Three column header using floating elements - html

Question

What the Header Should Look Like
This is how the header should look like.
What it currently looks like
As you can see, my header isn't looking too good... I seem to be having some floating issues.
Current Header Code
Here is the HMTL I used to generate my header.
I'm trying to center the h1, float the logo to the left completely and have the h2 display beside the logo. The publish date and publisher are fine.
<header>
<ul style="list-style-type:none;float:right;">
<li style="float:left;">
<img src="C:\Logo.jpg" alt="Logo"/>
</li>
<li style="float:left;">
<h2>Statuts de Production</h2>
</li>
<li style="float:right;">
<h1 style="margin-bottom:0px">Machines en cours d'assemblage</h1>
</li>
<ul style="list-style-type:none;float:right;">
<li>
Dernière mise à jour: <xsl:value-of select="Table/Publish/DateEntry"/>
</li>
<li>
Par: <xsl:value-of select="Table/Publish/Username"/>
</li>
</ul>
</ul>
</header>
Am I not using the right approach? Should I use a table instead of an unordered list?

Answer 1

If you want to vertical align the list items and indent the middle one, just remove the styles from the HTML and use this external CSS (using external CSS is the first thing to improve your approach):
ul { display: block; list-style-type:none; height: 50px; }
li { display: inline-block; vertical-align: middle; }
ul ul { display: inline-block; }
ul ul li { display: block; }
and set the padding to each list item as you want, the third item might be floated right.
Second: you can not use image path on your HDD C:\Logo.jpg to enable the access from clients, use the http://... protocol.
Third: you can not use ul as direct child of ul. Only lis are allowed inside ul
<ul>
<li>item 1</li>
<li>item 2</li>
<li>
<ul>
<li>subitem 1</li>
<li>subitem 2</li>
</ul>
</li>
</ul>

Dose the following help you? it is designed such that the hight is constant.
<div style='position:relative; padding:0px 200px 0px 200px; background-color:gray;height:20px;box-sizing:border-box;'>
<div style='position:absolute;background-color:yellow; left:0px; top:0px; height:100%;width:200px;'>
left pannel
</div>
<div style='position:absolute;background-color:yellow; right:0px; top:0px; height:100%; width:200px;'>
right pannel.
</div>
<div style='box-sizing:border-box;width:100%;text-align:center;'>
Center
</div>
</div>
