Hide / Chat Box (Ver 2)

Today it wandering on Google to find the code hide / show pretty good chat box.

 This code is more smooth effects are quite impressive but which is not in use Jquery or Mootools, so can be assured about the speed issue. I have added the button design.

 Here is the code of the Chat Box V2 (insert the card </body>)

<style type='text/css'>
.gb_fixed{position:fixed;top:30px;right:0px;z-index:+10;}
* html .gb_fixed {position:relative;}
#hidden_gb2 {
display:none;
border:4px solid #bf3989;
-webkit-border-radius:5px;
-moz-border-radius:5px;
border-radius:5px;
background:#fff;
padding:0 3px 3px 3px;
}
</style>
<div class='gb_fixed'>
<table cellpadding='0' cellspacing='0' id='hidden_gb2'>
<tr><td><div><a href='javascript:void(0)' onclick='gb_showHideGB()'><b><center>[ Đóng Chat Box ]</center></b></a></div>

Code Shoutbox/Cbox

</td></tr></table></div>
<script type='text/javascript'>
//<![CDATA[
var gb_obj = document.getElementById("hidden_gb2");
var gb_finish = false;

function gb_setInitBehaviour(){
gb_obj.isHidden = true;
gb_setOpacity(gb_obj, "0.01");
}
function gb_setOpacity(obj, opacity){
opacity = opacity.substr(0, 4);
obj.style.opacity = opacity;
obj.style.filter = "alpha(opacity="+(Math.floor(parseFloat(opacity)*100)).toString()+")";
//writex(opacity);
}
function gb_showGB(){
gb_obj.style.display = "block";
gb_changeOpacityTo(1, "");
gb_obj.isHidden = false;
}
function gb_hideGB(){
gb_changeOpacityTo(0.01, "gb_obj.style.display = \"none\"");
gb_obj.isHidden = true;
}
function gb_changeOpacityTo(fin, funcStr){
var init = parseFloat(gb_obj.style.opacity.substr(0, 4));
var d = init <= 0.2 ? 0.04 : init <= 0.6 ? 0.08 : 0.20;
var m = fin>init ? 1 : -1;
var opacity = init + d * m;
if((fin-opacity)*(fin-init)<0){opacity = fin;}
gb_setOpacity(gb_obj, opacity.toString());
if(opacity != fin){setTimeout("gb_changeOpacityTo("+fin.toString()+", '"+funcStr+"')", 50);}
else{eval(funcStr);}
}
function gb_showHideGB(){
if(gb_obj.isHidden){gb_showGB();}
else{gb_hideGB();}
}
function writex(str){
document.getElementById("wx").innerHTML += str + " ";
}
gb_setInitBehaviour();
