Show a div as a modal pop up
I have the following div:
You must select a language.

A simple modal pop up div or dialog box can be done by CSS properties and little bit of jQuery.The basic idea is simple:
-
1. Create a div with semi transparent background & show it on top of your content page on click.
-
2. Show your pop up div or alert div on top of the semi transparent dimming/hiding div.
So we need three divs:
- content(main content of the site).
- hider(To dim the content).
- popup_box(the modal div to display).
First let us define the CSS:
#hider
{
position:absolute;
top: 0%;
left: 0%;
width:1600px;
height:2000px;
margin-top: -800px; /*set to a negative number 1/2 of your height*/
margin-left: -500px; /*set to a negative number 1/2 of your width*/
/*
z- index must be lower than pop up box
*/
z-index: 99;
background-color:Black;
//for transparency
opacity:0.6;
}
#popup_box
{
position:absolute;
top: 50%;
left: 50%;
width:10em;
height:10em;
margin-top: -5em; /*set to a negative number 1/2 of your height*/
margin-left: -5em; /*set to a negative number 1/2 of your width*/
border: 1px solid #ccc;
border: 2px solid black;
z-index:100;
}
It is important that we set our hider div's z-index lower than pop_up box as we want to show popup_box on top.
Here comes the java Script:
$(document).ready(function () {
//hide hider and popup_box
$("#hider").hide();
$("#popup_box").hide();
//on click show the hider div and the message
$("#showpopup").click(function () {
$("#hider").fadeIn("slow");
$('#popup_box').fadeIn("slow");
});
//on click hide the message and the
$("#buttonClose").click(function () {
$("#hider").fadeOut("slow");
$('#popup_box').fadeOut("slow");
});
});
And finally the HTML:
<div id="hider"></div>
<div id="popup_box">
Message<br />
<a id="buttonClose">Close</a>
</div>
<div id="content">
Page's main content.<br />
<a id="showpopup">ClickMe</a>
</div>
I have used jquery-1.4.1.min.js www.jquery.com/download and tested the code in Firefox. Hope this helps.
