Sounds like it might be a browser behavior issue. I've seen some really
weird behavior in browsers when a DOCTYPE is not declared at the start
of the web page. The doctype declaration and the version declared in it
are actually very important to the rendering and behavior of a web
page. Over the years, browser behavior has changed and will render code
and perform actions differently. The doctype declaration allows specify
which version behavior you are targeting.
So, is the first line of your web page something like:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">
