Very helpful post, another very simple question regarding this this post, where do you put delay? I tried both place, didn't seem work for me.

hi guys, When I click dave btn and steve btn several times quickly, then the green and red boxes are not expanding the size they should. What do I do to fix this problem? And, how to disable either one while another one is in animation? Thanks a lot. http://codepen.io/7537247/pen/AqLEc
