Site-wide Navbar in phpbb3

[Grub-Xer0]

Alright, so my site's index.php contains an include to my header.html, which is styled by a separate CSS. I am using phpbb3 as my forum software and I am trying to include that same header file into my forum index to create a centralized horizontal navigation bar all around.

I don't want to use an iframe. I have tried copying the header contents to the forum's overall_header.html file, then added the same CSS to the theme's stylesheet, but the header became disfigured. I have tried to create a separate class for the css, but to no avail. So is there any way I can include an html from my site root and style it?

The first picture is my site index, the second picture is what I am trying to achieve.

This is the include that the main page has for the header:

<?php
include "$_SERVER[DOCUMENT_ROOT]/includes/header.html";
?>

This is the header.html:

<div id="header">
<center>
<table class="header" width="927" border="0">
<tr>
<td><a href="http://www.teh-non.com/"><img src="/images/non_logo.png"></a></td>

<td valign="bottom">
<ul>
  <li><a href="http://www.teh-non.com/">Home</a></li>
  <li><a href="http://www.teh-non.com/bbs">Forums</a></li>
  <li><a href="http://www.teh-non.com/vidya">Stream</a></li>
  <li><a href="http://multitwitch.tv/grubxer0/parlux" target="new">Dual Stream</a></li>
  <li><a href="http://www.teh-non.com/minecraft">Minecraft</a></li>
</ul>
</td>
</tr>
</table>
</center>
</div>

The CSS:

#header ul li a:link, #header ul li a:visited {
    display: block;
    width: 120px;
    font-weight: bold;
    color: #000000;
    background-color: #9933FF;
    text-align: center;
    padding: 3px;
    text-decoration: none;
    text-transform: uppercase;
    font: arial;
}

#header ul li a:hover, #header ul li a:active {
    background-color: #B870FF;
    text-decoration: none;
}

I've been trying to figure out a way to include [root]/includes/header.html to the overall_header using

<!-- INCLUDE overall_header.html -->

, but nothing even shows up.
