How do I make a memory game scalable?

I have created the memeorygame for the tutorial.

Now I find it very hard to create an html5 thats shows the game in the correct dimensions on laptop, tablet and phone.

Am I doing something wrong?

a zipped source files are avaiable at: drkoops.nl/gamedidactiek/BuilUpMemory1.0.zip

I would be very grateful to learn how to solve this problem.

You can dynamically scale all of your assets to fit any screen.

A curious side effect of this is that it effectively disables the ctrl-mouse wheel zoom in a browser.

Thanks for the reply.

I appreciate it greatly

Finally find some time to look into it.
