##Polymer.IronFitBehavior

`Polymer.IronFitBehavior` fits an element in another element using `max-height` and `max-width`, and optionally centers it in the window or another element.

The element will only be sized and/or positioned if it has not already been sized and/or positioned by CSS.

| CSS properties | Action | | --- | --- | | `position` set | Element is not centered horizontally or vertically | | `top` or `bottom` set | Element is not vertically centered | | `left` or `right` set | Element is not horizontally centered | | `max-height` set | Element respects `max-height` | | `max-width` set | Element respects `max-width` |

`Polymer.IronFitBehavior` can position an element into another element using `verticalAlign` and `horizontalAlign`. This will override the element's css position.

Use `noOverlap` to position the element around another element without overlapping it.
