Enter Google Slides: the product for your uncle Joe and aunt Lysa to create their own websites without knowing how to code!
I even have an example website for you that I made as it is a project that I'm working on in my free time. I already remade the website in actual HTML/CSS/JS but I was simply curious how well Google Slides would work. IMO, it has a thing or two over Sketch (such as displaying GIFs, having links) since I made the actual layout with Sketch, and then redid everything with Google Slides to do a side by side comparison (I went too far with this :P).
There are a few things to consider:
1. Every page needs to be made in its own slide show as you cannot have different document sizes.
2. You will be stuck with a slide viewer, but I figured for the industrious fellow, you could simply inject some JavaScript that disables that whole viewer when you iframe your Google Slides website.
3. There are zooming issues because the pages are of different document sizes.
4. The fact that you need to define document sizes is noteworthy in itself.
So yea, not super duper practical, unless you aren't a web designer and simply want a simple profile page online, but definitely weird :D
