Jquery not fully working in Cloud9


I’m trying to code with jquery but it doesn’t seem to be fully functional in the preview. I am able to do a test alert and confirm that jquery is loaded, however, certain jquery functions like .focus and .animate are not working. I have a project that was coded and working properly on codepen that I’ve put into Cloud9 and it isn’t working. Here are the 2 url links to compare: https://codepen.io/xfroggy/pen/dNXarJ and https://ide.c9.io/xfroggy/wikipedia-viewer#openfile-README.md?debug=2. The problem is that with the Cloud9 version, the input box does not animate open on focus as it should. Does anyone have a suggestion for this?
