@ducaaleyare not sure why you opened this as a showcase discussion. This looks like an issue to me. In future please follow the discussion categories correctly or open an issue, otherwise we may just close them.

As @toxinliquid suggested, you have typed two : between flux and sidebar.collapse, when there should be only one. Try this and if it doesn't fix it, please open an issue.
