    That's nonsense. The accessible thing to do is not set a font-size at
    all. (If you want to change the appearance of a site, the accessible
    way to do so is to set body to 100%, and other elements relative to
    it. But you already knew that.)

      I'm sorry! I'm a consultant. I'll steal your watch then charge you if you want
      to know the time. I push people to the limit. And they do the same to me. (I
      maintain the FAQ for one NG and appear in another). I've got a lot of help
      here. I won't push my luck - someone may charge me!

      But I have now solved the problem of those 8 photograph-page CSSs. When I was
      replying to you, I suddenly had an idea about contextual selectors. (No, you
      can't charge me for it!) I've just tested the idea, and it works. I can get
      down to 1 CSS for those pages! Instead of saying:

      <link rel="stylesheet " href="style_dar k_grey.css" type="text/css">
      </head>
      <body>

      I can say:

      <link rel="stylesheet " href="style_one _css.css" type="text/css">
      </head>
      <body class="dark_gre y">

      So, I can have just the one "style_one_css. css" for all my photograph pages.
      Then I can say things like:

      body.dark_grey { background-color: #191919; background-image:
      url(../assets/dark_grey.gif); color: #C1C1C1; }

      body.dark_grey a:link, body.dark_grey a:visited { color: #4444FF;
      text-decoration: none; }
      body.dark_grey a:hover { color: #FF0000; text-decoration: none;
      background-color: #FFFFFF; }

      body.dark_grey div.middle, body.dark_grey div.inner { padding: 7px; border:
      solid #000000 1px; }
      body.dark_grey div.middle { border-left-color: #666666; border-top-color:
      #666666; }
      body.dark_grey div.inner { border-right-color: #666666; border-bottom-color:
      #666666; }

      Blindingly obvious to experts. A breakthrough to me. Control photograph-page
      colour and style via the body tag. (Hm! Should it be ID, not class?)

      I hope those have been taken into account in the W3C guidelines.

      But the real point is, getting the photograph on the right background is an
      order of magnitude more important to me than getting the text the right
      colour. (I used to use a pop-up window that only showed the photograph on a
      chosen background, no text at all).

      I accept the consequences if some people fundamentally disagree with my
      choices.

        I think the point here is what you feel should be included in the base
        price...if one assumes that the base cost for a site includes an ability
        to be adequately spidered and indexed by search engines then pretty much
        every accessibility issue is already dealt with...If you merely include
        the content being visible on the web to a small number of visual web
        browsers then there might be some additional costs...however I'd assume
        that ANYONE claiming to be a professional web designer would at the least
        be ensuring that Google can index the site as an essential basic part of
        the job

          And you would be right.

          Alan is quite capable of answering on his own, but if you got THAT response
          out of HIM, then the world would be two days dead allready.

          One of the reasons why accessibility is easier - and why cost does not
          spring into play - on the web is the fact that the framework is allready
          there.

          Have you ever read Greg Bear's "Eon" ? If not, it comes warmly recommended
          should you enjoy SF; and it has a few points that can be applied to this
          topic.

          IF the physical framework of a car - the steel - could adjust automatically
          to fit any size or type of chair, then such a hypothetical answer would
          be correct.

          Steel does not. The web does.

          That's peculiar, really. It's mostly those of us working with accessibility
          that are deemed "politicall y incorrect" ...

            Now I'm confused. It seems, from the URI you quote, that few builders are
            even able to quantify the additional costs.

            I've got some experience with building various gadgets. Granted, I did
            not personally build any liquid gas tankers ;) but it runs in the
            family.

            A construction company, typically, is slightly sloppy when it comes
            to costs. The typical priority is time - material simply doesn't cost
            as much as does people.

            And it's faster to build an accessible site. Much faster. Well, IMnsHO,
            naturally.

            It's the tinkering that gets expensive, really.

            "Oy, vey, we forgot to put in plumbling on this floor. Blast, where did
            we leave the concrete saw ? Overtime again, damned!"

            "Oh, no, we forgot to include skip-navigation links on all pages, we'll
            have to recode every single one!" (why didn't they use templates ?)

