Whats the best html design language for mobile apps?
That’s a question you’ll get lots of answers too, all vehemently defended.
Personally, I like Bootstrap 4 these days.
The good thing is that VoltBuilder is agnostic. It’s happy no matter what design language you choose.
You can use anything. So far I’ve relied on my own code only, so no framework for me.
I’ve developed a class for abstracting the most important HTML elements, e.g. to create lists, tables, selects etc based on data in arrays, and of course with implicit escaping of text etc.
The bottom menu looks simple enough to create on your own with some CSS and images, but maybe Vue or React supports such navigation.
