Working with our friends at Mogollon we just wrapped up Hadar Metal Design. Mogollon provided the clean industrial design and we did the rest in [valid] HTML 4.01 Strict and CSS.
We made use of JavaScript to perform in-page scrolling, where Flash might have otherwise been used. This keeps the content accessible to all users, and even better, to search engines, err I mean Google. We also tried to keep the markup as semantic as possible to give the site the best chance of being properly indexed with context. It’s probably not as pure as it could have been, we ended up using tables for the scrolling portions so we didn’t have to rely on endless browser hacks. Actually the CSS is relatively hack free.
