When to link jQuery Mobile css?

I notice that there are many CSS files that comes with jQuery Mobile. The main one jquery.mobile-1.4.5.min.css is obviously required.

But what about the rest? When do we need to include and link them? Do we need to include these files in the packaging for a mobile app or web site?

  1. jquery.mobile.external-png-1.4.5.min.css
  2. jquery.mobile.icons-1.4.5.min.css
  3. jquery.mobile.inline-png-1.4.5.min.css
  4. jquery.mobile.inline-svg-1.4.5.min.css
  5. jquery.mobile.structure-1.4.5.min.css
  6. jquery.mobile.theme-1.4.5.min.css
