I would like to make games that can run from the Web browser of computers and phone browsers. I tested a demo game, exported to html5 and put it on a Web server. The game runs OK on the Web browser of computers. However, when I load the game from a smart phone, the game window is very small and not resize-able. If I rotate the phone, the size of the game window does not change.
So my question is how to make a full screen game or a resize-able game on phone browser?
