A Internet Designer’s Journey – A Record Aside

It is a journey from six years of standard net design follow to the best way we’ll construct websites sooner or later. Solely it’s not set sooner or later. You’re soaking in it.

Article Continues Beneath

From the start, we’ve executed no matter we needed to do to make our websites work in each browser. On this planet of non-standard HTML Design, we bolt each phrase, each picture into place by manipulating desk cells.

And we remedy issues by changing them with new ones. Netscape 4 ignores the CSS {margin: 0;} declaration? Prolong the BODY tag with the 4 Horsemen of Non-Validation: LEFTMARGIN, TOPMARGIN, MARGINWIDTH, MARGINHEIGHT. IE4 doesn’t totally help the CSS border property? Nhái it by wrapping a black HTML desk round your white one. Positive, it shouldn’t work, nevertheless it does, and this website was due yesterday. Construct, check, rebuild.

That’s how websites received inbuilt 1995, and it’s how they’re constructed immediately. It’s a messy, complicated enterprise whose lack of logic created a marketplace for visible net editors like Dreamweaver, GoLive, and FrontPage. In the meantime, we hand-coders typically pleasure ourselves, not on the standard of our work however as a substitute on our arcane information of which non-standard tag or snippet of JavaScript “fixes” which rendering downside wherein silly browser.

We complain concerning the WYSIWYG editors, however we write the identical sort of code ourselves. After we don’t know the right way to do one thing, as a substitute of consulting the W3C or ECMA requirements, we share hacks on mailing lists or throughout the cubicle. And when a browser comes out that really helps requirements, we complain about the best way it breaks our HTML workarounds and browser-specific “DHTML.”

It is a mighty silly solution to work. But it surely will get worse when now we have to revamp. Except we work with proprietary publishing techniques (which have issues of their very own), all that previous content material riddled with FONT tags and caught inside desk cells needs to be poured into our new templates by hand – one web page, one desk cell, at a time.


Everyone knows the long run is about net requirements. And net requirements are concerning the separation of favor from content material – presentation from construction – design from information.

Everyone knows that there are browsers in the marketplace proper now that kind of utterly help these net requirements. IE5, Netscape 6, and Opera 5 provide CSS, HTML, and JavaScript/ECMAScript compliance strong sufficient to allow us to discard the clumsy strategies of the previous, and liberate the online from the bondage of HTML Design.

We additionally know that hundreds of thousands of individuals view the online by way of 4.0 and older browsers. And this information prevents us from crossing the road and implementing tomorrow’s net strategies proper now.

I crossed the road.


Horror films educate us by no means to enter a darkish room alone. Earlier than embarking on a very new method of designing web sites, I discovered stalwart companions to accompany me into the darker corners.

Two of those courageous souls have been CSS specialists who had helped create the requirements within the first place; as they select to stay nameless, I’ll seek advice from them as Nameless Donors A and B.

Later within the quest, ALA’s David Eisenberg joined our small band of adventurers, working cross-platform exams and intentionally altering our rising model sheet to confirm numerous ranges of CSS compliance on a browser-by-browser foundation.


If you concentrate on it, there are two methods to create standards-compliant websites: one which complies with the letter of net requirements, and the opposite that complies with their spirit.

The protected, conservative method follows the letter of net requirements by avoiding validation errors. But it surely falls in need of the spirit of net requirements by persevering with to bind model to content material in chains of iron.

As an illustration, the WaSP’s website has all the time been standards-compliant, and has all the time used CSS to regulate its typography. However the format is finished with HTML tables so the positioning will work in any desktop browser.

The profit: what I simply mentioned – it really works in any browser. The drawbacks:

  1. Altering the design means hand-editing hundreds of particular person desk cell colours, heights, and widths, or crafting new desk layouts – a time-consuming and dear course of.
  2. These HTML format strategies are meaningless to non-traditional browsers and are thought of dangerous by the W3C, even when the pages validate.
  3. These conventional strategies make pages much less accessible to individuals and gadgets.

After which there’s the second method, the Holy Grail of net requirements: separating model from content material, utilizing structural markup for information, and CSS for all elements of visible format management. I’d been utilizing CSS since 1997, however had by no means cranked the amount to 11. Now, with assist from my pals, I’d just do that.

