Tutorial cara buat background warna bergerak yang menarik

Tutorial cara buat efek warna backgroud menarik by Blogger Blog Tutorial

Efek ni memang menarik tertarik dan memang da bomb...tapi oleh sebab aku ada setkan kaler pada main wrapper aku efek ni x berapa menyerlah tapi tetap daa bomb

live demo anda boleh tengok sendiri dalam entri ni...apa macam da bomb?

Cara pasang widget ni pun senang..mula2 pergi ke desbot--desaign--ada gadjet--html / javascript...kemudian copy dan paste code di bawah lepas tu save setel...

<script type="text/javascript">
// <![CDATA[
var border=50; // how wide is each border
var effects=3; // how many of the effect are on the page
var speed=50; // how fast is the animation (lower is faster)
var colours=new Array("#9cf", "#c9f", "#fc9", "#f9c", "#cf9", "#9fc", "#6ff", "#f6f", "#ff6");
// above line lists colours for the groovy effect (can be as long or short as you like)
