Standards-Based CSS/XHTML Slide Show 175

sootman writes "Eric Meyer, the man behind the famous Complex Spiral (CSS) Demo page, is at it again. He has created S5, "a slide show format based entirely on XHTML, CSS, and JavaScript." As he says, "With one file, you can run a complete slide show and have a printer-friendly version as well. The markup used for the slides is very simple, highly semantic, and completely accessible." So it can be used for PowerPoint-like work and the show responds to a variety of input--you can go to the next slide by pressing Return, Right, Space, etc. It is being released under a Creative Commons license. So fire up our favorite standards-compliant browser and check it out!"

    S5: A Simple Standards-Based Slide Show System

    S5 is a slide show format based entirely on XHTML, CSS, and JavaScript. With one file, you can run a complete slide show and have a printer-friendly version as well. The markup used for the slides is very simple, highly semantic, and completely accessible. Anyone with even a smidgen of familiarity with HTML or XHTML can look at the markup and figure out how to adapt it to their particular needs. Anyone familiar with CSS can create their own slide show theme. It's totally simple, and it's totally standards-driven.

    As a bonus, its markup is compatible with the Opera Show Format, and S5 is engineered to be displayed using Opera Show when a presenation is run using Opera.

    If you'd like to see S5 in action, go ahead and run through the introductory slide show [] (also available as an 95KB ZIP archive [], the size of which is due to the presence of several images in the slide show). Feel free to try any of the features. For example, you can hit the space bar to advance to the next slide. Or use the right arrow, the down arrow, hit Return... any of these will work. The other features will be explained in, or else demonstrated by, the slide show itself.

    If you like the general idea of S5 but don't like the theme used for the intorductory slide show, then fear not: there are already a number of themes [] available, and you can of course always create your own.

    If you have a hankerin' to know more about how this system works, exactly, we have a few resources that might help.

    • A Basic Primer in Using S5 [] pretty much what it sounds like.
    • S5 Reference [] a full reference describing what markup is required, what is recommended, and what is optional in an S5 presentation file.
    • Minimal S5 Structure [] a guide to the absolute bare minimum markup used in an S5 slide file.
    • S5 File Map [] explains what files are where, and what each one does.

    This is an excellent example of the Web applications that Microsoft feared. Even though it is crude, and it has one killer limitation:

    * Fonts are not scaled based on display resolution and available pixels; manual CSS editing is required

    And a massively annoying one:

    * Only one author can be listed in the metadata

    I'm not quite sure why the second limitation exists. But already this program does all of the important functions I need Powerpoint for, and it has one big advantage over powerpoint .. the html version looks far prettier on the web than powerpoint does.

    I was highly intrigued to learn about Opera's powerpoint alternative and previous attempts in this direction. This may be the first web app that I use all the time.

    • Out of curiosity, do you think there would be any practical interest for a web-based slide system that would:
      - scale slides (automatically) to match the current display,
      - allow obligatory slide transition effects on IE (and still work otherwise on any modern browser,)
      - offer a wysiwyg editing system to create simple slide shows, for people that don't feel like editing html?

      I kinda see how to put all that together, but it's unclear to me if there's a point.

    Some of the things I've seen in the past (like the Complex Spiral site) have amazed me, but this demo REALLY shows why XHTML and CSS is so great.

    So I open it up and it's a normal looking web page that is well done and works great. When your browser lacks javascript (or it's turned off) it looks like any other well made page. This is probably why it prints well too. Then you turn on javascript (or in my case let the little security warning from IE that came with SP2 run the script) and it's just like looking at a powerpoint presentation of the exact same data. Add a few other sets of CSS stuff and you could make it also look great for a handheld (like a Palm or some such) that might not be able to display the webpage well (assuming they can't handle the powerpoint style part here).

    And it's all just XHTML, CSS, and JavaScript. Amazing the things that can acomplish wihtout needing Java, ActiveX, Flash, a seperate viewer (like PowerPoint), etc.

    When you get someone really skilled with some pieces of technology, it's amazing the stuff they can crank out.

    I know the site is down (it was for me) but get a mirror of the zip file (there are ones in other comments) and check it out if you have even the tiniest interest in this.

      Javascript and HTML are very very capable. It's not hard at all to do complex things with them, as long as you can encapsulate everything into the one file. Accessing the file system, or databases, can pose a security risk. That's probably why as far as I can tell there are no good standards-based ways of doing these with just HTML, CSS asnd JS.

      • I've never known Eric to claim to be a graphic designer. The impressive part is not the visual design. There's no doubt that the Zen Garden contributors could whip up more beautiful visuals.

      • If you are referring to the ComplexSpiral home page, you are not correct. Those are 4 normal image files, all positioned with CSS, each one the same image just lightened or darkened (I used GraphicConverter on my Mac). No transparency, no .png. I used the same code on my site [], with a simple Javascript slideshow for fun. The backbround images don't work right in IE (big surprise). Read the ComplexSpiral site for the reason why.

    If OpenOffice built this into its presentation software. It would be nice if when you save your presentation you have the option to save as an XHTML document. This would dramatically reduce file size and allow OpenOffice to be used more widely (in my opinion) for some web applications. How hard could it be to port this format (since it is open) to OpenOffice? Any Volunteers?
    • that really is the a boost that would push OOo to the next level of usage, something useful that MS does not provide at all, and which would be used by companies.
      • Just some simple crash-recovery controls and a way to speed it up would be a big improvement. I went to move over to it from Microsoft Word and was severly dissapointed by how damn slow it was and the fact that when I went to save it crashed and then didn't have any way for me to recover my lost data.

        Perhaps it's better on non-Windows, but at the moment Word (unfortunately) shits all over OOo.
        • odd, i had *better* crash recovery (yes it does have it) than Office. I do agree that it is slow, I suggest abiword and other lightweight programs iinstead if your machine is too slow with OOo, hopefully this will improve in the future

The reality is, IE is still the hugely dominant browser, so any solution you present has to be compatible with it if it's going to be of any real commercial interest.
