I hope this is not too basic to be off-topic, but I am wondering to what extent it is possible to customize WordPress to fit an existing design. I have a design in mind and read somewhere (WordPress manuals?) that it is possible to only manage a small part of a website with WordPress and then slowly migrate the whole site to be WordPress-managed. If one would like to preserve a certain design, is this preferred to tweaking WordPress templates? That is to say, should I start from a website and slowly move into WordPress, or should I start from the WordPress template, and try to tweak it until I arrive at the design I want. Are there any examples of WordPress sites, which fall into light-weight (but image heavy) websites, which exhibit freedom from the WordPress mold? (Is this too vague?)
