/* ***********************
Call the 2 functions below with a window.onload function, and the styles of your rows will alternate automatically:

window.onload = function(){
	if(document.getElementById) 
	setAltTableRows('myTableClass');
	setAltDivRows('myDivClass');
}

Use the setAltTableRows if you have tables, setAltDivRows for divs, and everything will work nice nice.

	Love,
