Post #205546 is what’s causing the bottom of this page to display strangely.
It is using the <li> (list item) tag without being preceded by either the <ol> (ordered list) or <ul> (unordered list) tags, followed by a closing tag of the same type (</ol> or </ul>).
For whatever reason, this throws off the display for the rest of the page – it’s happened before.
Specifically, if you edit that post to remove this line:
<li> hi </li>
…the display should then go back to normal.
