I found this one on my website.
but I would make it mine ... just to help a little, a small example.
<style>
.item {
position: relative;
width: 100px;
height: 40px;
top: 200px;
left: 400px;
background: #CCC;
}
.item .tooltip {
position: fixed;
width: 80px;
height: 30px;
background: #06F;
z-index: 10;
display: none;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
$(".item").mousemove(function(e) {
$('.tooltip').css('left', e.pageX + 10).css('top', e.pageY + 10).css('display', 'block');
});
$(".item").mouseout(function() {
$('.tooltip').css('display', 'none');
});
});
</script>
<div class="item">
<p>This is my item</p>
<div class="tooltip">Tooltip</div>
</div>
