jQuery add variable
<p>I found a script <a href="http://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:
<a href="http://jsfiddle.net/MVP3C/" rel="nofollow">http://jsfiddle.net/MVP3C/</a></p>

<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>
