vertical centering

Please view the attached image to understand my problem. I want to vertically center the text, the information image as well as the two buttons.

Code snippet:

<div class="ui-box-top" style="padding: 0 !important; height: 35px;">
    Login
</div>
<div class="ui-box-content">
 
    <div class="quickform"><form method="post" id="login" action="index.php"><div><input type="hidden" name="_qf__login" id="_qf__login-0" />
<fieldset id="qfauto-0"><legend id="qfauto-0-legend">Login</legend>

I'm trying to create a horizontal navigation bar for the top of my page. I need to make each link in the bar 40px heigh and 75 wide to fit a background image to each link.

To do this I need to centre the text vertically to make it correctly line up. Currently I have this (I haven't added in any of the background images yet)

#navBar {
	margin: 0px;
	padding: 0px;
	width: 800px;
	clear: both;
	float: left;
}
#navBar ul {
	list-style-type: none;
	margin: 0px;
	padding: 0px;
}
#navBar ul li {
	border: thin dotted #000;
	height: 40px;
	width: auto;
	float: left;
}

Hello everybody!

So I have this problem with centering vertically. I found this page about vertical-centering-with-css but none of these 5 posibilities solves my problem.

I have a div#mapAndQuestions in which I have a

on the left side and a image on the right side.

div#mapAndQuestions
{
height:60%;
min-height:200px;
}

so this div#mapAndQuestions resizes whenever the browser windows is being resized but it stops ar 200px;

and
ul#questions
{
height: 300px;
display:table-cell;

I'm new to this CSS stuff. I'm trying to position a DIV TAG exactly in the center of the page. I want it to move with the actual page, ie be centered within the browser. For some reason, I cannot get the TAG properties to conform to the specifics im trying to give it. Also, on top of that, the FORM that i'm trying to embed within the TAG is not showing up whatsoever. Does anyone know what the hell I'm doing wrong? Any help would be amazing.
