Here are some tips for effectively understanding and implementing accessibility strategies.
There is no wake up call like viewing a Web page you have developed on a screen reader to understand the issues that visually impaired users might face. This is also true for using the Internet with a grayscale monitor, a small screen, no audio, slow bandwidth connection or other less than ideal conditions.
A testing strategy should include a standards verification report, checking to see how the site appears with images and CSS disabled, a color contrast check and an audit of content with
In addition any plugins, applications and web apps should be checked to ensure that they work with a screen reader (including login and navigation). Even if the plugin itself cannot be used, it may be possible to present the content or function within an alternate tool/format.
There are very few accessibility requirements which can be blindly applied without considering the context of the Web page. For a screen reader audience in particular, a balance between too little information and too much redundancy should be maintained.
Some of the newer accessibility tags and standards have been proposed, but do not have full support yet in screen readers or broswers. Before spending great time and effort implementing new tags, make sure that modern browsers and screen readers such as Jaws have implemented them recently. Otherwise, it may be more efficient to use some other accessibility strategy.
For instance screen readers may not support all the tags for complex tables. In that case, a series of simple tables may be more accessible to more users.
Some tags and recommendations are time consuming to implement, especially if a Web site needs to be retro-fitted for accessibility. However, having developers experience screen readers may give them a different perspective.
Accessibility is, unfortunately, a complex issue which does not always lend itself to simple answers. You may hear conflicting advice on how to best implement accessibility. Understanding the audience issues and your goals will hopefully provide you with sensible alternatives.
Evan after implementing all the recommended tags and strategies, some users may still encounter problems you were not aware of, either because of unique conditions or outdated browsers or equipment. These users still need accommodation.
Screen readers and browsers are continuously evolving. Old problems may be solved and new ones created. Evolving technologies will create new accessibility issues.
BUT, if you incorporate accessibility now, you will be better prepared for new developments in the future and less likely to need to make major changes.
