"Underlines" as in URL links or in text styles?
If it's getting rid of the URL underline you're after, then make a style with zero bottom border and apply that to either
the DIV container or the BODY tage for the entire page.
Even better however is to make a style with dotted bottom 1px border with a bottom margin of maybe 2 px or .3ems
to make the dotted underline sit away from your type.
