DHTML - JavaScript Spider Highlighter for Text Links

DHTML - JavaScript Spider Highlighter for Text Links Code
Do you want a very special rollover effect that none of your visitors has seen before? Try our new spider highlighter script for text links! No images needed. Copy and paste installation. Easy configuration of colors and weight (thickness) of spider lines! IE5 or higher.

Test the script below:
Just move your mouse over this text link to see the highlight effect. The script even allows you to use different highlight colors on the very same web page as this text link and this text link are demonstrating.

Configuration:

Step 1: Open your web page. Paste the following code right below the <body> tag of your web page (on top of the content of your web page):

<STYLE>
v\:* {
 BEHAVIOR: url(#default#VML)
}
</STYLE>

Step 2: Put the red and blue code below into your text link tags:
<a href="http://www.anydomain.com/anyfile.html" onMouseOver="msover('blue')" onMouseOut="msout()">

Step 3: Configure your favorite highlight color for each text link by replacing the blue sample color above.

Step 4: Go to the top of the script and configure the default color and the weight of the 8 spider lines.
