# Motion

Universal classes and helpers to manage transitions and animations.

All animations and transitions inherit (by default) from a core set of timings. There are two speeds, and several timing curves:

$transition: (
  fast-out-slow-in: cubic-bezier(0.4, 0, 0.2, 1),
  linear-out-slow-in: cubic-bezier(0, 0, 0.2, 1),
  fast-out-linear-in: cubic-bezier(0.4, 0, 1, 1),
  ease-in-out: cubic-bezier(0.4, 0, 0.6, 1),
  fast-in-fast-out: cubic-bezier(0.25, 0.8, 0.25, 1),
  swing: cubic-bezier(0.25, 0.8, 0.5, 1),

$transition-durations: (
  snap: .1s,
  fast: .165s,
  brisk: .333s,
  slow: .5s,
  sleepy: 1s,

$primary-transition: 0.165s map-get($transition, swing) !default;
$secondary-transition: 0.3s map-get($transition, ease-in-out) !default;

# Animations

Our animation classes are prefixed with fx- to denote them as such. They are grouped according to those that need the user's attention, and those that indicate system activity. See the notifications documentation for additional details.

# Attention-getting

Name Class Details
shake .fx-shake
pulse .fx-pulse

# Loading

spin .fx-spin

# Transitions

# Global

(none, at present)

# Vue-specific

These classes are written such that they may be consumed by a Vue <transition>. Currently, there are:

  • scale
  • slide-{x|y}
  • fade
