title: Create styled component based on other component with props
body: <p>Adding a style to <code>P</code> works nicely:</p>
  
  <pre><code>const Quotation = styled(P)`
      &amp;::before, &amp;::after {
          content: '"';
      }
  `;
  </code></pre>
  
  <p>But what I want to do is add a style to <code>P</code> with the prop <code>italic=true</code> passed to it. Something like:</p>
  
  <pre><code>const Quotation = styled(P italic=true)`
      &amp;::before, &amp;::after {
          content: '"';
      }
  `;
  </code></pre>
  
  <p>How can I do that?</p>
