title: How do you change the background color of the electron browserWindow (e.g. with a button click)?
body: <p>I know how to change the background colors in the CSS, but there is still the slightest border in the electron window (frameless), and I want to change that to the same color as in my webpage.  </p>
  
  <p>The window is generated in the </p>
  
  <p><code>app.on('ready', function() {});</code></p>
  
  <p>And I don't know how to call that again, and change the attribute for the backgroundColor. </p>
  
  <p>Any help is appreciated.</p>
