The rise of jQuery, MooTools, and JavaScript frameworks has given many web designers a new lease on life, adding more unique functionality into their sites.

Most notably among the various cool and interesting features you can find being injected into a design is the humble lightbox (modal window).



If you’ve ever come across a link or image which upon clicking increases in size and where the rest of the screen gets "shaded" to focus on the content, you’ll know what I’m talking about.

This tutorial aims to showcase a method of displaying content based on the lightbox, which is web accessible and (excluding Internet Explorer) will require no scripting at all. Sound like fun? Well, let’s explore the subject further!

What About Scripting?

There’s a lot to be said about the benefits of using client-side scripting for this. While we are certainly not in the cut-and-paste era that leads to the kind of crimes against JavaScript many coders would like to see punished, we do, to this day, still have an uncomfortable reliance on scripts and frameworks in order for our websites to function.

Perhaps it seems a little hypocritical in this instance for me to critique the use of scripting (as Internet Explorer users will require scripting enabled to use this functionality), but like all things, we sometimes need to compromise our code to ensure compatibility (especially with that browser)!

Why Not Just Use JavaScript?

In the sense of the current scripting frameworks, I’m not going to say that they are inherently bad because the likes of jQuery often gracefully degrade with good levels of success you guys can put away the knives and flame-lit torches now!

However, the sad facts are that, due to security issues, widespread abuse and the intrusive potential of client-side scripting, it’s quite easy to understand why a large number of people do not (or cannot) make use of scripting.

Therefore, a solution is required. And hopefully for you CSS3 fans, you’ll find this simple, easy-to-use code to be a welcome improvement.

Browser Support of this CSS Lightbox

To give you a quick introduction before we begin producing the code itself, it’s worth mentioning that I’ve tried the code in a variety of browsers and can say for sure that it works in all recent versions of Mozilla Firefox, Google Chrome, Apple Safari and Opera (which is all great news).

With a little bit of unobtrusive scripting that replicates the CSS3 techniques, it’ll also run smoothly within IE 6, 7 and 8.

The other fantastic news is that current test versions of IE9 support CSS3, so this may very well be the best JavaScript-free solution there is in the near future.

Internet Explorer is the usual culprit when it comes to lacking in standards support.

Magic Markup!

To begin our quest for a much more compatible lightbox, the first thing we need is some general HTML markup.

Much of the below won’t surprise you in the slightest as it’s pretty standard. However, for this example, and to showcase how durable this cool method is, we’ll produce three individual lightboxes.

One will be for an image, one will be for a block of scrollable content and the final one will hold a YouTube video. What more could you ask for?

To begin, let’s create the basics and have three fragment links which will go to the correct lightbox (you’ll learn how a bit later on).

You can use this fantastic solution to create lightboxes for not just images but rich, semantic content and video's as well!

Not much going on at this stage, a simple HTML document with extra links.

So far, things are pretty simple; you have a heading and paragraph with some links that, upon clicking, will currently do nothing.

The next stage in the process, however, is all important.

We need to add the container for each lightbox to appear within and give them their appropriate values.

To give you an idea as to how each of the three lightboxes work, you’ll need to examine (and add) the code into your source code editor.

To better understand how it works, let’s talk about each item individually.
