title: CSS' calc() in styled-components
body: <p>Trying this:</p>
  
  <pre><code>const styledDiv = styled.div`
    ${props =&gt; props.takeViewportHeight &amp;&amp; `min-height: calc(100vh-16px);`}
  `
  </code></pre>
  
  <p>It's not working. Am I missing something about calc in styled components?</p>
