Salsa's Tutobies Blog: Clickplosion Cursor Effect

Hello, aku lagi rajin ngepost tuto nih, soalnya mumpung lagi libur.

Tau gunanya tuto ini? Kalo kalian klik apapun, akan keluar kembang api gitu. Klik disini aja ya untuk live preview! Credit kodenya ke kak Ehza. Tapi kode warnanya aku ubah sendiri jadi pink doang, di blog kak Ehza kan warna warni xD

Pertama tama, copy dulu kode ini :

<script type="text/javascript">
// <![CDATA[
var sparks=75; // how many sparks per clicksplosion
var speed=33; // how fast - smaller is faster
var bangs=5; // how many can be launched simultaneously (note that using too many can slow the script down)
var colours=new Array('#ffc9d4');
// pink
