title: Adding a class or style to a disabled button
body: <p>I am disabling a button until atleast one checkbox has been selected like so:</p>
  
  <pre><code>var checkboxes = $("input[type='checkbox']"),
      submitButt = $("input[type='button']");
  
  checkboxes.click(function() {
      submitButt.attr("disabled", !checkboxes.is(":checked"));
  });
  </code></pre>
  
  <p>My buttons initial state is disabled but I need it to be like faded out or opacity added to it, im not sure what the best approach would be either do it with adding a class or just adding CSS? im not really sure?</p>
