Drop Down Menus different in IE and FF

[hauser]

Hi. I'm creating a website with iWeb. I used dynamic drive codes to create a elementary school website with horizontal drop down menus at the top of the website. The menus look fine on Firefox and Safari, but the entire menu is different on IE. Here's the website address:

http://nestleweb.com/Welcome_Home.html

Here is the code I used. Can anyone tell me what's going on with IE? I really don't understand css/html too well.

<style type="text/css">

/*Credits: Dynamic Drive CSS Library */
/*URL: http://www.dynamicdrive.com/style/ */

.suckertreemenu ul{
margin: 1;
padding: 0;
list-style-type: none;
}

/*Top level list items*/
.suckertreemenu ul li{
position: relative;
display: inline;
float: left;
background-color: #F3F3F3; /*overall menu background color*/
}

/*Top level menu link items style*/
.suckertreemenu ul li a{
display: block;
width: 90x; /*Width of top level menu link items*/
padding: 5px 20px;
border: 2px solid black;
border-center-width: 1;
text-decoration: none;
color: blue;
}
	
/*1st sub level menu*/
.suckertreemenu ul li ul{
left: 0;
position: absolute;
top: 1em; /* no need to change, as true value set by script */
display: block;
visibility: hidden;
}

/*Sub level menu list items (undo style from Top level List Items)*/
.suckertreemenu ul li ul li{
display: list-item;
float: none;
}

/*All subsequent sub menu levels offset after 1st level sub menu */
.suckertreemenu ul li ul li ul{ 
left: 159px; /* no need to change, as true value set by script */
top: 0;
}

/* Sub level menu links style */
.suckertreemenu ul li ul li a{
display: block;
width: 160px; /*width of sub menu levels*/
color: navy;
text-decoration: none;
padding: 1px 5px;
border: 1px solid #ccc;
}

.suckertreemenu ul li a:hover{
background-color: black;
color: white;
}

/*Background image for top level menu list links */
.suckertreemenu .mainfoldericon{
background: #F3F3F3 url(media/arrow-down.gif) no-repeat center right;
}

/*Background image for subsequent level menu list links */
.suckertreemenu .subfoldericon{
background: #F3F3F3 url(media/arrow-right.gif) no-repeat center right;
}

* html p#iepara{ /*For a paragraph (if any) that immediately follows suckertree menu, add 1em top spacing between the two in IE*/
padding-top: 1em;
}
	
/* Holly Hack for IE \*/
* html .suckertreemenu ul li { float: left; height: 1%; }
* html .suckertreemenu ul li a { height: 1%; }
/* End */

</style>

That's IE for you...

Not to give you any more problems, but the menu's too big in Firefox, on Linux (See attached).
