On the Awwwards website, I really like the sticky action menu at the bottom of the page (the black rounded box on the screenshot)
I think it is :
- Close to the thumb on mobile, hence easy to reach
- Not too intrusive (less than some native-like menu that stays in this area to mimic mobile apps)
- Full of links when expanded, so content is relevant and the mobile screen constraint seems well handled
However, I doubt users know well how to use this kind of menu. What UX principles would advocate for or against this menu? Are there any recommendations or alternatives that have a similar set of features but are more common in UX? Are there examples of similar menus on other websites?
