Hi,

Firstly I commend you for the initiative.

I'm a website developer looking at your samples for better insight on WCAG.

I'm looking at https://www.w3.org/WAI/demos/bad/after/survey.html


My problem is the page is failing automated tests.

http://achecker.ca/checker/index.php 70 known problems

68 of the “known problems” seem to be the red color of links. The color (#ba2710) is tested against the background color of the body element (#555753). If we would use the links directly on that color, that would indeed fail WCAG2.0 but the link color is always used against white or other suitable colors, which meet the contrast ratio<http://leaverou.github.io/contrast-ratio/#%23ba2710-on-white> just fine.

The first error (<input type="submit" alt="submit" value="submit">) looks like a copy & paste error, and while it is not optimal it should not create problems with assistive technologies. I have noted the error and we will correct it with the next update.

http://wave.webaim.org/report#/https://www.w3.org/WAI/demos/bad/after/survey.html 1 error

Both tests show errors for the empty th element in the top-left of the table, and while a td would be more appropriate, it should not cause confusion in practice. We will take the feedback in condideration for the next update.

For more information on best practices, find the tables tutorial here:

https://www.w3.org/WAI/tutorials/tables/


and the example with two headers specifically here:

https://www.w3.org/WAI/tutorials/tables/two-headers/


Note that I'm not endorsing either of the tools. I just use them as a starting point for testing.

For more information on evaluation tools, see “Selecting Web Accessibility Evaluation Tools”<https://www.w3.org/WAI/eval/selectingtools.html>. We also have a list of evaluation tools<https://www.w3.org/WAI/ER/tools/> that allows you to search for an evaluation tool that suits your needs.

Best, Eric

Thanks,
Arthur
