title: Toggle class don't remove class
body: <p>I'm trying to make an <code>article</code> add a class while a menu is open.
  So, when the button is clicked, this will show the menu and also certain item (the <code>article</code>) should get the class <code>padded</code>, and when we press the button again, the class <code>padded</code> must be removed.</p>
  
  <p>Now, it's adding the class, but not removing it when the button is clicked again</p>
