I want to know how can we know which language joomla,wordpress, etc this site http://purepowerbootcamp.com/sitemap/index.htm is built with, and what template they are using?
No template used here buddy, it has been designed in Dreamweaver and uses the template feature in Dreamweaver (.dwt file extension) to save from repeating the design.
If in anycase they use a template..you can go thru their source code there are some copyright statements and stuff..u might find the name of the template there
