title: How to use theme colors in ant design?
body: <p>I want to use the primary color from the ant design theme. I believe the less tag is: <code>@primary-color</code> . How do I use this value for a custom div that I want the border color to match? Also this is with an app made by create-react-app.</p>
  
  <p>I want to be able to do something like:</p>
  
  <pre><code>border: '2px solid #fff' // Instead of white, it uses the theme's primary color
  </code></pre>