The normal ALA format was a maze of intricately nested HTML desk cells. When updating it up to now, even I couldn’t comply with the aim of a few of these complexly interdependent column spans and row spans – and I had created the rattling factor.

<!-- Gown left -->
 <desk border="0" cellpadding="0" 
<!-- Your variable left margin -->
 <tr valign="prime"><td width="15%" 
 bgcolor="#ffffcc"> </td>
 <td width="75%" bgcolor="#ffffcc" 
<!-- Your precise content material -->

Might now we have that in English, please? I ached like a boy on Promenade Evening on the considered changing 10,000 maniacal desk cells with two or three clear, easy HTML DIVs.


That is pretty much as good a spot as any to boost the difficulty of rethinking your format as you progress from HTML Design to CSS – as a result of that’s precisely what I did at this level. The normal HTML format was a three-paneled liquid affair; it squashed and stretched to accommodate your monitor. I wished to recreate that liquidity in CSS, however I wasn’t eager on reproducing all three panels.

[The traditional ALA brand panel.]


I made a decision that the highest panel – the acquainted orange model panel – was pointless, and doubtless all the time had been. Any further, branding may very well be dealt with within the content material panel itself.

Frankly, making a three-paneled format in CSS additionally appeared near not possible to realize, although such capabilities are deliberate for CSS-3. {Really, a three-panel format is comparatively simple to realize in CSS, as seen in these examples by Porter Glendinning and your humble creator. However on the time of the primary ALA CSS redesign, the issue appeared daunting. – Ed.}

It’s simple to do absolute positioning in CSS, and that’s the a part of the usual that almost all net designers soar on. However liquid design can’t be achieved with pixel-perfect positioning. For a website to squash and stretch, the design components should be sized and positioned in relative, not absolute, phrases. This type of factor is straightforward to do in HTML tables, and it’s another excuse tables have held on so long as they’ve. How may it’s executed with model sheets?

My first thought, the plain one, was to create two HTML DIVs: one for content material, the opposite for the greenish thực đơn space at proper. And my first try almost did the job.  A “content material” DIV is asserted this manner within the embedded model sheet:

.content material {width: 75%; padding-left: 10%; padding-right: 10px; padding-top: 10px;}

The content material DIV takes up 75% of the width of the web page, and has a bit padding to create white house between its edges and filling. In the meantime, a “thực đơn” DIV is assigned to take up the remaining 25% of the width of the web page (and 100% of its top):

.thực đơn {place: absolute; left: 75%; prime: 0px; top: 100%; width: 25%; margin: 0; padding-left: 15px; padding-right: 10px; padding-top: 10px; background-color: #cc0; background-image: url(backgrounds/striperight.gif); font: 10px/14px geneva, arial, helvetica, sans-serif;  coloration: black; }

In IE5/Home windows, this labored as anticipated. However in browsers thought of to be much more standards-compliant than IE5/Win, I received horizontal and vertical scrollbars. (You’ll see them in IE5/Mac, Netscape 6, and Opera 5.)

What was up with that? 100% of a web page’s top was 100%, wasn’t it? 75% plus 25% nonetheless equalled 100%, didn’t it? Why have been these browsers messing up so badly?

The reply, after all, is that they weren’t. I used to be – as a result of I didn’t perceive the CSS field mannequin accurately (and neither did IE5/Win).


Memorize this: Within the CSS field mannequin, padding and borders are added to the general dimension.

A field 300 pixels large, with 20 pixels of internal padding, is 300 pixels large in IE/Home windows. That appears proper, nevertheless it’s improper in accordance with the CSS1 spec.
A field 300 pixels large, with 20 pixels of internal padding on either side, is 340 pixels large in CSS-compliant browsers (300 + 20 pixels on the left + 20 pixels on the correct). That’s as a result of padding, despite the fact that it happens on the INSIDE of the field, is added to the general width per the CSS1 spec.

