title: How do I remove the default border glow of a JavaFX button (when selected)?
body: <p>I'm trying to remove the border glow (please see screenshot below) that appears by default when a JavaFX button is selected:</p>
  
  <p><img src="https://i.stack.imgur.com/sc6qE.jpg" alt="The blue border is the default styling by JavaFX for when the the button is selected"></p>
  
  <p>I also want to do this using CSS, and not declaratively from within the main JavaFX script. However, I am having trouble figuring out what CSS property I need to use (er, set to 0?) in order to remove that border.</p>
