Okay, thanks. That vertically-aligned example did the trick! Now I know how to proceed.

It appears the answer is "No, you cannot eliminate that Div tag added to every Element (or element pair, such as Input/Label)".

Instead, you must add extra grouping tags (Div, span, whatever) where you CAN control the class name with attributes, outside (surrounding) those elements. Then it is just a matter of targeting your CSS to those selectors.

Thanks for the quick replies, and the solution!
