title: React Styled Components conditional ternary operator
body: <p>I'm trying to conditionally style a box with three different colors depending on the value of my test.</p>
  
  <pre><code>if test = A or B, it needs to be yellow
  if test = C, it needs to be green,
  if test = anything else, it needs to be blue.
  </code></pre>
  
  <p>I would rather write a switch or if/else, but I don't know if its possible to not use a ternary operator with Styled Components.</p>
