title: "Pay With A Tweet" button on top of tumblr posts?
body: <p>I'm trying to add my iframe "paywithatweet" button on top of my tumblr theme.
  I want the button to be at the same position all the time, and not affected by scrolling through posts.</p>
  
  <pre><code>&lt;div style="position:absolute; left:77; top:77; width:377; height:377; clip:rect(0,381,381,0); background:#FFF;"&gt;
    &lt;iframe src="paywithatweet.com/…; class="spaced-right" name="paytweet_button" scrolling="no" frameborder="no" height="48px" width="292px"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Apologies if that's a stupid question as it sounds easy...</p>
  
  <p>Thank you very much in advance!</p>
