title: React-Spring - Change Transition Animation Speed
body: <p>I'm trying to change the speed of the default fade-in and fade-out transition, but the documentation does not seem to mention how to do so:</p>
  <pre><code>&lt;Transition
    items={show}
    from={{ opacity: 0 }}
    enter={{ opacity: 1 }}
    leave={{ opacity: 0 }}&gt;
    {show =&gt; show &amp;&amp; (props =&gt; &lt;div style={props}&gt;✌️&lt;/div&gt;)}
  &lt;/Transition&gt;
  </code></pre>
  <p><strong>Given this code, how would I make the fade in / out animation faster or slower?</strong></p>
  <p>I tried doing this (below), but it ended up breaking down the transition entirely. The animation no longer worked:</p>
  <pre><code>from={{ opacity: 1, transitionDelay: &quot;5000ms&quot; }}
  enter={{ opacity: 1, transitionDelay: &quot;5000ms&quot; }}
  leave={{ opacity: 0, transitionDelay: &quot;5000ms&quot; }}
  </code></pre>
  <p>Any ideas?</p>
