Reflection Images adalah membuat efek bayangan pada images anda,Saya selalu tertarik dengan efek gambar berbayang atau disebut efek image reflection. Gambar yang ditampilkan dengan efek bayangan akan membuat images anda semakin indah.bagaimana caranya???ok saya akan mencoba membuatnya dengan menggunakan javascript sbb:
1.letakan script dibawah ini pada bagian <head> web anda
<script type="text/javascript" src="reflection.js"></script>
2.Letakan script dibawah ini pada bagian <body>
<img src="gambar_anda.jpg" width="200" height="150" class="reflect">
3.Buat script reflection pada notepad dan beri nama reflection.js seperti dibawah ini scriptnya :
reflection.js
/* This script and many more are available free online at

/* From prototype.js */
if (!document.myGetElementsByClassName) {
document.myGetElementsByClassName = function(className) {
var children = document.getElementsByTagName('*') || document.all;
var elements = new Array();
for (var i = 0; i < children.length; i++) {
var child = children[i];
var classNames = child.className.split(' ');
for (var j = 0; j < classNames.length; j++) {
if (classNames[j] == className) {
elements.push(child);
break;
}
}
}
return elements;

}
// Multiple onload function created by: Simon Willison
// http://simonwillison.net/2004/May/26/addLoadEvent/
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
addReflections();
// add other functions here
});
Hasil nya dapat anda lihat disini
Selamat mencoba....!!!
