title: Can we use rems to style a component in react native
body: <p>I want to use <code>rem</code>s for styling as I normally do in other CSS projects. But I don't understand how to get this working. This doesn't seem to work at all.</p>
  <pre><code>const styles = StyleSheet.create({
    header: {
      fontSize: 3rem,
      fontWeight: 400
    }
  });
  </code></pre>
