Login Box Modal Dialog Window with CSS and jQuery

September 20, 2011

Hello guys, in this tutorial will introduce how to create a simple modal dialog window with jQuery by using of a login box. This tutorial requires intermediate knowledge of CSS and jQuery. For best results, please be sure to learn the basic of JQuery.


The markup is simple and also very versatile, in addition to make a login box, you can create content that is displayed only by clicking the link, use this tutorial to release all your creativity.

<a href="#login-box" class="login-window">Login / Sign In</a>

Now create a contact form and add the close button

<div id="login-box" class="login-popup">
<a href="#" class="close"><img src="close_pop.png" class="btn_close" title="Close Window" alt="Close" /></a>
  <form method="post" class="signin" action="#">
        <fieldset class="textbox">
        <label class="username">
        <span>Username or email</span>
        <input id="username" name="username" value="" type="text" autocomplete="on" placeholder="Username">
        <label class="password">
        <input id="password" name="password" value="" type="password" placeholder="Password">
        <button class="submit button" type="button">Sign in</button>
        <a class="forgot" href="#">Forgot your password?</a>


The CSS might be a bit more complicated, but look you have any comments you explain in more detail this process. In this example i used the CSS3 rules.

/* Mask for background, by default is not display */
#mask {
    display: none;
    background: #000;
    position: fixed;
    left: 0;
    top: 0;
    z-index: 10;
    width: 100%;
    height: 100%;
    opacity: 0.8;
    z-index: 999;

/* You can customize to your needs  */
.login-popup {
    display: none;
    background: #333;
    padding: 10px;
    border: 2px solid #ddd;
    float: left;
    font-size: 1.2em;
    position: fixed;
    top: 50%;
    left: 50%;
    z-index: 99999;
    box-shadow: 0px 0px 20px #999;
    /* CSS3 */
        -moz-box-shadow: 0px 0px 20px #999;
    /* Firefox */
        -webkit-box-shadow: 0px 0px 20px #999;
    /* Safari, Chrome */
	border-radius: 3px 3px 3px 3px;
    -moz-border-radius: 3px;
    /* Firefox */
        -webkit-border-radius: 3px;
    /* Safari, Chrome */;

img.btn_close {
    Position the close button
	float: right;
    margin: -28px -28px 0 0;

fieldset {
    border: none;

form.signin .textbox label {
    display: block;
    padding-bottom: 7px;

form.signin .textbox span {
    display: block;

form.signin p, form.signin span {
    color: #999;
    font-size: 11px;
    line-height: 18px;

form.signin .textbox input {
    background: #666666;
    border-bottom: 1px solid #333;
    border-left: 1px solid #000;
    border-right: 1px solid #333;
    border-top: 1px solid #000;
    color: #fff;
    border-radius: 3px 3px 3px 3px;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;
    font: 13px Arial, Helvetica, sans-serif;
    padding: 6px 6px 4px;
    width: 200px;

form.signin input:-moz-placeholder {
    color: #bbb;
    text-shadow: 0 0 2px #000;

form.signin input::-webkit-input-placeholder {
    color: #bbb;
    text-shadow: 0 0 2px #000;

.button {
    background: -moz-linear-gradient(center top, #f3f3f3, #dddddd);
    background: -webkit-gradient(linear, left top, left bottom, from(#f3f3f3), to(#dddddd));
    background: -o-linear-gradient(top, #f3f3f3, #dddddd);
    filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#f3f3f3', EndColorStr='#dddddd');
    border-color: #000;
    border-width: 1px;
    border-radius: 4px 4px 4px 4px;
    -moz-border-radius: 4px;
    -webkit-border-radius: 4px;
    color: #333;
    cursor: pointer;
    display: inline-block;
    padding: 6px 6px 4px;
    margin-top: 10px;
    font: 12px;
    width: 214px;

.button:hover {
    background: #ddd;


The first step is to call the jQuery file.

