Hiya,
All appears OK now, - I assume you removed that style alteration.
One wouldn't normally touch the 'html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6' style - this is just a generic set of rules for cross-browser consistency. A style change here could have wide reaching effects!
If you need help with the appearance of a particular element, post back here.
