What is the WAVE Tool?
The WAVE tool checks the accessibility of web documents. You simply add the URL of the print version of a guide and it'll check through the whole thing, reporting back any errors or alerts.
Getting the print version of your guide: Click the Print Guide icon in the top portion of the page.
Copy the URL in the address bar and go to the WAVE tool to get an accessibility report.
Most times, the errors reported back are missing ALT tags on images, which is easily remedied! Just edit the image and add a description in the Image Description field. Once you save the box, that error message is taken care of. It can be as simple as that.
I ran the print version one of my guides through the WAVE tool and it passed with flying colors! At least, it passed without any major errors. ;)
As the report states, it "detected no accessibility errors, but you must still check the page to ensure it is actually accessible". There were a couple of places where there was an alert that a bold tag as using b instead of strong. As soon as I changed those, the alerts went away.
The only other alerts were telling me that a link opened in a new window instead of the same window, which can cause screen readers & the folks using them some confusion. They might not be able to get back to the original page/window...at least not easily.
So after fixing the errors WAVE may tell you about, it's worth looking through the rest of the report to fix/change some things in your guide so that you know the content you added is accessible. :)