Many net designers who wrestle with CSS have requested why IE and Netscape 6 deal with DIVs in another way. The reply is, on the Macintosh platform, they don’t. IE5/Mac and Netscape 6 (like Opera 5) get the CSS field mannequin proper. IE5/Win will get it improper. In Home windows, IE and Netscape differ as a result of Netscape will get the field mannequin proper. IE6, I can solely dream, will get it proper as effectively.

{Ed: Since this text was initially written and designed, the IE6 beta has been launched to the general public. It does certainly get the CSS field mannequin proper. This text was rewritten and redesigned on 7 April 2001 to accommodate these adjustments within the browser kingdom.}

This box-model brouhaha additionally explains why IE5 and Netscape 6 deal with border properties in another way. A ten pixel border is accurately added to the surface of the DIV, or paragraph, or no matter block-level ingredient on which it happens. In case you fill the whole display with a picture, and add a ten pixel border to that picture, you’ll get scrollbars in a very CSS-compliant browser, as a result of your general picture is now 20 pixels too massive for the display. In IE5/Win? No scrollbars. The way in which IE5/Win works appears preferable in some ways, nevertheless it’s improper.

IE5/Mac emulates non-standard IE5/Home windows conduct in Quirks mode, however delivers correct requirements compliance in Strict mode. You set off Quirks mode by leaving out the DOCTYPE or making a DOCTYPE with no W3C URL:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

You set off Strict mode by starting your web page with a DOCTYPE that features the related W3C URL:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 

The Gecko browsers (Mozilla, Netscape 6.x) comply with IE5/Mac’s lead, as does the IE6 beta [now IE6 — ed.]. In all these browsers, you should utilize DOCTYPES to regulate whether or not you need your website to adjust to requirements as written, or to emulate the conduct of older, much less compliant browsers.


Now you’ll be able to see why my first iteration of the ALA redesign was saddled with scrollbars. Add my padding and margins to the chances I used to be utilizing. 75% plus 25% equals 100%. Plus padding of 10% and 10 pixels for the content material DIV. Plus an extra 25 pixels for the thực đơn DIV. It’s a surprise it labored in any respect.

How was I going to work across the intractable exactitude of numbers and guidelines? I couldn’t precisely write this in my model sheet:


If I had been utilizing absolute widths, I’d simply specify these widths and let the web page be as large because it wanted to be. However that will lead to a static, print-like format that may be too large for some individuals’s screens, too slim for people’. I used to be making a liquid format. If I simply began fudging my numbers, they might by no means add up. It was clearly not possible to combine percentages and padding on this method with out creating absurdly unworkable totals: 103%? 104.25%? It might differ for every monitor, however it will all the time be improper.

At this level Nameless Donor A solved the field mannequin downside by considering outdoors the field.

FLOATIN’ & FUDGIN’#section15

As a substitute of conceiving of the ALA format as an off-white content material web page interrupted by a right-aligned thực đơn space, Nameless Donor A conceived of it as a inexperienced web page interrupted by a naturally left-aligned content material space. He then employed the little-used CSS “float” property to drift the content material to the specified width:

#content material   {
 float: left;
    width:  67%; 
    padding: 45px 10% 100px 15%; 
    margin: 0 15px 0 0;
    border-right: 2px dotted black;
    border-bottom: 2px dotted black;

Discover that the gif background picture utilized in my first draft format has been changed by the CSS border property (2px dotted black). Discover additionally that the proportion has shrunk from 75% to 67%.

Really, we decided that the perfect width was even narrower than that. In monitor settings beneath 800 x 600, a thực đơn space of 25% was insufficiently large. Consequently, thực đơn gadgets would slip right down to the underside of the web page (screenshot). The perfect width for the content material space turned out to be 52%. Keep in mind, that’s 52% earlier than the padding and margins are added. It’s possible you’ll need to go get drunk for some time, then come again and do this once more.

  1. Why hadn’t this downside cropped up within the previous ALA table-based layouts? As a result of table-based layouts are sloppy to start with. With a table-based format, in case your thực đơn space is just too slim, the browser merely fudges the proportions. CSS-compliant browsers won’t fudge proportions to avoid wasting you from your personal stupidity.
  2. If the perfect width was truly 52%, then why is the content material DIV declared at a width of 67%? Easy: 67% is a bogus worth to idiot Home windows IE5 into displaying the precise worth kind of accurately.

