Hi ,
What do you mean: if you canvas is outside of screen - then just reduce canvas size, or what?

seems the canvas can't be embded into another canvas. why not to use a div. 

Possible, you need to know the first canvas position, width & height, then try to register touchmove event on canvas 2&3, in the event callback to check the positon of canvas 2/3, compare with the first canvas position info, if it's out of the first canvas then set to 0 or any else.

Hello,

Try to use jCanvas plugin: http://projects.calebevans.me/jcanvas/ Probably it is something you are looking for.

Hello,

 

I checked the jCanvas that Palitsyna mentioned.

When I run the jCanvas, it is powerful and easy. That's why I also think it will be helpful to you.
