title: jQuery UI Spinner - Remove blue border
body: <p>I have the following jQuery spinner:</p>
  
  <p><img src="https://i.stack.imgur.com/4SDiy.png" alt="enter image description here"></p>
  
  <p>I'd like to remove the blue border that appears when the input control has the focus but, after examining the jquery-ui.css file, I can't find the CSS that controls this.</p>