                I think the problem we're having with this discussion is that you're
                taking as your reference point the miniscule proportion of web sites
                such as your own where the groundwork was already done, the site has
                been composed by a serious practitioner according to rules of good
                practice, the basic accessibility features have already been catered
                for, and you're dealing with the extra cost of meeting additional
                issues that are raised by the guidelines. Whereas I'm bleating about
                the mass of websites produced with some unspeakable pretend-WYSIWYG
                website-extruding package, where IMNSHO the issues that I am raising
                are very real, and by no means "straw man" issues.

                Then I would have to agree. Car models appear to be designed with a
                relatively narrow 'use case' in mind (different models aimed at
                different use cases), and most of them don't include disability access
                in their use case.

                The web however was designed for diversity of access to information,
                and although the original motive may have been diversity of equipment
                rather than diversity of user, the fact is that for many kinds, at
                least of non-specialised content, it works that way regardless of the
                original motive, if the design task is approached flexibly.

                Exactly! In terms of the criteria that we are discussing, the
                majority of web sites _are_ broken, and IMHO that's the first priority
                for action. I don't wish to see a ghetto-ised web, with a tiny
                minority of sites accessible to disabilities to the n'th degree, while
                the rest - whether by intent or by neglect - remains implacably
                hostile.

                I agree. So let's at least encourage folks to make the start.

                To satisfy the full-blown array of guidelines at all levels is hard,
                indeed for some kinds of material it's impossible because, in the end,
                some of the guidelines become mutually contradictory. But that's no
                excuse for those who insist on inserting pointless "kewl feechers" and
                then proudly claiming that those features define their "target
                audience".

                  I think you have made a good point here, although I don't know whether I am
                  reading it the same as you.

                  If a site can be indexed by search engines, then it is "visitable" . That is
                  only a start, although a good one, to being accessible. It says that a dumb
                  engine with enough processing power can in principle navigate around the site.

                  But is it "livable"? Would a flesh & blood person draw the same conclusions
                  about the site as the search engine? Would a person tolerate what the search
                  engine will tolerate?

                  Perhaps "indexabili ty" is "level 0" of accessibility?

                    in most respects one has to treat a search engine spider as a blind, deaf,
                    but determined moron using an extremely stripped down and rare web
                    browser...so in terms of navigation one is dealing with an extreme case of
                    accessibility.. .in terms of the content though one looks more at the
                    searcher than at the bot...it's all about placing important content where
                    it is easy to get at and ensuring that everything is easily understood

                    by the time a site is competently set up for the search engines one would
                    have to put in some serious extra effort to make it inaccessible

                    sadly the normal design process is to make a totally broken and
                    inaccessible site and then spend large sums of money on an SEO to fix it

                      I think we understand one-another and pretty well agree.

                      And I run with Flash animation, GIF animation, ActiveX dialogues, and

                      "kewl feechers"!

                        Rather than debate terminology, I'll give you a demonstration of using
                        W3C-conformant CSS to add a border to a photograph before turning it into a
                        JPEG. I hope that you will then see that, for inherently visual material, the
                        split between content & presentation is forever blurred.

                        Here is the original JPEG, which has been on the web for some time:



                        Here is basically the same photograph, also a JPEG, to which I have added a
                        border using W3C-conformant CSS. (I'll tell you how, including the CSS itself,
                        later). Here is a URL to the JPEG, and a URL to a HTML document that
                        identifies the JPEG as its content





                        Here is the extract from the stylesheet that I used to put the border into the
                        JPEG. This was obviously presentation when I added the border:

                        body { background-image: url(eggshell.gi f); }
                        div.middle, div.inner { padding: 7px; border: solid #554433 1px; }
                        div.middle { border-left-color: #FFF7EE; border-top-color: #FFF7EE; }
                        div.inner { border-right-color: #FFF7EE; border-bottom-color: #FFF7EE; }

                        Here is the URL of the "eggshell.g if" used:



                        Now: given that I used the above CSS to add the border to the original
                        photograph, isn't that border presentation? Yet above is a JPEG with that
                        border inside it. So I guess you would call it content.

                        I expect you know how I used W3C-conformant CSS to do simple photo-editing,
                        before creating the JPEG. You have the tools on your computer too.

