When I create some custom graphics for a landing page, I don’t necessarily want to create an entirely new template. Since I’m really a one-man shop, I designed all our content templates to be very flexible, so I can do whatever I want within a certain area.
The page I’m referring to in the initial post is here: http://www.p2energysolutions.com/knowledge-center/securing-knowledge.
Could be that I’m not following best-practices, but it works for me, being the content creator, the graphics designer, and the webmaster. I also use divs in the content areas all the time – to float images, for example.
