Image popup on page load using HTML and jQuery

In this article, you will learn how to show a popup image on page load with a cancelling button using HTML and jQuery. This requires only the basic knowledge of HTML, CSS, and jQuery.

It is very common whenever you visit any site. You will generally see that once the page is loaded, a popup notification or a popup image shows up in the middle. The user can put some messages or images in the popup window. It can also have the closing option to close the window, or a user can also close the window by clicking outside of the popup box.

We usually use a popup image as a banner to tell our visitors something important. In the current web applications, there are numerous events where the developer needs to utilize this sort of image popup when the page loads. There are numerous jQuery Image popup plugins available at this point. But the major disadvantage is that they are going beyond expectations. As, the majority of the jQuery plugins for popups are much more advanced and cause much loading time. Instead of these, just go to this straightforward code and implement a simple image popup on page load.

First of all, we need HTML and CSS code to set the div at the centre of the web page and then write jQuery code to hide and show the centre of the div element.

index.html

Create and open your HTML file on which you need to insert the image popup and put the following code.

<!DOCTYPE>
<html>
<head>
    <title>Show the image on page load using jQuery</title>
</head>
<body>
    <div class='popup'>
        <div class="img">
            <img src="images/quit.png" alt='quit' class='x' id='x' />   
            <img src="img/codesolutions.png" />
        </div>
    </div>
</body>
</html>

CSS Code

Place the following CSS code in the head section of your html file to provide a good look and layout-

<style type="text/css">
#container
{
	width: 100%; height: 100%;
	position: fixed; top: 0;left: 0;
	z-index: 100; display: none;
	background-color: #808080;
	filter: alpha(opacity=70);
	-moz-opacity: 0.7;-khtml-opacity: 0.7; opacity: 0.7;
}
.window a { text-decoration: none; }
.popupbox
{
	width: 100%; margin: 0 auto;
	display: none; position: fixed; z-index: 101;
}
.window
{
	width: 360px; height:266px;
	min-width: 362px; min-height: 95px;
	margin: 80px auto; padding: 1px; background: #e6e6e6;
	position: relative; z-index: 103; border-radius: 5px;
	box-shadow: 0 2px 5px #000;
}
.window p
{
	color: #555555; clear: both;
	text-align: justify;
}
.window p a { color: #d91900; font-weight: bold;}
.window .close
{
	width: 34px; height: 35px; top: -25px; left: 22px;
	float: right; position: relative;
}
.window .close:hover { cursor: pointer;}
</style>

jQuery Code

Put the following jQuery code in the head section of your HTML file-

<script type='text/javascript'>
        $(function () {
            var container = $('<div id="container"></div>');
            container.show();
            container.appendTo(document.body);
            $('.popupbox').show();
            $('.close').click(function () {
                $('.popupbox').hide();
                container.appendTo(document.body).remove();
                return false;
            });
            $('.close').click(function () {
                $('.popupbox').hide();
                container.appendTo(document.body).remove();
                return false;
            });
        });
</script>
