code: function resetStyle( element, prop, resetVal )
  	{
  		element.removeStyle( prop );
  		if ( element.getComputedStyle( prop ) != resetVal )
  			element.setStyle( prop, resetVal );
  	}
docs: We cannot just remove the style from the element, as it might be affected from non-inline stylesheets. To get the proper result, we should manually set the inline style to its default value.
