title: jQuery add variable
body: <p>I found a script <a href="https://stackoverflow.com/a/10400225">here</a> that equalizes the height of divs in a row (bootstrap). How do you add 20 for instance to the new height it calculates?</p>
  
  <p>Here is the script and a jsFiddle:

  <pre><code>$('.well, .alert').height(function () {
      var h = _.max($(this).closest('.row').find('.well, .alert'), function (elem, index, list) {
          return $(elem).height();
      });
      return $(h).height();
  });
  </code></pre>
