3-State highlight menu effect
Description: This is a 3 state menu effect, applicable to any table. The table cell in question "hovers up" when the mouse moves over it, and depresses when down. A snap to install, your table links will never be the same in IE4+ and NS6!

Configuring the menu
The code of Step 2 illustrates what must be done to a standard table to have the effect applied to its cells. Firstly, have present the onMouse...code inside the <table> tag itself, as follows:
<table onMouseover="over_effect(event,'outset')" onMouseout="over_effect(event,'solid')" onMousedown="over_effect(event,'inset')" onMouseup="over_effect(event,'outset')" style="background-color:#F0F0F0">
Secondly and finally, for each of the table cells (<td>) that you wish the effect to be added to, add the class=... code inside it:
<td class="menulines">.......</a>
Viola!
