Everyone who touches UI,
needs to have motion skills.

From interaction to visual to front-end designers

Creatures of habit

By nature we problem solve and connect patterns.

We want to understand.

Motion can help connect patterns!

Three simplistic movement
principles that I try to stick to:

It becomes it.

It's already on the screen, why reintroduce it?

Just show the thing.

Content is Batman, motion is Robin. Don't make it the star.

Create wonder.

Where possible, make it magical.

What does motion mean to you?

What about for the things you build?

You'll have to figure this out ☺

Today we're going to move interface
elements in these ways:

Position / Translate

Scale

Rotation

Opacity

Anchor / Origin

Disney Animation: The Illusion of Life

Printed in 1981; 489 pages.

The 12 basic principles of animation

Squash and stretch

Adds a bit of realism to an otherwise static interface.

Example:

Anticipation

A subtle hesitation before the main movement.

Example:

Pose to pose

Block out states of what you're animating.
This is good planning.

Example:

Follow through

Moving past the elements destination and coming back.

Example:

Exaggeration

Movement that helps get your attention.

Example:

Slow in and slow out

A natural movement with more frames
at the start and end of a movement.

Arcs

Consistent and predictable motion of your product.

Secondary action

Surrounding elements that play off of the main movement.

Timing

Be quick about it. This takes some practice.

Let's do this!

How we typically feel
after posting work to dribbble...

I do this... and you should too.

Shoot work that you give developers

Example #1: Salesforce1, Publisher

Worked with one of our iOS devs:

Some publisher specs

AFX animation

Same AFX file, different composition

Example #2: Salesforce1, Onboarding

Worked with another awesome iOS dev:

The flow aka a storyboard ☺

The AFX animation

What will we be doing?

• Using what we just made, let's make a GIF
• Look at some doctored photos
• Effects
• Exporting from AFX
• Photoshop timeline
• Optimizing and exporting

Theres a few things to keep in mind in
regards to web animation performance.

Recalculate styles

User agent, external, internal, and inline styles.

Layout

Lays out the geometry of each element to the page.

Paint

Redraws visual effects and altered pixel geometry.

Jank - A transition or animation that looks jittery or janky.
Yo son... that animation looks jank!

Composite

When everything is ready, the page is composited together.

This all happens very very fast...

A quick tour

... because you might already know about this stuff.

Usage

Only two properties are required for a CSS transition.

transition-property

transition-duration

The other two properties are optional
(transition-delay and transition-timing-function).

You could breakout everything:

.my-button {
  transition-property: transform; /* opacity, etc. */
  transition-duration: 1s; /* 200ms */
  transition-timing-function: ease; /* ease-in, ease-out, ease-in-out,
    linear, and cubic-bezier */
  transition-delay: 2s; /* 200ms */
}

or do shorthand:

.my-button {
  transition: transform 1s 2s;
}

timing-functions

Since transitions and animations must have a beginning and end,
cubic-bezier will give you the best unique motion.

.my-button {
  transition: transform 1s 2s cubic-bezier(0,.5,.5,1);
}

• Cubic Bezier
• Ceaser CSS Easing Animation Tool
• Easings

will-change

Give the browser a heads up by listing CSS
properties that will more than likely change.

.my-button {
  will-change: transform, opacity;
}

No more translateZ(0) or translate3d(0,0,0) hacks   ☺

• Everything You Need to Know About
  the CSS will-change Property

Performance

You'll want to stick to transitioning
transform and opacity as much as possible.

Altering anything else can be costly at a larger scale.

Transitioning layout properties creates
browser paint and composite issues.

CSS Exercise #1

Transitions

Transitions, Form misc

codepen.io/markgeyer/pen/yklLx/

Add transition properties to these form elements.

Usage

Transforms can seem complicated at first, so start
with altering translate, rotate, and scale.

With transforms, you can alter anything!

ANYTHING!

.my-box {
  width: 288px;
  height: 250px;
  color: #3d3d3d;
  background-color: white;
  border-radius: 5px;
  transform: translate(0,-30px) rotate(30deg) scale(.8);
}

But there's more... way more!

