XF 1.5 Format a disclaimer at the bottom of a page

I don't have the vocabulary to explain what I'm trying to do, so here's the best I can come up with:

I'm trying to have a disclaimer at the bottom of each page that looks like it's part of the site, offset in its own box.

Under vB this worked:

<div style="padding: $stylevar[cellpadding]px 0px 0px 0px">
  <table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
      <td class="thead" align="center">IMPORTANT DISCLAIMER</td>
      <td class="alt1" align="center">All my text goes here.</td>
But I can't figure out how to create a comparable display in Xenforo.
