title: PHP how to add link to resources use klein.php
body: <p>I'm writing a training app using basic PHP and routing klain.php I have a problem. How to connect to own css/js here. How to set the path to CSS and js, because routing klain.php blocks all park paths.</p>
  <p>I use this but not work:</p>
  <pre><code>$klein-&gt;respond('/css/main.css', function ($request, $response, $service) {
      $response-&gt;file('/css/main.css');
  });
  </code></pre>
