Web Accessibility – Why Bother?
by Andrew Gray

You may remember the article "Is Your Website Accessible?" by my colleague David Gilroy which appeared in the July/August 2004 issue of this newsletter (see www.venables.co.uk/n0407accessibility.htm). This time, we are providing two new articles - one general and one more detailed. This first article tries to provide succinct answers to some commonly asked questions; the more detailed article, by David Gilroy, is described at the end of this one.

Why should I care about accessibility?

Believe it or not there are over 10 million adults in Britain covered by the Disability Discrimination Act (1995) - you can’t afford to ignore this issue for ever and get away with it! Hopefully you support the moral argument in favour of accessibility for all but if not then there are sound marketing reasons to be as inclusive as possible (why irritate or partially exclude 10m people?). But there’s a third less obvious reason why paying attention to accessibility issues makes sense. If you build your website to be accessible then it will work better on the new generation of internet devices (Blackberrys, smart phones, PDAs etc.). Many of the issues that make websites inaccessible to disabled users turn out to be the same issues that make them difficult to present on small screen devices.

Is text resizability necessary - and sufficient?

Why would you build a website and force all your users to view it at a particular font size? It’s crazy! You don’t know how young their eyes are or how good their monitor is or even what device they are using (don’t assume it’s a PC it could be smart phone). Furthermore, it’s easy to build websites in such as way that the user can select their own font size. On accessible sites you will often see a menu option that allows you to increase the font size. Is it sufficient just to provide text resizability? Certainly not – there are many other issues to consider.

What about completely blind people?

Blind people are often very avid users of technology and a significant proportion of them will already be in the habit of using special “screen reading” software. The software is basically a browser (similar to Internet Explorer or Firefox). It retrieves a web page, processes it to extract all the useful text and then starts to read the text to the user. As soon as you stop to think about how your webpages might “sound” when read in this way there are some obvious issues.

The biggest issue is probably the order of things on the page. If your page uses tables to control how content is presented on the page then the screen reading software will have a hard time. Should it read across the row or down the columns? How does it know? Does the page make any sense if the software reads the rows when the information is actually presented in columns (or vice versa)?

The answer is not to use tables to control the layout of pages. For many years now there has been a much better way of controlling page layout – a technology called Cascading Style Sheets (CSS).

What is CSS?

Cascading Style Sheets (CSS) is an international standard for controlling the presentation of information. In the old days the way a page looked and what it contained would all be jumbled up together. But for years now all good websites have been built in a way that keeps “presentation” (the way the page looks) separate from “content” (what the page contains). There are numerous benefits from this approach the most obviously of which is that you can change your mind about design issues without having to edit every page of content. You decide that headings should be red not blue? No problem! A small change to the style sheet and all the pages on your website will be affected. It’s just like a well design Word template – if you know even the basics about Word then you know not to apply font size to text in order to make it appear as a heading. Rather you should apply a heading style to the text and then modify the style sheet to control how headings appear.

The other main benefit of building websites with CSS is that they become accessible to a much larger range of internet devices…as well as to disabled users. A blind person using screen reader software will understand your pages far more easily since the content is clearly presented and signposted: “this is the content – read me” and “here is the presentation information”. But a fully sighted user with a Blackberry or smart phone will also benefit.

How accessible is accessible?

The Disability Discrimination Act (1995) does not specify exactly how websites must be built in order to be compliant. Instead the act (very wisely in such a fast moving technical environment as the Internet) talks in terms of best practice and suggests that you’ll face prosecution only if you fail to do what you reasonably can to make your site accessible.

In my opinion, the absolute minimum you need to do is to ensure that your website is built using CSS so that fancy layouts no longer hinder accessibility for disabled users. You may find that your developer has not implemented the standards 100% but provided you have a CSS based site any accessibility problems that are brought to your attention will be relatively easy to correct.

Who sets the standards?

The most important organisation for Internet technologies is an industry body called the World Wide Web consortium www.w3.org. To tackle the issue of accessibility they formed a project called the “Web Accessibility Initiative” which has developed a number of technologies and guidelines in this field. Read more about these at www.w3.org/WAI/.

Do most sites comply with DDA requirements?

Unfortunately not - most don’t even come close. Most were built 3+ years ago and are not using CSS technology (even though it was available at that time).

Will non compliant sites be prosecuted?

Probably not – not for now anyway. The important thing is to make sure that when you do next have your website designed, it is done properly. The existence of the legislation is having the desired effect in that most large websites are now built with accessibility in mind. There are so many good technical reasons to use the standards associated with accessibility that compulsion via high-profile persecutions seem unlikely (at least for now).

My colleague David Gilroy has written a very detailed paper for the newsletter entitled Ensuring your Website is DDA Compliant which looks at each of the requirements in turn and gives some practical advice about how to satisfy them.
