We tend to think of navigating a website as clicking from page-to-page via some kind of global navigation that’s always visible. When it comes to a single page, we often think scrolling is the one and only way to move from one end to the next.
Sometimes global navigation and scrolling are the best, most appropriate ways to move about, (however, they aren’t the only ways).
The websites in this article let you scroll, but they also provide alternative ways of finding cues and means for getting around. In several cases the designs encourage exploration, which is both more engaging and also teaches you how to navigate at the same time.
