Laggy CSS animation
<p>I'm trying to size up some container on my site using CSS3-animation.</p>

<p>This is my Container:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>.new-place-wrapper {
  background: #004682;
  display: inline-block;
  margin-top: 70px;
  animation-name: newplace;
  animation-duration: 1s;
  animation-fill-mode: forwards;
  animation-delay: 3s;
  animation-timing-function: linear;
  max-height: 0px;
  padding: 0px 20px;
  overflow: hidden;
  position: relative;
  z-index: 8888;
}

@keyframes newplace {
  0% {
    max-height: 0px;
    padding: 0px 20px;
  }
  100% {
    max-height: 9999px;
    padding: 20px 20px;
  }
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="new-place-wrapper" data-equalizer&gt;
  &lt;div class="new-place-close"&gt;&lt;i class="fa fa-times"&gt;&lt;/i&gt;&lt;/div&gt;
  &lt;div class="inner-place-left" data-equalizer-watch&gt;
    &lt;span&gt;Wir sind umgezogen!&lt;/span&gt;
    Ab sofort finden Sie uns hier:
    &lt;address&gt;
      &lt;strong&gt;Company&lt;/strong&gt;&lt;br&gt;
      STREET 123&lt;br&gt;
      CITY&lt;br&gt;&lt;br&gt;
      PHONE
    &lt;/address&gt;
  &lt;/div&gt;
  &lt;div class="inner-place-right" data-equalizer-watch&gt;
    &lt;a class="button radius" href="#"&gt;VCF-Karte&lt;/a&gt;
  &lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>

<p>Basically the animation works quite fine but there is a strange lagging at the beginning. Firstly the container gets higher juddering. After a moment the animation goes on very smooth.</p>
