<p>The <code>animation</code> property is specified as one or more single animations, separated by commas.</p>

<p>Each individual animation is specified as:</p>

<ul>
 <li>zero or one occurrences of the following values:
  <ul>
   <li>{{cssxref("&lt;single-transition-timing-function&gt;")}}</li>
   <li>{{cssxref("animation", "&lt;single-animation-iteration-count&gt;", "#&lt;single-animation-iteration-count&gt;")}}</li>
   <li>{{cssxref("animation", "&lt;single-animation-direction&gt;", "#&lt;single-animation-direction&gt;")}}</li>
   <li>{{cssxref("animation", "&lt;single-animation-fill-mode&gt;", "#&lt;single-animation-fill-mode&gt;")}}</li>
   <li>{{cssxref("animation", "&lt;single-animation-play-state&gt;", "#&lt;single-animation-play-state&gt;")}}</li>
  </ul>
 </li>
 <li>an optional name for the animation, which may be <code>none</code>, a {{cssxref("&lt;custom-ident&gt;")}}, or a {{cssxref("&lt;string&gt;")}}</li>
 <li>zero, one, or two {{cssxref("&lt;time&gt;")}} values</li>
</ul>

<p>The order of values within each animation definition is important: the first value that can be parsed as a {{cssxref("&lt;time&gt;")}} is assigned to the {{cssxref("animation-duration")}}, and the second one is assigned to {{cssxref("animation-delay")}}.</p>

<p>The order within each animation definition is also important for distinguishing {{cssxref("animation-name")}} values from other keywords. When parsed, keywords that are valid for properties other than {{cssxref("animation-name")}}, and whose values were not found earlier in the shorthand, must be accepted for those properties rather than for {{cssxref("animation-name")}}. Furthermore, when serialized, default values of other properties must be output in at least the cases necessary to distinguish an {{cssxref("animation-name")}} that could be a value of another property, and may be output in additional cases.</p>

<h2 id="접근성_고려사항">접근성 고려사항</h2>

<p>Blinking and flashing animation can be problematic for people with cognitive concerns such as Attention Deficit Hyperactivity Disorder (ADHD). Additionally, certain kinds of motion can be a trigger for Vestibular disorders, epilepsy, and migraine and Scotopic sensitivity.</p>

<p>Consider providing a mechanism for pausing or disabling animation, as well as using the <a href="/en-US/docs/Web/CSS/@media/prefers-reduced-motion">Reduced Motion Media Query</a> to create a complimentary experience for users who have expressed a preference for no animated experiences.</p>

<ul>
 <li>Gecko has a bug whereby when you animate an offscreen element onscreen but specify a delay, Gecko does not repaint on some platforms, e.g. Windows ({{bug(1383239)}}). This has been fixed in Firefox's new parallel CSS engine (also known as <a href="https://wiki.mozilla.org/Quantum">Quantum CSS</a> or <a href="https://wiki.mozilla.org/Quantum/Stylo">Stylo</a>, planned for release in Firefox 57).</li>
 <li>Another Gecko bug means that {{htmlelement("details")}} elements can't be made open by default using the <code>open</code> attribute if they have an animation active on them ({{bug(1382124)}}). Quantum CSS fixes this.</li>
 <li>A further bug means that animations using em units are not affected by changes to the {{cssxref("font-size")}} on the animated element's parent, whereas they should be ({{bug(1254424)}}). Quantum CSS fixes this.</li>
