Exporting html canvas animation from Flash CC... responsive?

When exporting animation from Flash CC as html5, can you make the resulting code resposive?

Looked at the html + tried changing:

<canvas id="canvas" width="980" height="579" style="background-color:#5F5F5F"></canvas>

to

<canvas id="canvas" width="100%" height="100%" style="background-color:#5F5F5F"></canvas>

as well as trying "exactfit" and "*", etc.. But each of these attempts result in a size malfunction.

It would be great to be able to export html5 animation from Flash and have some means of making them responsive. Maybe it's easier to do this with Edge Animate - but can it be done with Flash, too?

Thanks!
