I am currently designing a website for my client. I decided to use Sketch to prepare artboards and Invision web app to prototype and present it.
During the designing process I planned for some portions of the site to feature parallax scrolling. I have an element partially overlapped by element on top of it, and it will get more and more visible after the user scrolls down.
Now, how do I show it to client? It is only a design, so I don't want to assemble it on testing enviroment, as I am not sure he will like it and decide to use that design choice anyway, but if it's static, all he'll see is some overlap, obscuring important elements.
In this instance my issue is with parallax scrolling, but this can be easily asked about other elements, like video headers, or onhover buttons. Is there a way to present it as a self-explanatory, coherent design?
