title: Caching/Optimising Fonts with Service Worker
body: <p>I have a basic Service worker script that caches my fonts.css file.
  The service worker are getting registered on page load in my index.html file but I am also loading the fonts.css file directly in my index.html.
  <br><br>
  Is it right that the service worker file will intercept the request and responds with the cached fonts.css file?
  Or does caching the fonts.css file has no effect as the Browser still has to request the listed fonts?<br></p>
  
  <p>I believe the latter is whats going on but it would be great if someone could clear thing up for me. Would be the best approach to cache the whole fonts folder not only the fonts.css file? </p>
