Curious about TG’s popup tool tip info? This is how we do it. This is a JS code from one of our favorite sites Dynamic Drive. Of course we have edited to better suit our look and needs. Here is the breakdown.
Put this in the <head> section or in your css file
<style type=
“text/css”>
#dhtmltooltip{
position: absolute;
width: 150px;
border: 2px solid black;
padding: 2px;
background-color: lightyellow;
visibility: hidden;
z-index: 100;
/*Remove below line to remove shadow. Below line should always appear last within this CSS*/
filter: progid:DXImageTransform.Microsoft.Shadow(color=gray,direction=135);
}
</style>;
Now for the Javascript and related coding. Place this somewhere in the body outside of any relative or absolute tags.
<div id=“dhtmltooltip”></div>
<script type=
“text/javascript”>

var offsetxpoint=-60 //Customize x offset of tooltip

Now just edit your link with the following information.
onMouseover="ddrivetip(’JavaScriptKit.com JavaScript tutorials’,'yellow’, 300)";
onMouseout="hideddrivetip()"
This is the breakdown of how the code works
ddrivetip(’TEXT TO DISPLAY’, ‘OPTIONAL BACKGROUND COLOR’, OPTIONAL TIP WIDTH)
Here are some examples of using the code in the links
<a href=“http://www.yahoo.com” onMouseover=“ddrivetip(’Visit Yahoo.com’)”;
onMouseout=“hideddrivetip()”>Search Engine
</a>
<DIV onMouseover=“ddrivetip(’This DIV has a tip!’, ‘#EFEFEF’)”;
onMouseout=“hideddrivetip()”>Some text here. Some text here.</div>
<a href=“http://yahoo.com” onMouseover=“ddrivetip(’Yahoo\’s Site’, ‘yellow’, 250)”;
onMouseout=“hideddrivetip()”>Yahoo</a>
This is a very helpful and attractive addon for your site. Be sure to leave in the credit for dynamic drive and check out the actual full page devoted to the addon HERE.
