The flags of all countries in the world in one sprite

Include 1 css file and have all the worlds' flags on your site. Tell everyone who uses a lot of country flags to use this link, so it will be in everyone's cache!

Example usage:

In the head of your html file:

<link
    rel="stylesheet"
    type="text/css"
    href="//github.com/downloads/lafeber/world-flags-sprite/flags32.css"
/>

In the body of your html file:

<ul class="f32">
  <li class="flag ar">Argentina</li>
  <li class="flag au">Australia</li>
  <li class="flag at">Austria</li>
  ...
</ul>

Or:

<ul class="f32">
  <li class="flag arg">Argentina</li>
  <li class="flag aus">Australia</li>
  <li class="flag aut">Austria</li>
  ...
</ul>

The countries corresponding to the codes can be found at: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 and https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3

If a previously visited site uses this same code, the file is already in the cache of the user and doesn't need to be downloaded again.
