A Merry Christmas and happy holidays to all of you!!
After searching I finally found a script to make it snow on your website.I am sharing the code with all of you. Following is the graphic to display how it looks. It is pretty good!
and type the folowing code in its content. You may leave the title blank.
snowStorm.flakesMaxActive = 890;
snowStick = 1;
snowStorm.followMouse = false;
snowStorm.snowStick = false;
snowStorm.animationInterval = 33;
snowStorm.flakesMax = 250;
snowStorm.vMaxX = 5;
snowStorm.vMaxY = 5;
Otherwise, paste the above code in between <body> and </body> tags. I hope the code will work fine, Happy Snowing!
