title: How to remove Angular ng-invalid while typing?
body: <p>The error effect (ng-invalid) shows as soon as you select a field. How can I stop this when:</p>
  
  <ol>
  <li>When I haven't typed anything yet</li>
  <li>When I'm still typing</li>
  </ol>
  
  <p>Solution to either one would be great.</p>