Keep in mind, IE5/Win will get the field mannequin improper by absorbing padding and margins with out adjusting the general width. 67% is roughly what 52% appears like after you add padding and margins.

I’m describing in a paragraph what took 14 hours to determine. It’s possible you’ll need to sniff glue for some time, then reread this while you get out of rehab.

From what I’ve mentioned to date, you may suppose my nameless cohorts and I made a decision to arrange the CSS format so it will solely work accurately in a much less standards- compliant (however extra broadly used) browser, IE5/Win. Not so.

Nameless Donor A used a CSS2 declaration to set the proper width:

physique>#content material {
 width: 52%; 
    padding: 35px 5% 100px 10%;

If physique># appears like a typo, it’s not; it’s a CSS2 selector. IE5/Mac, Netscape 6, and Opera 5 perceive CSS2 syntax. IE5/Home windows doesn’t, so it skips it. IE5/Win follows the rule it understands: the bogus 67% width. Extra conformant browsers comply with the CSS rule of higher specificity. What’s that, you ask?


A world model sheet declares that every one textual content within the <physique> of an online web page must be 1em Arial. However a paragraph is asserted to be .8em Verdana.  You’ve styled the paragraph straight, so the paragraph is styled the best way you’ve indicated,
somewhat than inheriting from the <physique>.

In case you then create a particular paragraph class – say, “legalese” – and declare that “legalese” is all the time 10px tall, the higher specificity of <p class=“legalese”> provides you with that 10px positive print cherished by authorized departments all over the place.

The extra particular rule wins out over the less-specific rule.

Within the wacky world of CSS, a content material div that seems within the <physique> is taken into account extra particular than a content material div declared by itself, despite the fact that they imply the identical factor. If IE5/Win may learn CSS2 syntax, it will do as the opposite browsers do, and this trick wouldn’t work.


So now we had a liquid format designed totally in lean, clear CSS. A format that will show correctly in any decently CSS-compliant browser, however was far too advanced for a 4.0 browser.

That’s the place the WaSP’s Browser Improve initiative kicked in. And the place Nameless Donor B had the sensible thought of utilizing iframes to cue customers of 4.0 and older browsers to the desirability of upgrading. Sadly, iframes usually are not supported in later variations of XHTML, so we later changed the iframes with OBJECT tags.

Sadly, textual content inside invisible OBJECT tags confirmed up in standards-compliant (however restricted) browsers and gadgets equivalent to Lynx and Palm Pilots™. So we added JavaScript to the OBJECT tags to cloak their content material from these browsers and gadgets.

Sadly, including JavaScript to the OBJECT tags induced IE5+/Home windows to cover the TITLE of net pages, and likewise induced IE5+/Home windows to report bogus safety alerts in some circumstances, relying on person safety settings.

Ultimately Nameless Donor A crafted fiendishly difficult (however completely standards-compliant) workarounds that will not louse up any browser. However by that time, we had surrendered. We’re now wrapping our “improve” message in a easy <P> tag, and utilizing CSS to cover that tag:

<p class=“ahem”>

This website will work and look higher in a browser that helps
net requirements, however it's accessible to any browser or Web machine.

How and why this works is defined on the WaSP’s developer ideas web page.


There was yet one more determination to make: whether or not or to not let 4.0 browser customers see the woeful method their browser botched the brand new model sheet. We determined to defend them from it.

There are lots of methods to do this, foremost amongst them JavaScript browser detection or server-side applied sciences. We determined to make use of HTML as a substitute. Fairly than hyperlink to our model sheet the standard method …

<hyperlink rel=StyleSheet href="https://alistapart.com/css/model.css" 
kind="textual content/css" media=display>

… we linked to it thusly:

<model kind="textual content/css" media="all">
@import "/nucss.css";

5.0+ browsers perceive that technique. 4.0 browsers don’t. Children, do this at house.

