<h2>Why CSS? ❓</h2>
<h3>1. Simple, yet powerful.</h3>
<p>All the CSS ever written:
<pre><code class="language-css">
selector {
property: value;
}</code></pre>
<a target="_blank" rel="noopener noreferrer" href="http://csszengarden.com/">CSS Zen Garden</a> <br>
<a target="_blank" rel="noopener noreferrer" href="https://resilientwebdesign.com/chapter2/#amatterofstyle">Resilient Web Design</a>
</p>
<h3>2. Performance</h3>
<p>CSS Animations are offloaded to GPU, so keep things off the main thread (Web Animations API does mimic this). <a target="_blank" rel="noopener noreferrer" href="https://www.html5rocks.com/en/tutorials/speed/high-performance-animations/"><blockquote>"Modern browsers can animate four things really cheaply: <strong>position, scale, rotation and opacity</strong>."</blockquote></a>
</p>
<h3>3. Principle of Least Power</h3>

<h2>Q: Why Animate? 🕺</h2>
<h3>A: Better UX.</h3>
<ul>
<li>It's a communication aid.</li>
<li>Users expect it.</li>
<li>It builds your brand and your site's personality.</li>
</ul>

<h2>Easy, lazy animations</h2>
<p>Go from point A to point B using transitions & leverage browser's 🧠 to figure out the in-betweens. </p>
<p>Syntax:
<pre><code class="language-css"> transition: [property][duration][delay][easing] ... ;</code></pre> </p>
<p>We'll attach the change to <em>a change in the element's state.</em> Here's an example: </p>
<a href="#💅" class="example-link">Hover Me</a>
<pre><code class="language-css">
a.example-link { color: aquamarine; }
a.example-link:hover { color: orangered; }
</code></pre>
<p>Ease-y upgrade: customize the timing function using dev tools or a site like <a target="_blank" rel="noopener noreferrer" href="https://cubic-bezier.com">cubic-bezier.com</a> or <a href="https://easings.net/">easings.net</a></p>

<h2>Make it Hot with Pseudo Elements</h2>
<h3>Now we're cookin' with gas 🔥</h3>
<a href="#🔥" class="button glowy shiny">Hot Button 💣</a>
<p>Hey - don't put important content in a pseudo element! It's not real, it's pseudo.</p>
<p>Syntax ( two colons is modern :: ) </p>
<pre><code class="language-css">
.button:hover::before {targets before pseudo element on hover}
.item:hover .info {targets element with .info class when you hover on .item}
</code></pre>

<h2>Keyframes for Complex Animations 🗝</h2>
<a target="_blank" rel="noopener noreferrer" href="https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Animations/Using_CSS_animations">MDN Web Docs</a>
<pre>
<code class="language-css">
.animated {
animation-name: bounce; /* from your keyframes */
animation-duration: 4s; /* s or ms */
animation-iteration-count: 10; /* infinite is an option */
animation-direction: alternate; /* or normal */
animation-timing-function: ease-in-out; /* remember cubic-beziers? */
animation-fill-mode: forwards; /* or backwards, both, none */
animation-delay: 2s; /* or ms */
}
.animated {
animation: duration | timing-function | delay |
iteration-count | direction | fill-mode |
play-state | name;
}

<h2>A Few UI Animation Best Practices 🏆</h2>
<ol>
<li>Don't abuse your animation powers - only write animations that are necessary and useful to our users</li>
<li>Don't conflict with users expectations (e.g. a banking form that "bounces" will be distrusted)</li>
<li>"Performance and accessibility goals affect all aspects of our design work, and animation is no exception there." <a href="https://www.smashingmagazine.com/2019/02/animation-design-system/">Val Head for Smashing Magazine</a>
</li>
<ul>
<li>Avoid animating properties that will trigger layout or paints.</li>
<li>Make sure your animations aren't disturbing users with vestibular disorders or low motion preferences. <a href="https://web.dev/prefers-reduced-motion/">"Prefers reduced motion"</a> media query in Chrome 74</li>
