HTML Utopia! Design Websites Without Tables – Parts 1 and 2

Welcome to HTML Utopia – the two part series on creating Web page designs without tables.

Part 1 introduces the concept of using CSS to create a design without tables, and explains the reasons why this philosophy has become so popular.

Part 2 explores a few standards-compliant commercial applications of this type of design, and exposes a few nifty tips and tricks to improve your CSS layout…

Enjoy!

This series sparked the idea that was eventually developed into SitePoint’s second print title, HTML Utopia: Desigining Without Tables Using CSS. Read four chapters from the book here.

HTML Utopia – Designing Without Tables: Part 1
Love at First ‘Site’!

A few weeks ago I stumbled upon a site that really inspired me. It was beautifully designed and presented. It was not until I looked at the code behind it that my heart truly skipped a beat.

The site was A List Apart, the brain child of Jeffrey Zeldman. Zeldman is also involved in WaSP – The WEB STANDARDS PROJECT that launched the browser upgrade campaign. The campaign encourages Users to upgrade to browsers that meet WC3 recommendations and lobbies the browser developers to build browsers that comply more thoroughly.

I decided to have a crack at rebuilding a SitePoint page without using any tables (currently there are 18 tables being used, 17 of which are unnecessary).

Editors Note: These examples are based on a previous SitePoint design and do not refer to the current site.

Click here to check it out. Have a look at the code if you don’t believe me (here’s the source). If you’re keen here’s the style sheet.

If all you saw was a not so pretty black and white page then I’m sure you’ll have some things to say about this article! You see, according to WaSP, your browser is not standards compliant. If it all looked fine to you then fire up your old copy of Netscape 4 and take a look at the same page…or click here for a simulated look!

When I’m talking about HTML Utopia, I’m talking about the separation of content from formatting. With databases we’ve achieved that separation to some degree but only on the production side. We’re still outputting our content into salami-like HTML code where we mix it with the cholesterol of <table> and <font> tags. Besides, not all websites are database driven and the ones that are rarely database 100% of their content.

Before I talk about the glories of such coding, let’s first address the backward compatibility issues with the older browsers.

Version 4 Bites!

As web designers and web developers, we’ve been busting our butts to get our creations to work across all browsers and over all platforms. By now, most of us have gladly committed the Version 3 browsers to the retirement home. However, we’re still suffering the shortcomings of the Version 4 browsers.

We’ve found our hacks and tricks that defy logic. We’ve developed our scripts to detect our user clients. We hold our breath as we Alt-Tab Control-R. Still, rarely do we manage to cover all bases and let’s face it – creating different code for different browsers which can’t even agree on the length of a text field is growing tiresome.

What’s the answer? Say "No!" to browsers who don’t comply with web standards. By web standards I mean CSS-1, HTML 4.01, and ECMAScript (the "official" version of JavaScript) – basically, any Version 4 or older browser? At this point the alarm bells start ringing.

With the release of Netscape 6 and Opera 5, we now have serious alternatives to Microsoft Internet Explorer who historically has provided the best support for CSS. If you’re looking for a Unix/Linux browser then Konqueror is available.

From my research, current stats indicate 77-80% of web surfers today are using browsers that do meet web standards. Maybe the remaining 20% need some encouragement.

When No means Yes

When I say No I’m not talking about serving a page to non-compliant browsers that resembles a 10 car pile up (due to its misuse of styles). And when I say No I’m not talking about a rude message and a closed door. What we can deliver is a nice message and your content! (If you haven’t loaded up your old browser yet here’s what it would look like.)

WaSP suggests that you use your message to encourage users with non-compliant browsers to upgrade and provide a link to an upgrade page.

One of the fantastic benefits of this approach is that you still present your content to a browser that doesn’t understand CSS. That includes any device capable of displaying files retrieved on the Internet eg. Hand-held devices, WAP Phones, Braille readers and Internet Fridges.

We don’t test for N4 and then serve the specially designed N4 content. We don’t test at all! By using an new alternative way of linking to our external stylesheet…

<style type="text/css" media="all">@import "styles.css";</style>

… non-compliant browsers (that don’t understand this method) will simply load the page without any styles. As long as you apply your styles with <p> tags and <h1>,<h2>…<h6> etc then your content will still make perfect sense in any browsing device. It will just look a little old school.

Need some more convincing? Lets look at the many other benefits.

CSS Happiness!

OK, we’ve talked about catering for all non-CSS devices including N4, even devices that haven’t been invented yet! There are some other great benefits of separating your content from your formatting.

Reduction in File Size:

I reduced the file size of the SitePoint page from 34,353 bytes to 18,585 bytes. It would be smaller again if it wasn’t for all those rounded corners!

One file controls the whole site design:

OK you’ve heard this before – it is part of the beauty of CSS in general. Should you decide to add Geneva to your font family because you’re becoming Mac friendly then modify your style sheet and the changes will be reflected across your whole site.

