Issue #120  (Screen API and Learning Tools)11/05/15

The global window object gives you access to a Screen interface, or screen object, that lets you access various values that give you info on the current window. Here is what the object looks like if you log it out on JS Bin or in the Dev tools using window.screen:
[object Screen] {
  availHeight: 1040,
  availLeft: 0,
  availTop: 0,
  availWidth: 1920,
  colorDepth: 24,
  height: 1080,
  orientation: [object ScreenOrientation] {
  pixelDepth: 24,
  width: 1920

I've abbreviated the "orientation" section, but as you can see, you get values that include information about the height and width of the window, the color depth, and pixel depth. These would be accessible via window.screen.availWidth, window.screen.pixelDepth, etc. (of course, the window object is global, so you could omit it).

The orientation property is present on Chrome but not Firefox. Firefox uses mozOrientation and instead of this being an object with its own properties and methods, it's the equivalent of Chrome's screen.orientation.type property. So aside from the major differences in the orientation interface, the basic properties of the Screen API seem to be usable in all browsers.
