Sometimes I have trouble with blogger hacks that don't work well in all browsers. I don't understand why this happens, but my daugher just noticed yesterday that the Dead Language Latin Club blog that we set up (and which looks rather nice in Internet Explorer) looks really strange in Firefox right now. The posts are up against the left side of the screen and the sidebar is all the way on the right. I think that the problem came about from widening the margins, but I'll have to dig in and experiment to try to fix it.
Any wisdom on why this happens and how to avoid it would be much appreciated. :)
