That is an extremely uninteresting website. It feels like someone used one of those UI kits to make it.
It's a shame because they're evidently a company with significant resource and funding (when you look at their open salary info) you'd think they might be able to push the limits a little more.
I wonder why they chose such a small max-width. To optimize across all screen sizes?
I've actually started to do this as well, I think it provides a good parity between small and large screen sizes. But, I don't like that they haven't constrained their header width at all. Bothers me when content is restricted and headers / footers are not.
Is your max-width usually this small?
The headers/footers are contained for me, at least on Chrome. I do like how some of the shapes float beyond the boundaries of the content.
I think this is useful information
