how can i remove the underline of the description?

Thanks for the quick response. I feel much comfortable using your product than Virtuemart, I can get a much better support from you instead of pulling my hair when I am stuck.

New questions is:

Q1: Right now all the category name or product description displays with the underline , see attached picture, how can I remove it? I don't want the underline show on the category or product name until the mouse points there .

Please advise if there is something to modify with the template or it's subject to Hikashop setting problem.

Q2: Under the production thumnail and description, there is "choose option", see image#2, how can i remove it?

Thank you!