                        In case there is anyone reading this who doesn't know, I started with the
                        photograph page below, in which the original photograph is identified by the
                        HTML, and the border is added by the CSS (of which the above is an extract):



                        I then did screen capture, and fed the results into a bog-standard
                        photo-editor to crop it and turn it into a JPEG. I didn't waste time on it (it
                        just tooks minutes). So I could get much better quality if I wanted to. (For
                        example, it is double-compressed).

                        What does this show? In a very narrow sense of just the use of HTML/CSS at the
                        very last stage, it is possible to decide what to call content and what to
                        call presentation. But in the total photographic process, genuine
                        presentation, as understood by this NG and others, can also be seen as genuine
                        content, as understood by this NG and others. After all - I did web authoring
                        with HTML/CSS at 2 different places in the process.

                        That is why, while I understand the narrow use of the words that some may use,
                        I see the entire process of photography as adding presentation by various
                        technologies and standards. There is nothing special about the last stage,
                        except simply that it IS the last stage, and can therefore still be
                        manipulated in ways that earlier results cannot. People who work with
                        inherently visual material can make decisions about where certain presentation
                        is added - before, during, or after the final HTML.

                          But, getting back to the cost point, my experience in the industry is
                          that in general code of solid quality (and this seems to be what you
                          are talking about) costs -- initially at least -- more.

                          I'm not a frontend designer and usually am more concerned with stuff
                          that's not visible, but I guess the issues are the same. It is cheaper
                          to get a simple site up, done by somebody who has barely mastered the
                          most important menu options of a web site design tool, than to hire
                          one of the experienced designers. So, from the point of view of the
                          owner of that site, she got 10 pages that work for her. They are
                          crappy HTML and if they use CSS at all it's possibly even worse, they
                          are not "accessible ", but to have them done with a solid, designed
                          structure could easily have cost multiples of what she paid for them.

                          I think the analogy is broken here. A car would correspond to a site,
                          not the web, and the web would correspond to all the cars (and the
                          Internet to the roads and streets). This then becomes that the roads
                          accomodate all kinds of cars with their individually narrow use cases,
                          just as the web consists of all kinds of sites with more or less
                          narrow (possibly "non-accessible") use cases.

                          I didn't feel that anybody in this discussion wouldn't agree with you
                          on this. (I certainly do, even though Barry wrote pretty much what I
                          think, too.) But I don't think it comes for free. From the point of a
                          web site customer, this costs extra. I'm sure you charge more than a
                          high-school grad who knows a bit about Dreamweaver or whatever the
                          site generation tool is she uses.

                          I certainly do, and I know that I won't churn out simple VB apps for
                          the price some of the programmers out there do. I tend to think that I
                          produce better quality code than some of them, but I have my price --
                          and most everybody who does has.

                          This point is very much philosophical, I think. I don't see a
                          technical question here, and no budgetary question either. It is about
                          whether this is a "good" thing. Some people sure think it is. I don't
                          think that by alienating them you make a huge impact. In terms of
                          convincing people and educating them about pros and cons of what they
                          do it is usually much more efficient to work with them rather than
                          against them (unless you envision hard legal rules about what has to
                          be done and what must not be done). I don't see that happen a lot.

                            You're making the common error of comparing initial purchase prices without
                            taking total cost into account. Lots of bad deals look good when you do
                            that. A quality expert (I think it was W. Edwards Deming) told a story
                            about a shoe manufacturer who "saved" money by buying cheaper thread than
                            he had been previously using. Sure, there was a saving on the line item
                            for thread. But the cheap thread broke frequently, forcing the stitching
                            machines to halt while the operator rethreaded them. The rethreading took
                            so much time that the manufacturer had to run the factory on overtime in
                            order to meet his production requirements. The extra cost of the overtime
                            more than completely wiped out the savings on the thread.

                            You say "she got 10 pages that work for her." What does that mean?
                            Assuming the site is supposed to promote or even conduct her business, it
                            matters not one whit how well it works for *her*. What matters is how it
                            works for her *customers*. Businesses make money by impressing their
                            customers, not by impressing their own management. The days are long gone
                            when a commercial Web site was simply a matter of marking territory on the
                            Web. If the site has to be reworked to make it useful to her customers,
                            then the cost of the rework has to be taken into account. You can't
                            pretend it doesn't exist. And if the rework isn't done, then the initial
                            money paid was *completely wasted*; the owner would have been better off
                            not spending it at all.

