HTML Code

<a href="#" onMouseOut="linkTimer()" onMouseOver="showTipBox('Delete','imgDel')"><font class="font" color="#CC6600" face="Arial, Helvetica, sans-serif" size="2">Tip Box</font></a> <img src="/images/shim.gif" width="5" height="5" border="0" name="imgDel"> <div id=Delete style="position: absolute; width: 228px; height: 33px; z-index: 1; visibility: hidden"> <table border="0" cellspacing="0" cellpadding="0"> <tr> <td bgcolor="#990000"> <table border=0 cellpadding="4" cellspacing="1"><tr> <td bgcolor="#FFFFFF"><img src="/images/shim.gif" width="2" height="2" border="0"><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">This is a text link tip box : </font> <font face="Arial, Helvetica, sans-serif" size="2">This<br> function should be used for ..... ....... ........ </font></td> </tr> </table></td> </tr> </table> </div>

Instructions

Make a transparent gif called shim under your images folder as 'div' tag layers need an image to be present to work in Netscape plus we need it as a place holder (usually following the link) to show where the tip box should appear. If you are trying to use multiple tip boxes then you need to change the name of the respective div layer id field and also change the reference to it in the link onMouseOver event for the respective boxes. Also give the image place holder (here the shim image named imgDel) a new name property for each tip box and change the reference to it in the link onMouseOver event for the respective boxes.
