I need to change the style of the "OK" Button in an alert box.

<head>
    <script type="text/javascript">
        function show_alert() {
            alert("Hello! I am an alert box!");
        }
    </script>
</head>
<body>
    <input type="button" onclick="show_alert()" value="Show alert box" />
</body>

You need to create your own alert box like this:

function jAlert(text, customokay){
	document.getElementById('jAlert_content').innerHTML = text;
    document.getElementById('jAlert_ok').innerHTML = customokay;
    document.body.style.backgroundColor = "gray";
    document.body.style.cursor="wait";
}



jAlert("Stop! Stop!", "<b>Okay!</b>");
#jAlert_table, #jAlert_th, #jAlert_td{
    border: 2px solid blue;
    background-color:lightblue;
    border-collapse: collapse;
    width=100px;
}

#jAlert_th, #jAlert_td{
    padding:5px;
    padding-right:10px;
    padding-left:10px;
}

#jAlert{
    /* Position fixed */
    position:fixed;
    /* Center it! */
    top: 50%;
    left: 50%;
    margin-top: -50px;
    margin-left: -100px;
}
<p>TEXT</p>
<div id="jAlRem">
    <div id="jAlert">
        <table id="jAlert_table">
            <tr id="jAlert_tr">
                <td id="jAlert_td">  <p id="jAlert_content"></p>  </td>
                <td id="jAlert_td">  <button id='jAlert_ok'  onclick="jAlertagree()"></button>  </td>
            </tr>
        </table>
    </div>
</div>





<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>
<p>TEXT</p>


<script>
function jAlertagree(){
    var parent = document.getElementById('jAlRem');
    var child = document.getElementById('jAlert');
    parent.removeChild(child);
    document.body.style.backgroundColor="white";
    document.body.style.cursor="default";
}
</script>

The js portion gets the element in the HTML to create the alert box, then deletes it after the user clicks ok.

You can call the alert using jAlert("Custom Text", "Ok!");

Not possible. If you want to customize the dialog's visual appearance, you need to use a JS-based solution like jQuery.UI dialog.

One option is to use altertify, this gives a nice looking alert box.

Simply include the required libraries from here, and use the following piece of code to display the alert box.

alertify.confirm("This is a confirm dialog.",
  function(){
    alertify.success('Ok');
  },
  function(){
    alertify.error('Cancel');
  });

The output will look like this. To see it in action here is the demo

Option1. you can use AlertifyJS , this is good for alert

enter image description here

enter image description here

Option2. you start up or just join a project based on webapplications, the design of interface is maybe good. Otherwise this should be changed. In order to Web 2.0 applications you will work with dynamic contents, many effects and other stuff. All these things are fine, but no one thought about to style up the JavaScript alert and confirm boxes. Here is the they way

create simple js file name jsConfirmStyle.js. Here is simple js code

ie5=(document.getElementById&&document.all&&document.styleSheets)?1:0;
nn6=(document.getElementById&&!document.all)?1:0;

xConfirmStart=800;
yConfirmStart=100;

if(ie5||nn6) {
if(ie5) cs=2,th=30;
else cs=0,th=20;
document.write(
    "<div id='jsconfirm'>"+
        "<table>"+
            "<tr><td id='jsconfirmtitle'></td></tr>"+
            "<tr><td id='jsconfirmcontent'></td></tr>"+
            "<tr><td id='jsconfirmbuttons'>"+
                "<input id='jsconfirmleft' type='button' value='' onclick='leftJsConfirm()' onfocus='if(this.blur)this.blur()'>"+
                "&nbsp;&nbsp;"+
                "<input id='jsconfirmright' type='button' value='' onclick='rightJsConfirm()' onfocus='if(this.blur)this.blur()'>"+
            "</td></tr>"+
        "</table>"+
    "</div>"
);
 }

           document.write("<div id='jsconfirmfade'></div>");


function leftJsConfirm() {
document.getElementById('jsconfirm').style.top=-1000;
document.location.href=leftJsConfirmUri;
}
function rightJsConfirm() {
document.getElementById('jsconfirm').style.top=-1000;
document.location.href=rightJsConfirmUri;
}
function confirmAlternative() {
if(confirm("Scipt requieres a better browser!"))       document.location.href="http://www.mozilla.org";
 }

leftJsConfirmUri = '';
rightJsConfirmUri = '';

/**
 * Show the message/confirm box
*/
function showConfirm(confirmtitle,confirmcontent,confirmlefttext,confirmlefturi,confirmrighttext,confirmrighturi)  {
document.getElementById("jsconfirmtitle").innerHTML=confirmtitle;
document.getElementById("jsconfirmcontent").innerHTML=confirmcontent;
document.getElementById("jsconfirmleft").value=confirmlefttext;
document.getElementById("jsconfirmright").value=confirmrighttext;
leftJsConfirmUri=confirmlefturi;
rightJsConfirmUri=confirmrighturi;
xConfirm=xConfirmStart, yConfirm=yConfirmStart;
if(ie5) {
    document.getElementById("jsconfirm").style.left='25%';
    document.getElementById("jsconfirm").style.top='35%';
}
else if(nn6) {
    document.getElementById("jsconfirm").style.top='25%';
    document.getElementById("jsconfirm").style.left='35%';
}
else confirmAlternative();
}

Create simple html file

<html>
<head>
<title>jsConfirmSyle</title>
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Script-Type" content="text/javascript" />
<script type="text/javascript" src="jsConfirmStyle.js"></script>
<script type="text/javascript">

 function confirmation() {
 var answer = confirm("Wanna visit google?")
 if (answer){
    window.location = "http://www.google.com/";
}
}
  </script>
   <style type="text/css">
    body {
  background-color: white;
   font-family: sans-serif;
  }
#jsconfirm {
border-color: #c0c0c0;
border-width: 2px 4px 4px 2px;
left: 0;
margin: 0;
padding: 0;
position: absolute;
top: -1000px;
z-index: 100;
}

#jsconfirm table {
background-color: #fff;
border: 2px groove #c0c0c0;
height: 150px;
width: 300px;
}

#jsconfirmtitle {
background-color: #B0B0B0;
font-weight: bold;
height: 20px;
text-align: center;
}

#jsconfirmbuttons {
height: 50px;
text-align: center;
}

#jsconfirmbuttons input {
background-color: #E9E9CF;
color: #000000;
font-weight: bold;
width: 125px;
height: 33px;
padding-left: 20px;
}

#jsconfirmleft{
background-image: url(left.png);
}

#jsconfirmright{
background-image: url(right.png);
}
</style>


 <p>
<a href="#"  onclick="javascript:showConfirm('Please confirm','Are you really sure to visit google?','Yes','http://www.google.com','No','#')">JsConfirmStyled</a> </p>
<p><a href="#" onclick="confirmation()">standard</a></p>
