title: Wider off canvas menu too wide to close on mobile
body: <p>When changing the variable <code>$off-canvas-width</code> to a larger scale in <code>settings.scss</code> the off canvas menu successfully get's wider. But now the off canvas menu is too wide for mobile so the hamburger icon isn't available anymore. So it isn't possible to collapse close the menu again.</p>
  
  <p>Is there a way to add a manual close button in the mobile menu which is only visible on mobile?</p>
  
  <p>-or-</p>
  
  <p>Is there a way to change the width of the sidebar per media query?</p>