<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script>

Create a new script tag and insert the code.

$(document).ready(function() {
$('a.login-window').click(function() {
            //Getting the variable's value from a link 
    var loginBox = $(this).attr('href');

    //Fade in the Popup
    //Set the center alignment padding + border see css style
    var popMargTop = ($(loginBox).height() + 24) / 2; 
    var popMargLeft = ($(loginBox).width() + 24) / 2; 
        'margin-top' : -popMargTop,
        'margin-left' : -popMargLeft
    // Add the mask to body
    $('body').append('<div id="mask"></div>');
    return false;

// When clicking on the button close or the mask layer the popup closed
$('a.close, #mask').live('click', function() { 
  $('#mask , .login-popup').fadeOut(300 , function() {
return false;

The Logic

  1. .append
    The .append() method inserts the specified content as the last child of each element in the jQuery collection.
    For more information see here .append()
  2. .live()
    This method is a variation on the basic .bind() method for attaching event handlers to elements. The .live() method which will tell jQuery to bind any current and future references of “#login-box” to the click event.
    For more information see here .live()


We created a simple modal dialog window using jQuery and login box with CSS3. If anyone has any questions, advice, or comments please feel free to let me know!

  2. Really useful publish..Thanks for sharing with us. it will be very useful while functioning.. Thanks a LOT!!s

  3. Bruce

    Nice simple implementation, but client is complaining that the login box doesn’t appear when using FireFox on an Ipad. Since I don’t have an Ipad, no idea of what the problem might be.

  4. Nice Login Style..


  5. viral

    i agree with kumar.When clicking on submit button ,no event is called.

  6. Hello,

    The attribute ‘Type’ of the button should be ‘submit’ and not ‘button’. The form would be submit after this modification.

  7. thanks buddy,,, :)

    Brilliant, thank you this helped me a lot! I am a little confused as to how I can incorporate false password denial into this? No matter what password or username I enter, it always allows access to the form action I set…

    Can anyone help me?

  20. Thanks. It would be convenient if you provided a zip of all the code, but what you have here is great.

    Works fine with me, but when i click on close button, did’t work with me, can you help me???

  27. This is fantastic!! Thank you very much. I have incorporated it into my WordPress plugin for using a modal help popup for each option. It’s BEAUTIFUL!!

    One question… is it possible to add a scroll bar for when the content within the modal window becomes too long for the screen? Currently, it just “squeezes” what it can into the screen.

    Otherwise… Awesome!!

  28. Thank you !
    Can you share code this application.
    it doesn’t work with me :(

  29. Ronald

    Just letting everyone know that if you copy and pasted the code and it’s not working, it’s likely because the jQuery src is incorrect on his explanation code. He writes:


    where it should be:

    Say I want to include two of these pop up on the same page. One for signing in and another for registering how do I go about that?

    Sorry if the following is not clear…
    This is what I tried.
    I have created another div and id=register-box and class=register-popup. I have modified the form to include the necessary fields.
    I have changed the css file and updated it to include .register-popup
    I have copy what was to be included in the script tags and pasted it (still inside the $(document).ready(). In the script I have changed all the variables accordingly. But it does not work.

    Any help will be greatly appreciated it.


  62. Singh

    Alright so after some debugging this is what I have narrowed down my problem to…

    basically in my script tag I have the following:
    begin script tag
    $(document).ready(function () {
    $(‘a.login-window’).click(function () {

    $(document).ready(function () {
    $(‘a.register.window’).click(function () {
    /* same code as ‘a.login.window’ with exception of approriae renames. */

    End script tag.
    So basically what I have determined is that when I click on the register link (which I created similarly to login link as you described above) the jquery code ‘a.register.window’ never executes. How do I fix this?

    Again, thanks in advance.

  63. Singh

    Okay, never mind I solved my problem. Thanks for the great tutorial.

  64. Neil Patel

    How could you incorporate this into an emial form?

  65. JY