							.other-transforms {
  transform: none;

  transform: translate(12px, 50%);
  transform: translateX(2em);
  transform: translateY(3in);
  transform: translateZ(2px);
  transform: translate3d(12px, 50%, 3em);

  transform: scale(2, 0.5);
  transform: scaleX(2);
  transform: scaleY(0.5);
  transform: scaleZ(0.3);
  transform: scale3d(2.5, 1.2, 0.3);

  transform: rotate(0.5turn);
  transform: rotateX(10deg);
  transform: rotateY(10deg);
  transform: rotateZ(10deg);
  transform: rotate3d(1, 2.0, 3.0, 10deg);

  transform: skewX(30deg);
  transform: skewY(1.07rad);

  transform: matrix(1.0, 2.0, 3.0, 4.0, 5.0, 6.0);
  transform: matrix3d(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0,
             11.0, 12.0, 13.0, 14.0, 15.0, 16.0);

  transform: perspective(300px);
}

transform-origin

.my-box {
  transform-origin: 50% 50%; /* center */
}

It's just like animating the anchor point
layer property in After Effects.

Couple of things to setup for 3D:

.my-3d-box {
  transform-style: preserve-3d; /* 'flat' is the other option */
}

Then add perspective to either a parent element (multiple things in 3D):

.container {
  perspective: 1000px; /* anything between 300-1000px looks pretty good */
}

or on the element's transform (only thing in 3D):

.my-3d-box {
  transform: perspective(1000px);
}

.my-3d-box {
  width: 288px;
  height: 250px;
  color: #3d3d3d;
  background-color: white;
  border-radius: 8px;
  transform: perspective(1000px) translate(0,0) rotateY(30deg) rotateX(-30deg);
  transform-style: preserve-3d;
}

Also when doing 3D stuff, depending on the effect,
backface-visibility should be used.

.my-3d-object {
  backface-visibility: visible; /* hidden */
}

Performance

Anything within transforms are fair game
i.e. translate, rotate, scale, etc.

It's just a matter of browser support for the transform property.

CSS Exercise #2

Transforms

Transforms, Card flip

codepen.io/markgeyer/pen/cCBbq

Make this card flip when clicking it's button.

Usage

Only two properties are required for a CSS animation.

animation-name

animation-duration

All other properties are optional.

@keyframes is the timeline for an animation:

@keyframes my-ani {
  0% { /* Your CSS properties */ }
  50% { /* that change */ }
  100% { /* over time */ }
}

or

@keyframes my-ani {
  from { /* Your CSS properties */ }
  50% { /* that change */ }
  to { /* over time */ }
}

You could breakout everything:

.my-animation {
  animation-name: my-ani;
  animation-duration: 2s; /* 200ms */
  animation-delay: 1s; /* 100ms */
  animation-iteration-count: 2;
  animation-timing-function: ease; /* ease-in, ease-out, ease-in-out,
    linear, and cubic-bezier */
  animation-direction: normal; /* reverse, alternate, alternate-reverse */
  animation-fill-mode: none; /* forwards, backwards, both */
  animation-play-state: running; /* paused */
}

or do shorthand:

.my-animation {
  animation: my-ani 2s 1s 2 ease-in forwards;
}

Performance

Same things... you'll want to stick to
animating transforms and opacity.

Animating layout properties will
create layout, paint, and composite issues.

Tips

• Add negative delays (-.5s) to start further in the animation.
• Change z-index between keyframes to simulate layer switching.

Some popular JS libraries:

• GreenSock Animation Platform (GSAP)
• velocity.js
• famo.us
• Transit
• and yes, jQuery

The thing about jQuery tho...

Don't use it for animation!

• The $.animate() method causes severe paint issues.
• It can't avoid layout thrashing which creates jank.
• It's memory consumption freeze animations sometimes.
• It uses setInterval instead of requestAnimationFrame (rAF).

These are pretty good reasons.

For today, let use velocity.js because...

• it's familiar (if you've used jQuery before)
  and has great performance.
• it was built with the intention to replace
  jQuery's $.animate() method.
• well documented and meant for motion designers.

How does velocity.js work?

$('.my-dialog').velocity({ css properties }, { options });

Options: duration, easing, queue, begin, progress,
complete, loop, delay, display, and mobileHA

Docs: http://julian.com/research/velocity

UI pack usage: Faster UI animations with velocity.js

So... what should I use?

A CSS transition a CSS animation or a JS animation?

Use CSS transitions...

• for smaller mirco interactions.
• to toggle html element states.
• for pseudo elements (:hover, etc).

Use CSS animations...

• for single state animation.
• for an intricate animation sequence.
• if it's more comfortable for you.

Use JS animations...

• for multiple state animation.
• for access to requestAnimationFrame (rAF).
• for wider support (IE 8-9 and/or Android Browser 2.3)
