Jquery creates a layer that displays the title and content and moves with the mouse

 
<script src="Core/Public/js/jquery.js" type="text/javascript"></script> //The introduction of the Jquery
<style type="text/css"> //Write the style of the div you created
#tooltip 
{ 
position: absolute; 
border: 1px #solid #333; 
background: #f7f5d1; 
padding: 1px; 
color: #333; 
display: none; 
} 
</style> 
<script type="text/javascript"> //Writing JS code
$(function () { 
var x = 10; 
var y = 10; 
$("a.tooltip").mouseover(function (e) { //When the mouse pointer moves over an element
this.myTitle = this.title; 
this.title = ""; 
var tooltip = "<div id='tooltip'>" + this.myTitle + "</div>";
