title: Why would the background-image property cause a warning in Chrome?
body: <p>I'm using jQuery's <code>.css()</code> method to set the background image of a <code>div</code>. The HTML in its final state is thus:</p>
  
  <p><code>&lt;div id="front-page-bg" style="background-image: url(http://peterfcarlson.com/wp-content/uploads/2011/09/ert-011.jpg); display: block; "&gt;&lt;/div&gt;</code></p>
  
  <p><em>It works fine</em>, however, I'm getting an error/warning in Chrome, where the <code>background-image</code> property is struck through as though it's being ignored due to bad input, even though it is obviously being applied. Why would this be? Is it a problem with Chrome, or on my end?</p>

  <p>I've tested the page in FF and IE, where it also seems to work without any errors or similar warnings. Any ideas about why this might be happening, and perhaps more importantly, should I ignore it, since the page seems to be working?</p>