                              Sadly, I have to agree. Some sites defy both human navigation and search
                              engine navigation.

                              What we both appear to believe is that search engines and accessibility
                              principles are actually compatible with one-another. A search engine can't
                              just take "a bird's eye view" of a site or a page. Neither can a blind person.
                              Both rely on a certain amount of structure. Both tend to need a considerable
                              amount of serial processing of the material.

                              I wonder how much advocates of accessibility promote the idea that sites that
                              are accessible to (say) blind or physically handicapped people are probably
                              going to be accessible to search engines too? Perhaps they advocate it a lot,
                              and I've missed it. But at a basic level, it is true. And if you can answer
                              the site developer's question WIFM ("what's in it for me?") you are half-way
                              there.

                              If I had one wish to cater for both causes, I would say: "provide a properly
                              structured site-map accessible from pretty well every page". A site map is
                              often what stops me walking away from a site for ever.

                                You missed the point. I was talking about what I see in my own controlled
                                environment (see my words), and I control that. THEN I publish the material,
                                and I confidently expect that sorting things out in my own environment will
                                greatly improve the perception of my published material in other environments.

                                I try to achieve very similar results in a useful set of browsers (with
                                default settings) on my PC before I upload. I take the trouble to understand
                                any differences, and where possible reduce or eliminate the differences using
                                W3C-compliant CSS. As a result, I have confidence that a majority of people in
                                the world using those browers will see similar results to what I see. Since
                                the CSS is W3C-compliant, I can expect that many future browsers, or
                                brower-versions, will also show my published work in a very similar way, if
                                they are used on their default settings.

                                I also expect this to improve over time. We are currently going through a
                                transition phase, where many users haven't reached the 21st century yet. That
                                is a temporary situation. Perhaps, in 10 years time, 99% (choose your own
                                number) of users who are browsing according to "media type = screen" will be
                                using user agents that conform to CSS2. Perhaps (choose your own number) 80%
                                or 90% will be using user agents conforming to CSS3. This will enable us to
                                vastly reduce, and typically eliminate, the rendering differences between just
                                about all the common browsers at their default settings, if we choose to.

                                At the moment, we are lucky if most browsers support HTML properly! As the
                                years go by, daft browers will become irrelevant and new ones will be far
                                better. CSS1, then CSS2, then CSS3 will in turn become rendered in vastly more
                                consistent ways. People will publish valid CSS rules for eliminating the
                                remaining differences, for example to eliminate differences in defaults. (I
                                currently need CSS2 to eliminate certain peculiarities in Mozilla Firebird,
                                and CSS3 to eliminate others. I use the former because W3C validates it. I
                                don't do the latter because it doesn't. In a few years time, W3C will validate
                                CSS3, I will make the changes to my CSSs, and Mozilla Firebird with its
                                default settings will render my pages like other user agents do).

                                We are moving towards a world where people who care will be able to ensure
                                that just about all the common browsers, used at their default setting for
                                media type = screen, will render their material in pretty much an identical
                                way. And this will only need validated HTML and validated CSS - no frigs or
                                hacks. Let's continue the discussion in 2013!

                                Perhaps you mean:
                                The Web Design Group's Feature Article, by Alan Flavell, discusses the proper use of ALT texts in IMGs.


                                I started the above thread about this:
                                http://groups.google.c om/groups?as_umsgi d=fpE3b.80$b82. 83115@newsfep1-win.server.ntli .net

                                Alan Flavell and many others contributed a lot. I read the above page quite
                                early on. With respect to Alan, it is a little bit out of date, and doesn't
                                really say "if you are a photographer producing thumbnail gallery, do this". I
                                want to write something that starts with what to do in specific circumstances,
                                and link to why. In other words, a process-oriented view.

                                For example, here is a reply to someone else:
                                http://groups.google.c om/groups?as_umsgi d=FfJ5b.4487$Ci 1.663381@newsfe p2-win.server.ntli .net

                                I'm a competent IT person. I've snipped the obvious advice, while recognising
                                that it would be valuable for novices.
