title: jQuery UI Slider Not Appearing
body: <p>I thought the basic syntax for a slider was:</p>
  
  <pre><code>&lt;div id="slider"&gt;&lt;/div&gt;
  
  $("#slider").slider()
  </code></pre>
  
  <p>But that doesn't make a visible slider.  Inspecting the <code>div</code> element, I see that some stylings were applied, but the slider isn't visible.</p>
  
  <p>Here's a fiddle: <a href="http://jsfiddle.net/yqNcn/" rel="noreferrer">http://jsfiddle.net/yqNcn/</a></p>