Alternative Style Sheets:

You can have a separate style sheet that is used when your page is printed. That means no more separate ‘print version’ pages.

Old Dogs and New Tricks

Those of you that code by hand should have no trouble making the transitions to this style of HTML and if you’re anything like me, you’ll get a kick out of doing something new. There’s bad news for those of you that rely on WYSIWYG software – at least in the short term – because there isn’t any programs with this level of CSS support. Macromedia is usually pretty quick, so you probably won’t have to wait too long. You might even find that once you get the hang of it coding like this is easier than fiddling with 100′s of table cells!

Good luck and May The Source Be With You.

Browser Stats

Back in Part I of HTML Utopia — Designing Without Tables, we introduced the idea of using CSS Positioning rather than tables for laying out Websites. In Part 1 we took a fairly discriminatory view of old browsers such as Netscape 4.

Part 2, below, is about solving the old browser problem in a less hostile way. We’ll also take a peek at a few techniques.

HTML Utopia – Desigining Without Tables: Part 2
I’m Back

It’s been over a year since I wrote my first (and only) article for SitePoint and I thought I should share the experiences I’ve since had designing without tables.

The response to Part 1 was very positive. Thanks! There were, however, a significant number of readers that did comment that they weren’t prepared to give Netscape the bum steer like I suggested.

A simple comment that significantly impacted my future approach to Web design came from Kevin Yank, who asked the question: "What about all the CSS that Netscape 4 can do?"

WaSP — The Web Standards Project

Back in Part 1, it was the WaSP campaign (via A List Apart) that got me started on this whole utopian trip. Since then I’ve learnt to strike a balance between the WaSP ideology, and the requirements of my commercially oriented clients.

I guess you could say it’s selling out, but let’s face it — our job is to satisfy our clients to the full extent of our abilities. I decided to look for ways to exercise my new passion for CSS Positioning while still giving Netscape a look-in.

Methods in the Madness

I think I can best illustrate some of the options I explored with some real life case studies. Before I begin, I should let you know that I work as a designer for SitePoint’s commercial Web design division, and the case studies I’m about to present are real live sites that I’ve worked on in my capacity as Web Development Manager for SitePoint.

If that offends you, then don’t read on. Otherwise, let’s get cracking!

Eyes on Diabetes — Pure CSS for New Browsers

This design is from the WaSP school of thought — Pure CSS, and the vanilla treatment for Netscape 4. Check it out in Netscape 4 — it’s surprising how neat and tidy you can make your non-CSS layout look.

Admittedly, a brief like this one is something of a luxury. Accessibility was priority number 1 for www.eyesondiabetes.org.au, and the use of Pure CSS was attractive because of the abstraction of presentation from content.

Here’s how the stylesheet is called:

<link type="text/css" media="all" rel="stylesheet"     
href="/includes/persistent.css" />

As I mentioned in Part 1, Netscape doesn’t understand either the @import method, or the media="all" attribute. By using either of these in your call to the stylesheet, you can ensure that Netscape won’t load it.

SitePoint.com.au — Pure CSS for All Browsers (even N4)

Editor’s Note: A year on from writing this article, we’ve redesigned www.sitepoint.com.au The site is now very stripped back for Netscape4.

For one of our own sites, SitePoint.com.au, I decided to take Kev’s idea to heart and let Netscape 4 have as much CSS as it could handle. Initially I expected that it might manage the fonts and colours, but not much else. What I actually found was that I could get the whole site to work in Netscape using CSS and no tables! The only hitch was that Netscape’s interpretation of percentages is pretty bizarre — this was the main point of contention.

In my first build I simply called two stylesheets — one of which Netscape skipped:

<link type="text/css" rel="stylesheet"     
href="/includes/basic.css" />    
   
<link type="text/css" media="all" rel="stylesheet"    
href="/includes/advanced.css" />

The basic stylesheet had pixel-based widths and margins locked in to fit an 800×600 resolution. The advanced stylesheet re-declared all those widths as percentages, so the layout spread to 100% of all screen resolutions.

I revisited the site a few months later and opted for a browser detection script instead. This enabled me to split my CSS into three stylesheets:

  • The common styles such as fonts, colours and backgrounds

  • The positioning styles for new browsers

  • The positioning styles for Netscape 4 My new stylesheet for Netscape 4 even managed to find a set of widths and margins that worked as percentages.ed for

    Editize.com — Two Distinct Layout Templates

    One of the features of the EditizeTM product is that it works in all browsers. Therefore it was important that the site looked as good as it could in Netscape 4.

    All the pages would use the one template, as most were databased and edited via a Content Management System.

    For template-based Websites, all content is displayed in a container. That container is typically a <div> or a <td>. For www.editize.com, I made two containing structures (layout files) into which our content could be inserted.

    379_code

    Then I simply used a browser detection script to choose the right template.

    Browser Detection Scripts

    A fair bit of thought has gone into how the browser detection scripts should work.

