Guideline 10. Use interim solutions.
Section 508, (Technical Standards) 1194.22
http://www.w3.org/TR/WCAG10/#gl-interim-accessibility
"Use interim accessibility solutions so that assistive technologies and older browsers will operate correctly."
10.1 Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the user.
10.2 Until user agents support explicit associations between labels and form controls, for all form controls with implicitly associated labels, ensure that the label is properly positioned.
10.3 Until user agents (including assistive technologies) render side-by-side text correctly, provide a linear text alternative (on the current page or some other) for all tables that lay out text in parallel, word-wrapped columns.
10.4 Until user agents handle empty controls correctly, include default, place-holding characters in edit boxes and text areas.
10.5 Until user agents (including assistive technologies) render adjacent links distinctly, include non-link, printable characters (surrounded by spaces) between adjacent links.
Once again, the things we are currently working on in class are directly tied in with what the WCAG teaches us. For our class Acme site, we created a link that when the thumbnail picture was clicked upon, it would either pop up a new window with a larger view of the image, or if the browser does not support javascript, then it would move us to a new page showing the larger image (not a pop-up). We also follow the guideline by informing the user that they will be taken to a new page with the larger image. They then know that the current window will be replaced with the full-size image. They can then use the browsers' "Back" button to navigate back to the previous page.
We have also addressed 10.2 by aligning our forms and ensuring that they have proper ids and titles. We used CSS to line up all for titles and fields so that it has a organized look to it and because of the tab-index it will be read in order by screen readers also.
The main concept of this guideline, is that you should use WCAG when designing your sites. By making your pages XHTML strict, and by using CSS for layout, you can easily determine if your pages meet the current standards. Simple plugins to your browser have automated this process. If you familiarize yourself with the current guidelines, you might not have to make any changes at all to your finished pages. The goal should be to design it right the first time. This way, you will not waste time back-tracking to fix the pages that should have been created correctly in the first place. Increase your profits and don't waste time.
