How to make StackOverflow like message box using CSS and Jquery ?

I have always been a fan of stackoverflow’s message box, so today I decided to re-create and share a similar message box just for fun ! Below is how stackoverflow’s message box looks like…

Below is what I have come up with at…

Html code :

<div class="error-box" style="display: block; ">

Javascript code :

$(".error-box").append("<p>Some Random Message inside the box.</p>" + "<span>(click on this box to dismiss)</span>" );
$(".error-box").bind("click", function(){

CSS code :

.error-box {
    z-index: 1;
    cursor: pointer;
    display: none;
    position: absolute;
    padding: 15px;
    -moz-box-shadow: 2px 2px 5px #000000;
    -webkit-box-shadow: 2px 2px 5px black;
    box-shadow: 2px 2px 5px black;
    color: #333 !important;
    background-color: #E3E3E3 !important;
    font-family:Segoe UI;
