title: How do I select an element in the DOM using an attribute name that contains a colon?
body: <p>I am using the library Chartist, and it is adding an attribute to some of the elements of the DOM named <code>ct:value</code>. For example:</p>
  
  <pre><code>&lt;line y1="122.6875" y2="122.6875" x1="242.33333333333334" x2="262.06666666666666" class="ct-bar" ct:value="1"&gt;&lt;/line&gt;
  </code></pre>
  
  <p>I want to do some selective styling depending on what the value of <code>ct:value</code> is.  How would I select that using a CSS selector?</p>
