You make a lot of trade-offs by picking either Canvas or the DOM to render your web app. If you do pick the DOM you will probably abstract out all the DOM operations anyway. But if you pick the Canvas you have to implement everything yourself. With DOM you can do very nice stuff using CSS. The browser (DOM) comes with everything you need "out of the box", but interacting with the DOM, and make it do stuff that are not specified - it will be very "hacky", and you have to deal with different browsers (mobile browsers) working differently.
