title: jQuery conflict with other library (MooTools)
body: <p>I'm having trouble implementing a small javascript that uses jQuery. The code is</p>
  
  <pre><code>$(document).ready(function () {
       $("span.question").hover(function () {
           $(this).append('&lt;div class="tooltip"&gt;&lt;p&gt;This is a tooltip. It is typically used to explain something to a user without taking up space on the page.&lt;/p&gt;&lt;/div&gt;');
       }, function () {
           $("div.tooltip").remove();
       });
   });
  </code></pre>
  
  <p>I've seen similar posts where the problem was said to be caused by a mootools javascript conflict. So I replaced each instance of '$' with 'jQuery' but the script still does nothing and no errors are shown in the firebug console. Would someone be able to indicate to me what the problem is?
  Thanks.</p>
