muting background tracks, potentially optimizing sound-output parameters for spoken words, etc.

Obviously it would be best if this were all part of a W3C standard, rather than a vendor-specific extension.ДЄnother thought: while most major platforms support a global flag the user can set to request high contrast visuals, and make its state available to user agents, has there ever been an equivalent flag by which the user could request high contrast audio (e.g. Magnifier: support for high contrast colour schemes and a new interface for touchscreen devices Sign-in settings: allows the user to select which built-in. It would be unfortunate if authors assume the names were to be taken literally.ДЄlso, while their example of changing background images would make sense in some documents, most background images should be hidden altogether when high contrast mode is detected. I eventually found my solution in Sarah Higley's excellent Quick Tips for High Contrast Mode.Interesting, although I wish they'd made the reserved words 'light-on-dark' and 'dark-on-light' instead of 'white-on-black' and 'black-on-white' to avoid promoting the widespread but erroneous impression that users with low vision use monochrome display settings. Media queries wouldn't cut it for this problem. Since then, the World Wide Web Consortium has published a working draft with the forced-colors and prefers-contrast media features, but these are still subject to change and don't yet enjoy wide browser support, if any. When my attempts to use it were made in vain, I found that it had been deprecated since 2018 and was super experimental to begin with. I stumbled upon the -ms-high-contrast media feature, with settings for when High Contrast Mode is enabled, when it's set to black-on-white, and when it's set to white-on-black. After all, prefers-color-scheme can be used in many browsers to detect system-level dark mode settings. My first thought was to check for media query options for High Contrast Mode. Background styles are consistently the first thing to go in High Contrast Mode, however, and so we were left with no visual focus indicators.ДЄnd so, the problem at hand: restore focus indicators for High Contrast Mode users, while ideally maintaining the focus styles I already had for most viewing modes. These new, custom styles largely depended on changing elements' backgrounds, such as hollowing out the navbar links. I had overridden the default focus indicators with outline: none, and replaced them with my own custom focus styles. This isn't High Contrast Mode's default behavior. Tabbing through my site in High Contrast Mode, however, revealed a severe lack of focus indicators.

This article, viewed on Firefox with Windows 10's High Contrast Black theme Supporting browsers Go to footnoteВ will override styles for backgrounds, borders, outlines, and more. That palette could either be one of the presets or a custom scheme. Windows High Contrast Mode, or WHCM, is an operating system-level setting that, when enabled, replaces the color schemes in supporting applications with a reduced palette. As I was building out this redesign, I decided to try something I, admittedly, should have been doing much earlier: testing the page in Windows High Contrast Mode.

While I've been quiet, I've been working on a complete overhaul of the blog, giving it a fresh coat of paint and leveraging a completely different stack. This is a quick and easy way to remove the outline for most viewing modes, while preserving it for Windows High Contrast Mode users. If you're overriding browsers' default focus styles with outline: none, consider using outline: 3px solid transparent instead.
