Subject: The WAVE reports "1x very low contrast"
No previous message | Next message →
Hello Everyone,
The WAVE reports "1x very low contrast" on every page in our Library's
website. The following URL is a sample page:
http://wave.webaim.org/report#/https://lib.d.umn.edu/about/excellence
Is there a way to determine where the WAVE thinks the error is located
on the page? No low contrast icon seems to be in code view.
Thank you.
Kind Regards,
Laura

Urgh, that seems to be an odd one...smells like a false positive.
I brute-forced this by opening devtools and looking in the DOM for the
"wave.webaim.org/img/contrast.png" image. It appears twice in the
page...once in the left-hand WAVE sidebar itself, and once...inside the
search button <svg> top right.

Looks like a false positive. None of the other tools I use reported a contrast issue.

Yep, it's a rather obscure false positive on the <title> within the
SVG. Chrome (at least) has recently changed the way that these
elements are styled, even though they are not visually rendered, thus
they are now within the scope of WAVE's contrast checking. We've had a
fix for this in place internally for a while (including our logic when
the WebAIM Million analysis was conducted), but I just pushed this fix
into production. You may need to refresh, but this will no longer be
flagged as a contrast error.
Thanks,
