title: how could I center a small banner on my header using div tags
body: <p>I'm unable to center a small banner add on the header of my blog. I want it on the center and closer to the button of the header. Probably can be achieved with some style properties, but I can't find it. Here's how it looks now
  <a href="http://pctechtips.org" rel="nofollow">pctechtips.org</a></p>
  
  <pre><code>&lt;div id="header_add" style="background-color:#000000;height:70px;width:500px;float:center;align:center;"&gt;
  &lt;a style="color:yellow" href="http://pctechtips.org/contact/"&gt;&lt;small&gt;PCtechtips.org&lt;/small&gt;&lt;/a&gt;
  &lt;h2 style="color:blue;text-align:center;top-padding:0"&gt;Advertise Here!&lt;/h2&gt;
  &lt;/div&gt;
  </code></pre>
