[Solved] IE Reserving Space for Invisible DIVs

Hello,
I have some text that is styled as follows:
visibility: hidden;
line-height: 0px;
font-size: 0px;

In Firefox, it is as if this text is completely invisible (it is inside a <p> tag), which is correct. In IE, however, a whole blank line is reserved for this text. How do I remove that extra whitespace for IE, but not change the results of the Firefox render?

Thanks,
Trevor
