title: Props conditional rendering using styled-components
body: <p>I am using styled-components library inside a React application and I have this block for example:</p>
  
  <pre><code>const Wrapper = styled.div`
    background: red;
  `;
  </code></pre>
  
  <p>I need to add some other style if a prop has a set value, something like:</p>
  
  <pre><code>const Wrapper = styled.div`
    background: red;
    color: white; // color should be added only if this.props.myProps == 'ok'
  `;
  </code></pre>
  
  <p>What's the best way to do this?</p>
