HTML5 standalone app with fullscreen custom resolution

I've been searching online and i can't really seem to find an answer.

Does somewhere out there exist basically a lite-weight web browser / app run-time, that allows you to set custom stuff like antialiasing (that should be available in NWJS via args, right?), render resolution etc...

I know about NWJS and Electron (that both use chromium), but AFAIK - there is no option for custom res full-screen run.

For the time being i care only for desktop, no mobile.

Please refrain from question: "Why?", "Why not choose different approach?"

It's more of a matter of "Can it be done with HTML|CSS|JS, though" concept.
(I have made an audio visualizer utilizing css animations, transitions, filters and so on... On weaker GPUs it performed badly - as expected. Now I think about creating a simple concept game, using purely power of js, css and htmlDOM - no canvas... I think "Chrome Racer" was also done without jsCanvas)

Thank you for any reasonable input.
