    Following steps are required for showing a popup on mousehover on a link

    Step1: Attach the javascript file from http://code.jquery.com/jquery-1.6.3.min.js

    Step2: Write the following internal stylesheet under the head section of an aspx page

    .tooltip {
    width: 25%;
    padding: 5px;
    background-color: white;
    border: 3px solid rgb(195,151,51);
    border-radius : 5px;
    }
    .trigger {
    border-bottom: 1px dashed white;
    cursor : help;
    }
    .trigger:hover {
    color: rgb(255,0,0);
    }
    

    Step3: Write following script under head tag of an aspx page

    script type="text/javascript">
        $(document).ready(function () {
            $('.trigger').mouseover(function () {
                var ttLeft,
     ttRight,
     $this = $(this),
     $tip = $($this.attr('data-tooltip')),
     triggerPos = $this.offset(),
     triggerH = $this.outerHeight(),
     triggerW = $this.outerWidth(),
     tipW = $tip.outerWidth(),
     tipH = $tip.outerHeight(),
     screenW = $(window).width(),
     scrollTop = $(document).scrollTop();
                if (triggerPos.top - tipH - scrollTop > 0) {
                    ttTop = triggerPos.top - tipH - 10;
                } else {
                    ttTop = triggerPos.top + triggerH + 10;
                }
                var overFlowRight = (triggerPos.left + tipW) - screenW;
                if (overFlowRight > 0) {
                    ttLeft = triggerPos.left - overFlowRight - 10;
                } else {
                    ttLeft = triggerPos.left;
                }
                $tip.css({
                    left: ttLeft,
                    top: ttTop,
                    position: 'absolute'
                }).fadeIn(200);
            }); // end mouseover
            $('.trigger').mouseout(function () {
                $('.tooltip').fadeOut(200);
            }); // end mouseout
        });                //end ready
    
    

    Step 4: To test the script is working or not create a link under the body tag
