Interesting, but only Keyboard app knows its actual height, and as far as we're introducing 3 party keyboard, there may be a 'fullscreen' keyboard implementation.
I am not sure if media query could cover the use case without fail. You don't want to use media query to record each keyboard app height in your app, right? So far an app window height is affected by: 1. Keyboard height (?) 2. Statusbar height (2rem to 4rem now) 3. Wrapper footer(the navigation UI) height (1rem to 5 or 6rem now) 4. Fullscreen state 5. Orientation state I am uncertain if we could judge 'now keyboard is there' from some math statement in media query. However it's a good idea to have: @media (-moz-keyboard) If we could have that!
