CSS problems with rq24

Eric,

Something odd is happening for the CSS in rq24.

In Firefox, I do not get the green background and border around pre.data - the 
text is indented more than I'd expect though.

Other things nested inside a div.exampleGroup do display correctly.

pre.dataExtract (which are not nested in div.exampleGroup works).

It does display correctly in Internet Explorer.

I'v includes a quick hack that seems to make it work: I copied the definition 
of pre.data into rq24 <style>.
