I was browsing the page https://www.wix.com/code/home/example/Hide-and-Show-Elements and the custom effects are awesome. Do they work on mobile as well?
Wix code works on mobile and the coding features in this example work as well.
However, like anything else with mobile, you will need to adjust your layout and the positioning of elements to get the right experience on mobile (like position elements on top of each other to get the right effects).
