Pretty dang nice long form scrolling page design for Adobe Muse. I like the side navigation that drives the page too, tab like design but with the fly out labels.
Microinteractions
Microinteractions are subtle site animations enhancing engagement. They include triggers, rules, feedback, and sometimes loops/modes. Practical uses: improving engagement, guiding user behavior. Well-designed microinteractions boost user engagement and your online presence.
Wonderful!
