title: Globally toggle css classes?
body: <p>I have some CSS that outlines every div in red.  I use it for debugging to see how elements are aligning.</p>
  
  <p>I have a button that currently toggles a bunch of debugging features on my app.  I'd like to incorporate the toggling of my red outlines as well.</p>
  
  <p>How would I go about toggling these classes considering I'm using angular and the angular cli?  I'd like to avoid dynamically loading and unload the style sheet if at all possible.</p>
