Per game selectable Embed templates with fullscreen options

Hi, I was just messing around in the Chrome inspector and I found that if I change the style of the canvas object to something like this, it fills the screen rather nicely:

transform: translateZ(0px);
width: 100%;
left: 0px;
position: absolute;

So I thought maybe something like this could be a creator (or player) selectable option. There could be three templates, the default being the current, but two new ones: expand height and expand width. Above example would be expanded width.

Then either the game maker could select which template to use for each game, or a link / button to each option could be provided near the ‘Created with Flowlab’ text at the bottom.
