Hi there, yes those button animations are created in Edge. In terms of embedding, they are using iFrames for each button- below is an example embedd for one of the buttons, where you can see the Edge embed:
On first load, I got a bunch of js errors, and those Edge iFrames didn't load. After refreshing they all loaded fine.
In terms of animating the buttons, that is very straightforward. Create a symbol, add "in" and "out" labels, and add "mouseover" and "mouseout" events, telling the symbol to play from a specific label at each event.
Thak you very much man, now i have the button!
now, how can i put it into adobe muse?
