Fullcalendar and CSS mouseover

[NomadicJosh]

I am using fullcalendar, and I am trying to position the mouseover.

 

The current css is:

    .nube { 
    position:absolute;
    left:0;
    top:0;
    z-index:-10000;
    border:1px solid #DCA;
    background:#fffAF0;
    padding:1em;
    display: none;

	max-width: 800px;
	min-width: 100px;
	
	line-height: 12px;

	direction: ltr;

	box-shadow: none;
    color: #111;
    font-size:.8em;
    }

Attached is a screenshot of the issue. Can anyone help me figure out what I need to change in the css above? Thanks.