Through the use of the @import technique with double quotes, you defend 4.0 browsers from themselves, and have the liberty to make use of CSS because it was all the time meant for use. That is one other method of claiming you lastly have the liberty to make use of an online normal per spec, as a substitute of kludging and compromising it on the gate.

And for individuals who make web sites, that’s nothing in need of revolutionary.

Late within the recreation, we found that IE4.5/Macintosh understands the @import technique of linking to a mode sheet. It additionally, extremely, will get the field mannequin proper. But it surely doesn’t perceive CSS2 selectors.

So IE4.5/Mac shows the content materialdeclaration as written, per CSS1 spec. Sadly, the content materialdeclaration, as you might bear in mind from studying it a number of paragraphs in the past, was written utilizing bogus values to trick IE5.5/Home windows into displaying the format accurately. IE4.5 subsequently does an ideal job of displaying the improper declaration, and in that browser the format might be greater than a bit off.

And now the ultimate kink. After ALA was redesigned utilizing the strategies described on this article, the IE6 beta for Home windows was launched to the general public. Like IE5/Mac, it helps DOCTYPE switching. Like IE5/Mac, Opera 5, and the Gecko browsers, it will get the CSS field mannequin proper. In contrast to these browsers (however identical to IE4.5/Mac), it doesn’t acknowledge CSS2 selectors.

So, identical to IE4.5/Mac, the IE6 beta does an ideal job of displaying the improper declaration. The browser is true however the format is improper.

Fortuitously, we had solved this downside by ALA Challenge No. 100, which makes use of an easier model sheet and a wrapper DIV to carry all of the items collectively in any CSS-compliant browser.


Throughout the first week of April, net designers who use CSS, specialists who’ve helped create the CSS suggestions, and a standards-oriented browser developer, all participated in a casual group dialogue about the most effective methods to create CSS layouts that compensate for browser variations.

A lot of this has been summarized by participant Eric Costello, and many people netted out on utilizing a CSS field mannequin hack created by Tantek Çelik, growth lead for the Tasman rendering engine, and contributor to CSS2 and CSS-3. It appears scarier and extra advanced than it truly is.

The CSS strategies used at ALA since Challenge 100 are primarily based on a distinct strategy, they usually operate effectively in IE6 beta, IE5/Win, IE5.5/Win, IE5/Mac, Mozilla, Konqueror, Netscape 6, and Opera 5.


Changing HTML desk hack layouts with legitimate CSS is sweet for net customers, designers, and the medium’s stability and progress. The article you’ve simply learn, limitless although it might appear, barely scratches the floor. Since this text was first written, a number of positive assets have sprung up, together with:

  1. BlueRobot’s CSS Format Reservoir and CSS Centering mini-tutorials #1 and #2
  2. Glish’s CSS Format Methods
  3. Owen Briggs’s wonderful Little Packing containers visible layouts web page, and the Field Lesson Drawback & Workaround Set, which addresses bugs in numerous browsers.

The separation of favor from content material is at ALA immediately, however tomorrow, or the day after, will probably be in any respect websites. Removed from seeming revolutionary, tough, harmful, or non-user-friendly, it should merely be the best way the medium capabilities. It’s, in any case, the best way the online was all the time meant to work.

Those that consider the online primarily by way of graphic design might want to enlarge their views, however they received’t lose their expertise or their imaginative and prescient in doing so, and they’ll achieve tremendously in management and adaptability.

Possibly you’ll be a part of a few of us as we attempt to roll the rock uphill a bit quicker than typical person improve patterns dictate. Possibly you’ll sit again to see how the entire thing shakes out. However whether or not you select an activist position or a non-participatory one, now could be a superb time to start out studying how these requirements actually work, and the ability they’ll deliver to your websites.

Even should you select to maintain your CSS and different standards-based experiments offline, or share them solely with a choose few, the time to experiment and be taught is now. As a result of very, very quickly the entire net will work this manner. And also you’ll need to be a part of it – as a result of finally it’s a higher, less-frustrating, extra highly effective solution to construct web sites.

After all, should you select to not study CSS and different net requirements, MacDonald’s eating places are mentioned to have a wonderful administration coaching program.

We’ll see a few of you on the barricades, and the remaining one other mile up the street.
