-Note that the `onbeforeremove` hook only fires on the element that loses its `parentNode` when an elements gets detached from the DOM. This behavior is by design and exists to prevent a potential jarring user experience where every conceivable exit animation on the page would run on a route change.

 When creating animations, it's recommended that you only use the `opacity` and `transform` CSS rules, since these can be hardware-accelerated by modern browsers and yield better performance than animating `top`, `left`, `width`, and `height`.
 
-It's also recommended that you avoid the `box-shadow` rule and selectors like `:nth-child`, since these are also resource intensive options. Other things that can be expensive include large or dynamically scaled images and overlapping elements with different `position` values (e.g. an absolute postioned element over a fixed element).
