https://scratch.mit.edu for an introduction to programming your young people.

For simple cross platform maybe gamesalad.com

Thanks. I have a young relative that uses Scratch.

My kid has played a few different iOS games that are made to teach programming basics to kids (Hopscotch, Light Bot, etc).

I've also created some simple CSS animation stuff on CodePen for them to mess with colors, speed, etc.

I haven't heard of Gamesalad, I'll check that out.
