title: How to ignore multiple classes using the :not selector?
body: <p>I have this selector below where it ignores any <code>li</code> with the class <code>show-all-boxes</code>     </p>
  
  <pre><code>$('.boxes li:not([class="show-all-boxes"]) input:checkbox')
  </code></pre>
  
  <p>What is the best way of adding multiple classes to be ignored by the selector? An example of this that I thought would work but it doesn't is:</p>
  
  <pre><code>$('.boxes li:not([class="show-all-boxes, show-all-circles, show-all-triangles"]) input:checkbox')
  </code></pre>
