Redesigned my own portfolio site to be be mobile-first, responsive, and lightweight. It is a fluid layout using percentages with two media query breakpoints at 38em and 56em. The idea being to make the design more forward compatible for mobile devices we have yet to see.
Glad you like the new design, Wilhelm, thanks!
Good point about the navigation arrow. I have added arrows to the first and last detail pages. I tried a lighter grey, but I think I like them the same color.
