Handling multiple resolutions for mobile devices

[Shivendra Pratap Parmar]

I have built a game with predefined height and width of the game. My app is built using ionic framework. now when i call my game.start()  from iframe, it does not gets fully fit in the window. lime js scales down the game window. What should be the right direction so that game fully fits the window. should i have to set height and width for all possible resolutions, also is this the right approach .

Appreciate any help.
