HELP Weirdest Thing happened with my website. CSS menu

Hello everybody, I'm new on this CSS style, i haven't touch web designing for a while because my major involves more programming, however, i'm having trouble with CSS with browser compatibility. The weirdest thing is that the Menu i did to the gallery of the websites was working fine a few days ago on all three browsers i tested which where IE, Firefox, and Chrome. However, no w only IE displays the menu correctly, and all that happened without me touching any codes at all. if someone would please let me know what could be possible be wrong. This is the URL

http://www.luisgeneralcontractor.net/eng/gallery.php

this is the COde on the CSS

#menu5 {
     display: block;
	width:92%;
        height: 300px
	border-style: solid solid none solid;
	border-color: #000;
	border-width: 0px;
		margin: 1px 1px 1px 0px;

}
#menu5 ul {
	list-style: none;
	margin: 0;
	padding: 10px;
}
#menu5  a {
	height: 32px;
	width: 100%;
	text-decoration: none;
	background:  url(swf/menu4.gif);
	padding: 8px 0px 0px 10px;
	color: #CCC;
	display: block;
	filter:alpha(opacity=100);
	-moz-opacity:1;
	opacity:1;
}

#menu5  a:link, #menu5  a:visited {
	color: #CCC;
	display: inline;
	background:  url(swf/menu4.gif);
	padding: 8px 0px 0px 10px;
	filter:alpha(opacity=100);
	-moz-opacity:1;
	opacity:1;
}

#menu5  a:hover, #menu5 #current  {
	color: #000000;
	background:  url(swf/fon4.gif);
	padding: 8px 0px 0px 10px;
}

I see the same style/performance in ie7/safari/ff3, what's the problem?

Is it that kitchen 'n bathroom stays highlighted?
