Does absolute positioning using inline styles work correctly when converting html to PDF, or is this not fully supported?

Can you tell me why this HTML doesn't seem to work? I am trying to generate 2 pages using page-break-before:always on the second one. They use the same position, but shouldn't the position being used be relative to the page? The second parent div seems to be overlapping the first. Thanks!

<div style="position:relative;">
<div style="position:absolute;left:170;top:20;">Form 1</div>
<div style="width:100%;background:#000000;color:#ffffff;padding:2px 4px 2px 4px;position:absolute;left:0;top:60;">Section A. Administrative</div>
<div style="position:absolute;left:30;top:120;">1)Date of visit:</div>
<div style="position:absolute;left:150;top:120;color:#003399;font-style:italic;">05/19/1984</div>
</div>

<div style="position:relative;page-break-before:always;">
<div style="position:absolute;left:170;top:20;">Form 2</div>
<div style="width:100%;background:#000000;color:#ffffff;padding:2px 4px 2px 4px;position:absolute;left:0;top:60;">Section A. Administrative</div>
<div style="position:absolute;left:30;top:120;">1)Date of visit:</div>
<div style="position:absolute;left:150;top:120;color:#003399;font-style:italic;">12/16/1991</div>
</div>

Thank you. I figured out what is going wrong. It is working how I wanted to, the absolute positioned divs are relative to the parent div, which starts a new page. But I didn't assign the parent div a height, and since absolute position elements are floating, the parent div won't grow to accomodate them. I assigned a height to the parent div and it works correctly now.
