    Is there a way for a web page to query whether increased contrast is turned on at the OS level?

    I think the answer is no, but if there’s a way in the W3C works, I figure Fedi knows.

      UPDATES:

      1. My site (https://innig.net/) now offers high-contrast theme if the OS / browser is set to high contrast mode. Works in both light and dark mode! Further accessibility improvements to come.

      2. Many online accessibility checkers apparently audit text contrast without actually applying `prefers-contrast: more` to the stylesheet. This seems…broken?

      3. Sa11y is a really great tool: https://sa11y.netlify.app It’s a live, in-page accessibility audit whose workflow is far, far more useful for actually improving the page than the server-based “enter your URL” online services. Killer features:

      - It live-highlights potential issues on the page.

      - It lets you dismiss warnings and •remembers that you dismissed them•, so it can offer subjective concerns that require manual review (e.g. “this image is marked as decorative; is that correct?”).

      - Per the previous post, it actually respects the contrast setting, because it reports on what’s on the screen.

      @Steve
      There can’t be an •equivalent• exactly, because Sa11y is Javascript that runs inside the web page, and there is no such thing for PDFs. But I know there are PDF accessibility auditing tools out there! (I have no experience with them.)

      @inthehands Is there an equivalent to evaluate accessibility of PDFs?

      @corvus
      Using it for my personal site now, but I’ll also shortly be using it on the site for a fall course site that I hope can double as a public open education resource.

      This looks great. Currently working through a course on Open Educational Resources and accessibility is an essential part of the process. One of the webpages I manage has already been audited for AODA compliance so it will be good to see what a different assessment tool says.
