Extendible,
Composable

Working on a large team means ability to iterate is key

//----   timing  ----//
$class-slug: t !default;

@for $i from 1 through 7 {
  .#{$class-slug}-#{$i} {
    animation-duration: 0.8 - (0.1s * $i);
  }
}

Timing Increment

Like h1, h2

//----   ease  ----//
$easein-quad: cubic-bezier(0.55, 0.085, 0.68, 0.53);
$easeout-quad: cubic-bezier(0.25, 0.46, 0.45, 0.94);
$easein-back: cubic-bezier(.57, .07, .6, 1.71);
$easeout-back: cubic-bezier(0.175, 0.885, 0.32, 1.275);

Ease Variables

Brand-specific

.entrance {
  animation-timing-function: $easeout-quad;
}
.entrance-emphasis {
  animation-timing-function: $easeout-back;
}
.exit {
  animation-timing-function: $easein-quad;
}
.exit-emphasis {
  animation-timing-function: $easein-back;
}

Ease Reuse

Meaningful classes

//animations
@keyframes pop {
  0% {
    transform: scale(0.9) translateZ(0);
  }
  100% {
    transform: scale(1) translateZ(0);
  }
}

.pop {
  animation-name: pop;
  @extend .anim-fill-both;
}

Animations

Only what you need

.anim-fill-both {
  animation-fill-mode: both;
}

Extend/Mixins

Animation Fill Mode or Common Uses

Of  Note:

  • t5 is like h5- body copy
  • ~250ms is a good response time, under 400ms is under the doherty threshold (re-popularized by Halt and Catch Fire)
  • Hook into animation-play-state and native JS for single movements
  • Larger movements need components

Style and Branding:

Not one size fits all

Adhering to your branding means motion solves the problem for your users.

  • What happens repeatedly
  • Easing structures
  • User flow
  • Toggle on/off?

Style and Branding

Responsive

What needs to change, what doesn't

Mobile and Desktop compatible:

Zingtouch

Hammer

Draggable

Flickity

onMouseOver || onTouchStart

Responsive Interactions

Responsive Consistency

  • SVG is great for responsive
  • Canvas can be resolution-independant
  • Eases should stay the same, but timing can be adjusted
  • Specify initial-scale=1.0 in the meta tag so that the device is not waiting the required 300ms
  • Must either start from a larger touch-target (40px x 40px or greater) or use @media(pointer:coarse)as support allows

  • Opacity
  • Transforms
  • Hardware Acceleration
@mixin accelerate() {
 transform: translateZ(0);
 backface-visibility: hidden;
 perspective: 1000px;
}

.foo {
  @include accelerate(transform);
}
