Html5 chat and Joomla Full screen (update)

To run the Joomla plugin in full screen mode, you need to edit the plugin located in

/plugins/content/html5chat/html5chat.php

and change the content of $script by

    $script = "<style>
    #iframeChat {
        height: 100%;
        width: 100%;
        border: none;
        position: absolute;
        left: 0px;
        top: 0px;
        z-index: 9999;
    }
    </style>";

    $script.= "<script src='https://html5-chat.com/joomla/$webmasterid/$encoded'></script>";
    $script.="<script>
        jQuery('#iframeChat').detach().appendTo('body');
    </script>";

You chat should then appear in FULL screen above all elements.
