@react-md/transition

Create simple CSS transitions using the provided transition hooks and components utilizing the default transition timing functions. This package also provides a collapse transition, scaling transition, vertical only scaling transition, and a new page transition named cross fade.

Provided components and hooks:

• Collapse or useCollapseTransition - transition an element in and out of view based on the height of the element
• CrossFade or useCrossFadeTransition - a transition generally used for a full page transition that fades and slightly moves a child component into view
• ScaleTransition or useScaleTransition - transition an element in and out of view with a scale transform that can be updated to just be scaleY
• useTransition - a hook implementation of the Transition component from react-transition-group
• CSSTransition or useCSSTransition - allows for a CSS transition that was heavily inspired by react-transition-group
• useFixedPositioning - hooks into the CSSTransition component from to fix an element to another element within the viewport

The rmd-transition-shadow-transition mixin allows you to "performantly" transition between two box shadow values using the opacity trick. This mixin automatically creates a pseudo ::before or ::after element with the final box shadow and animates the opacity once one of the $active-selectors are triggered. The code below will help explain this part a bit more.
