Honoring Mobile OS Text Size If your users scale the text size in Android or iDeviceOS, that doesn’t always affect the size of text on a web page. It’s a function of browser and authored code, as opposed to a standardized approach. That may be changing. Support The current state of affairs in the three…

It’s a post now:

712 words, but the images are huge (dimensions, not file size). I also captured fresh images (last night’s were an old version of my demo).

There are so many people who take the time to really listen and care and do things well.

And then something like CSS carousels comes along and a11y folks end up spending their time and energy on damage control instead of their own a11y spec improvements.

A threat model for accessibility on the web - Alice A explanation of the primary threat to accessibility on the web, and a call to action for the web standards community

I feel this post deep in my bones, Alice gets right to the heart of why working on a11y in standards can feel like killing your soul by degrees.

And also why it’s hard to stop.

I’m so glad you liked it! It was such a weird experience going last, because I didn’t really get a chance to talk to other folks there about it.

Also you’d be a good pick yourself, and @sarasoueidan.com

It’s also pretty common to just invert the foreground/background tokens for a given control in forced colors.

All of which should provide an accessible approach to state changes, often better than not adding custom color styling.

Color changes that meet 3:1 contrast are not considered “color alone” by wcag.

While you can’t know the contrast of user-selected colors, I think it’s fair to assume they were selected because that user can perceive them.

To be more explicit, as long as this overrides OS-level user caret styles, this is a terrible idea, and really showcases what spec work looks like when a11y isn’t involved at all.

Adrian is wrong about exactly one thing in his post, which is that “when the caret is no longer a stick” is an *excellent* pun.

Added to this: in my experience running user tests with low vision users, customizing the caret is actually pretty common as an accessibility affordance.

To be fair, I only considered it because of all the bugs my team gets because of it 😅

It’s one of those fun instances of tension between writing the most accessible UX *now* vs. writing what will remain an accessible UX 😭

If it’s a bug then it might! I think the Edge team handles a lot of the forced colors issues, and they’re all lovely (my post isn’t a dig at them personally, these decisions are old).

The issue with backplate is it’s functioning as intended, so there’s nothing to fix from the browser’s POV

forced-color-adjust: none is an unavoidable foot gun | Sarah Higley A very long treatise on why text backplates were a bad idea. Most of the time.

For anyone who pays attention to high contrast / forced colors mode styles:

I wrote up an explanation of why forced-color-adjust: none is nearly unavoidable and how it sets up your codebase for downstream bugs:

Unfired clay mug with a light purple to green gradient, dark green thin leaves, and an upside down, belly up black tardigrade that somehow looks like it’s smiling

The same mug, from another angle. The handle is to the right and a side-facing tardigrade reaches toward and grasps one of the dark green plant tendrils

I don’t currently, but I’d be interested in case I do in the future!

This is so much fancier than a brush shoved into a pile of clay, which is where I still am 😅

Accessibility overlays are good for business (just not yours) Accessibility overlays are for suckers. But they are ruining the spirit and reputation of one of the best things about computers: personalization. So why do businesses love them?

I've been thinking about accessibility overlays and what it means for personalization quite a lot the past couple of years. I've drafted up some thoughts on it:

Screenshot of the iPhone confirmation screen to turn off Apple Intelligence in dark mode. After a block of white text telling you what you’ll miss out on, there is a medium gray button with nearly unreadable red text that says Turn Off Apple Intelligence. After that is an easily readable button with white text that says Cancel

A photo of an unfired clay jar about 8 inches high and 6 around with an abstract texture around the middle and a domed lid. On the lid is a cute little lizard wrapped around the dome, peering forward at you. Its tail curls up into a round handle for the lid.

A top view of the same ceramic jar, looking down at the lizard so you can see how its body is sculpted in more detail. Some blue plastic and paper towels are in the background.

I suppose my inaugural post should be about accessibility or something for bRaNdiNg, but I'm going with this lil guy instead:
