To find the template name - vboptions > General Settings > Add Template Name in HTML Comments > set to Yes . Then go back to your page and view the source code and you will see the name of the template called around your part of the code. Sometimes the template is the one mentioned at the very top of the page source.
However, I'm guessing you mean style? Check the name of the style in your Styles & Templates area and then do a search for the name in google.
