The monthly tournaments page (http://littlegolem.net/jsp/games/gamedetail.jsp?gtid=havannah&page=mc) features a left column that is not quite wide enough to fit September on it, so the text wraps, with the result that some lines are taller than others.

The culprit seems to be the inline style on the first row's , which has a width of 100 px;. Setting it to 105px; worked for me, but deleting it actually worked just as well.

For some reason, the words “inline style” are not showing in that message.

Rather, it's not inline style that's missing, it's that the forum software stripped my tags. It's the that has the inline style.