    It’s important to detect the old browsers like Netscape 4, in order to serve them their specially limited layout, while presenting every other browser with the new CSS layout. We do it this way, rather than pick out the new browsers, because:

  • We don’t want to keep modifying our script every time a new version of a browser is released.

  • We want the really old browsers (the ones you don’t usually have available to test your site on) to get the CSS layout — it’s better to err on the side of conservatism and ensure that they have no formatting at all (just to be on the safe side).

  • We want other devices such as Handhelds and Internet Fridges to get simpler CSS layout (always with the Internet fridges!).

  • We want the search engine robots to trawl our more efficient CSS layout.

    This is my PHP script (updated 5-20-03):

    // Grab Netscape 4 on all platforms     
    // (This isn't fullproof but it's pretty close)    
       
    $tmp = explode(" ", $HTTP_USER_AGENT);    
    $brvers = explode("/", $tmp[0]);    
    $brvers = (float)$brvers[1];    
       
    if ($brvers > 4.01 and $brvers < 4.99)    
     $version = "old";    
    else    
     $version = "new";    
           
    // Here's a 'find' function to      
    // specifically grab some other browsers    
       
    function find($component)      
    {      
    global $HTTP_USER_AGENT;      
    $result = stristr($HTTP_USER_AGENT,$component);      
    return $result !== FALSE;      
    }    
       
    // Use this to get IE5 on Windows (optional)    
       
    if ((find ('MSIE 5.0')) and (find('Win')))    
     $version = "old";    
       
    // At this stage WebTV seems to cope much    
    // better with a Netscape style page so      
    // lets grab it    
       
    if (find ('WebTV'))    
     $version = "old";

    You can I see I used the decimal increments to weed out Netscape 4. These increments are platform independent and in my experience not used by any other browsers.

    In the above script I chose to class IE5 as an old browser because it gets a lot of CSS wrong, and fewer people use it these days. Note that I specifically look for IE5 on Windows because the Mac version is a CSS-friendly browser.

    CSS Layout Techniques

    The following is an overview of the techniques you can use to lay out your pages with CSS. For an excellent article on CSS Positioning that goes into more detail check out BrainJar.com: CSS Positioning.

    Float

    Although this is not really the intended use for the CSS property "Float", this technique is a good, simple way to lay out 2 columns.

    379_float

    I prefer examples 3 and 4 of the above because:

  • Your main column content comes before your column. This will result in the document being rendered in the right order for voice browsers, and those browsers that ignore the stylesheet.

  • Your main content is likely to be longer than your skinny column, and you won’t want it to wrap the way it does in examples 1 and 2.

    Absolute Positioning

    The absolute positioning technique is another good option — especially for three column layouts.

    379_absolute

    Notice how our main layer spreads to a width of 100% and our columns sit on top. We use margins to stop the main column’s content from being overlapped.

    In theory, all layers could be absolutely positioned, but you’ll soon see why it’s a good idea to keep at least one of them (the longest column) relative.

    379_headnfoot

    Headers and Footers can easily be slotted in. Because our main layer is also relative, it simply stacks up right after the header. Our absolutely positioned layers need to have their distance from the top set, so that they line up with the bottom of the header.

    As long as we have a relatively positioned main layer, a Footer (which is also relatively positioned) will simply stack up after it. Therein lies a problem!

    The Footer Issue

    Our relatively-positioned layer (usually the main layer) must be longer than any other layers. If it’s not, we’ll get problems such as those illustrated in Figure 6.

    379_footer

    This can be a real problem for database-driven sites, because you often have automatically generated content that you don’t always plan for.

    For example, say you had your databased article displayed in the main column, and the names of other articles listed in the right column. After some time, your client (a prolific writer) has more articles listed in the right hand column than you ever anticipated, and a couple of very short articles. This will cause a problem such as that depicted in illustration 8.

    Another example is with short confirmation pages — such as a thank you message — as depicted in illustration 9.

    The answer? Be prepared. Put limits on your queries for dynamic columns and pad out any short pages with a few <p>&nbsp;</p>.

    Print StyleSheet

    While you’re at it, clean up your site for the printer. IE6, Netscape7 and Mozilla have good print previews that enable you to fine tune your Print Mode stylesheet without destroying forests.

    Call your Print Mode Stylesheet with:

    <link type="text/css" media="print"  rel="stylesheet"       
    href="/includes/print.css" />

    It’s pretty easy too. You can simply turn things off by setting the display property to none. I like to:

  • Hide my navigation system

  • Swap my logo for a black and white version

  • Change any pixel based font sizes to points

  • Add a letter head style business address to the top of each page

  • Make any adjustments to column widths

  • Change columns to position: relative; to make them follow my main content.

    Show’s Over

    This is probably just enough to whet your appetite. Remember, there are more and more browsers out there that support the standards for CSS. The ones I usually test on are:

  • Mozilla

  • Opera

  • Netscape

  • Internet Explorer

    Unfortunately there are still some minor idiosyncrasies amongst them, but on the whole it’s not too hard to get your site working across all of them.
