an element is to set its left and right margins to "auto" using CSS. For IE6, you need to set "text-align" on the element's parent to "center".
HTML Code:
<html>
<head>
<style type="text/css">
#Parent {
text-align: center;
}
#Child {
margin: auto;
width: 50%;
}
</style>
</head>
<body>
<div id="Parent">
<p id="Child">
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec fermentum orci nec felis. Sed sollicitudin diam id sapien. Ut libero. Vestibulum quam libero, malesuada et, ornare id, aliquet id, tellus.
</p>
</div>
</body>
</html>
Frontpage produces terrible code. Better to use a text editor.
Despite what MSDN says, <bgsound> needs to be closed. Every element should be closed. <bgsound> is also MS proprietary and only supported by IE, for which I'm thankful (I don't want music that I can't stop). A more usable design is to use a media player, something that gives the user control over over playing sound. Also, compress the sound as MP3s; WAVs are too much of a drain on the network.
While you're at it, strongly consider dropping the intro page. Intro pages (and background music) are both considered design mistakes (mistakes 3 and 14). The former delays the user's access to whatever zhe's looking for while the latter doesn't give the user control over something zhe should be able to control. Music is acceptable on a page if it's a band page and, as stated earlier, you use a media player so the user can start and stop the music and change the song.
Of all browser plugins, Java is the most likely to be disabled. If you must use a plugin for content, flash is much more likely to be installed and enabled (though some people use e.g. flashblock to block flash content). A search control should not be rely on plugins; it should work when HTML is the only technology used client side.
Your choice of background image and text color for the main page clash, making it hard to read.
Most of the source code is your menu scripting. To make the pages load faster (and take advantage of caching), use CSS menus, such as Mark Wilton-Jones' Pure CSS menus or Sons of Suckerfish.
What's up with those paragraphs of nothing but non breaking spaces ( )? Are you using them as spacers? Terrible implementation; use CSS margins and padding.
