Div height problem

Hey, I have an annoying problem. On all of the windows computers ive tryed this on, i cant get a div's height go below 20(or around that). I can
on my mac, but i would like to know how to change on windows
it if its possible.

thanks.

you would have to change the font size in order to go smaller, a div with nothing in it will go the height of the font size even if you have the div set to less height

would that be like:



style="font-size:0;"



? And thank you for the help

yeah that would work but then y not just use a horizontal rule and use css to style it?
