title: CSS Emotion Library - Getting css props error when using css prop
body: <p>This is my code</p>
  <pre><code>import { css, jsx } from '@emotion/core'
         
  return (
         &lt;&gt;
         &lt;img css={css`height: 200px; height: 200px;`} fluid={image.sharp.fluid} /&gt;
         &lt;List&gt;
             &lt;li&gt;Our Clients&lt;/li&gt;
             &lt;li&gt;What We Do&lt;/li&gt;
             &lt;li&gt;Contact&lt;/li&gt;
         &lt;/List&gt;
         &lt;/&gt;
     )
  </code></pre>
  <p>This is the error I'm getting</p>
  <blockquote>
  <p>You have tried to stringify object returned from <code>css</code> function. It
  isn't supposed to be used directly (e.g. as value of the <code>className</code>
  prop), but rather handed to emotion so it can handle it (e.g. as value
  of <code>css</code> prop).</p>

  <p>This error seems to be telling me that I need to do what I am already doing? Or am I missing something here.</p>
