I have tried almost all of the jQuery Modal plugins I can find on the net but they are all much to bulky for what I need. I don't need all the fancy features, I want to be able to open a div and have the background of the page go transparent grey like the photo below and have my div be on top of it, that is all I need to do so I would like to write some jQuery to do this instead of using a bulky plugin. Does anyone have any small code that can do this task? Is the transparent background an image or just CSS?
EDIT: This is obviously outdated. So please refer to Andrew Odri post below.
I don't know how good you are in CSS and JavaScript, but your request shouldn't be that hard to do yourself.
body, html { margin:0; padding:0; }
#modalTabelGray
{
position:absolute;
width:100%;
height:100%;
background-color:#000000;
filter:alpha(opacity=60);
opacity:0.6;
-moz-opacity:0.6;
z-index:100;
text-align:center;
vertical-align:middle;
}
#modalDiv
{
position:absolute;
z-index:101;
}
I haven't tested the code, might not work, but you'll get the idea.
This is what I use myself; it looks nice, the code is simple and easy to understand, and uses minimal CSS and jQuery.
Here is the code (And a fiddle to see it in action: http://jsfiddle.net/cadkJ/125/):

<button id="modal-launcher">Launch Modal Window</button>
<div id="modal-background"></div>
<div id="modal-content">
<button id="modal-close">Close Modal Window</button>
</div>
CSS
#modal-background {
display: none;
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: white;
opacity: .50;
-webkit-opacity: .5;
-moz-opacity: .5;
filter: alpha(opacity=50);
z-index: 1000;
}
#modal-content {
background-color: white;
border-radius: 10px;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
box-shadow: 0 0 20px 0 #222;
-webkit-box-shadow: 0 0 20px 0 #222;
-moz-box-shadow: 0 0 20px 0 #222;
display: none;
height: 240px;
left: 50%;
margin: -120px 0 0 -160px;
padding: 10px;
position: fixed;
top: 50%;
width: 320px;
z-index: 1000;
}
#modal-background.active, #modal-content.active {
display: block;
}
jQuery
$(function(){
$("#modal-launcher, #modal-background, #modal-close").click(function() {
$("#modal-content, #modal-background").toggleClass("active");
});
});
Do you want to lock scrolling?
Add the following CSS rule:
body.active { position: fixed; overflow: hidden; }
Replace the jQuery function with: (body added to line 3)
$(function(){
$("#modal-launcher, #modal-background, #modal-close").click(function() {
$("body, #modal-content, #modal-background").toggleClass("active");
});
});
Do you want to prevent click events on the background from closing the modal?
Replace the jQuery function with: (#modal-background removed from line 2)
$(function(){
$("#modal-launcher, #modal-close").click(function() {
$("#modal-content, #modal-background").toggleClass("active");
});
});
SimpleModal does precisely what you want to do.
You can use jQuery UI which has a dialog plugin that supports modal .. http://jqueryui.com/demos/dialog/#modal
Alternatively you would create a div that spans the whole viewport in size, set its opacity to 50% (0.5) and also catch and stop all events to make it modal. Then display your div on top of it ..
I've been using the jQuery UI Dialog for this. http://jqueryui.com/
You can create a simple modal using pure HTML and css,no need of javascript and jquery,which will indirectly reduce time and work.
html-->
<a href="#openModal">Open Modal</a>
<div id="openModal" class="modalDialog">
<div> <a href="#close" title="Close" class="close">X</a>
<h2>Modal Box</h2>
<p>This is a sample modal box that can be created using the powers of CSS3.</p>
<p>You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.</p>
</div>
</div>
css-->
.modalDialog {
position: fixed;
font-family: Arial, Helvetica, sans-serif;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0, 0, 0, 0.8);
z-index: 99999;
opacity:0;
-webkit-transition: opacity 400ms ease-in;
-moz-transition: opacity 400ms ease-in;
transition: opacity 400ms ease-in;
pointer-events: none;
}
.modalDialog:target {
opacity:1;
pointer-events: auto;
}
.modalDialog > div {
width: 400px;
position: relative;
margin: 10% auto;
padding: 5px 20px 13px 20px;
border-radius: 10px;
background: #fff;
background: -moz-linear-gradient(#fff, #999);
background: -webkit-linear-gradient(#fff, #999);
background: -o-linear-gradient(#fff, #999);
}
.close {
background: #606061;
color: #FFFFFF;
line-height: 25px;
position: absolute;
right: -12px;
text-align: center;
top: -10px;
width: 24px;
text-decoration: none;
font-weight: bold;
-webkit-border-radius: 12px;
-moz-border-radius: 12px;
border-radius: 12px;
-moz-box-shadow: 1px 1px 3px #000;
-webkit-box-shadow: 1px 1px 3px #000;
box-shadow: 1px 1px 3px #000;
}
.close:hover {
background: #00d9ff;
}

To name another plugin for this task is nyromodal which I find easy to use but still offers a lot of setting options if you should find yourself in the need for that (later)
