Try this:

.testmarkup {
	color: #FFF;
	font-weight: bold;
	font-size: 10px;
	font-family: Verdana, Arial, Helvetica, sans-serif;
	text-decoration: none;
}

EDIT:

I think I just noticed where your main problem is..

When you were doing the spans, you had the font set to 10px.. when you put it in the style it was set for 10pt.

Perhaps just changing that back to 10px is the answer to the problem.
