title: How to Position an Element Absolute from Center - CSS
body: <p>For a client, I need to put together an absolute div to the left of the body containing an advertisement.  The only way I have figured out how to do this thus far is to create an absolute div.  The issue here is that in the absolute positioned div, there is a black space (which is the end of the body) and I need to have this "gutter space" ad hugging the page.  </p>
  
  <p>To account for this, the best method is to position this a set number of pixels away from the center of the page.  I thought I could do this by the following code:  </p>
  
  <pre><code>position: absolute;
  left:50%;
  margin-right:500px;
  </code></pre>
  
  <p>However, this just keeps the div in the center of the page.  Is it possible to position an absolute div from the center of a page?  </p>
