Elements realigning is a good strategy to get a style update when redesigning a complex website such as XWiki.org. Since the website is an umbrella for many subdomains, they are individualized by using different color themes. Other key pages (like the Download section) were redone from scratch, focusing on simplifying and clarifying the process. XWiki is an extensible open source platform for developing collaborative applications on top of the wiki paradigm.

I prefer to interact and create the design in the environment it will live in, so I usually code my prototypes directly in HTML+CSS.
