title: What is the <i> tag use for?
body: <p>Well I know it is meant to italicize text, but I have been using firebug on Facebook and I cannot help but realize how much they use the <code>&lt;i&gt;</code> tags in their layout. </p>
  
  <p><img src="https://i.stack.imgur.com/137ca.png" alt="i tag in Facebook photo layout"></p>
  
  <p>For example, for the photo thumbnail gallery, Facebook uses the <code>&lt;i&gt;</code> tag inside a div and places a background image style for the  tag in the photo gallery. Are there more tricks/tips/uses to the  tag ?</p>
