I'm writing an app right now and I need to figure out what the width & height
of div, with it's applied CSS styling. Back in vanilla JS, there is the
function
[getComputedStyle()](https://developer.mozilla.org/en-US/docs/Web/API/Window/getComputedStyle)
which will give me
[CSSStyleDeclaration](https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleDeclaration)
object. That object is not part of the DOM or the BOM, it's part of the CSSOM.
I don't really know how to bind this. How would I go about this?
