This component will most likely be used with other polymer components. #### Properties `window-size`'s properties are: * `width`: window's width (window.innerWidth) * `height`: window's height (window.innerHeight) Since in most cases you can't change the size of a window in a browser via javascript (more info [here](https://developer.mozilla.org/en-US/docs/Web/API/Window/resizeTo)), the data bindings are unidirectional, i.e. flow upward (target to host) only. `window-size` is only active while it is attached to the document. #### Usage ```html ``` #### Notes This component is based on the new Polymer 2.0 Release Candidate. Whilst waiting for a "stable release" of Polymer 2, this component is a pre-release.
