Usage

Sass Variables

We provide timing functions which you can use with the animation or transition CSS properties

@use "@material/animation";

.my-element--animating {
  animation: foo-keyframe 175ms animation.$standard-curve-timing-function;
}

Variable	Description
$deceleration-curve-timing-function	Timing function to decelerate
$standard-curve-timing-function	Timing function to quickly accelerate and slowly decelerate
$acceleration-curve-timing-function	Timing function to accelerate
$sharp-curve-timing-function	Timing function to quickly accelerate and decelerate

The following functions create transitions given $name and the $duration. You can also specify $delay, but the default is 0ms. $name can either refer to the keyframe, or to CSS property used in transition.

@use "@material/animation";

.my-element {
  transition: animation.exit-permanent(/* $name: */ opacity, /* $duration: */ 175ms, /* $delay: */ 150ms);
  opacity: 0;
  will-change: opacity;

  &--animating {
    transition: animation.enter(/* $name: */ opacity, /* $duration: */ 175ms);
    opacity: 1;
  }
}

@use "@material/animation";

@keyframes fade-in {
  from {
    transform: translateY(-80px);
    opacity: 0;
  }

  to {
    transform: translateY(0);
    opacity: 1;
  }
}

.my-element {
  animation: animation.enter(/* $name: */ fade-in, /* $duration: */ 350ms);
}

Function	Description
enter($name, $duration, $delay)	Defines transition for entering the frame
exit-permanent($name, $duration, $delay)	Defines transition for exiting the frame permanently
exit-temporary($name, $duration, $delay)	Defines transition for exiting the frame temporarily
