title: Customise Tumblr's *new* Like Button iFrame {LikeButton}
body: <p>The new code from tumblr <code>{LikeButton}</code> comes with a very few options: color and size.</p>
  
  <p>It injects an iFrame, which handles the "Like" functionality and provides SVG graphics. </p>
  
  <p>However because of the iframe and cross site scripting policies, it is no longer possible to alter it with css nor to edit its contents.</p>
  
  <p>How can I modify, or insert new code, to use my own Like button sprites or svgs?</p>
