title: Jquery selector: targeting an element with two class prefixes
body: <p>I have some elements that contain two similar classes like "col-md-3 col-md-6" on the same element and I want to identify them with a jQuery selector.</p>
  
  <p>example:</p>
  
  <pre><code>&lt;div class="col-md-3 col-md-6"&gt;&lt;/div
  </code></pre>
  
  <p>how can I select only elements that contain these two classes? </p>
  
  <p>I have tried something like :</p>
  
  <pre><code>$("[class*='col-md-'][class*='col-md-']").css("background", "#07BCCD")
  </code></pre>
  
  <p>but is targeting all elements with one or two class prefix "<code>col-md-"</code></p>
