title: Properly define icon for website
body: <p>Say I have an SVG with an icon I want to use for my website.</p>
  
  <ol>
  <li>What sizes and formats should I convert it into?</li>
  <li>How would my HTML look like?</li>
  </ol>
  
  <p>I know how to specify a simple 16x16 favicon, but my goal here is that the icon should work and look good for as many use-cases as possible. For example the favicon, bookmarks, iPhone touch icons, desktop icons, windows 8 pinned web sites, and so on.</p>
  
  <p>So, basically looking for an HTML example which covers as much as possible together what format and size the image files should be in.</p>
