Agenda Review & Announcements

janina: Matthew is in France for the advisory commitee meeting, representing us.

[APA recharter][(https://raw.githack.com/w3c/apa/charter-2025/charter.html)

Roy_Ruoxi: W3C review process may take around 3 months. We should process quickly. Let us know if anyone has concerns, here or by email.

janina: we should not be surprised if we receive questions on the process, so we should make sure we are in time to proceed and don't end up with a no charter period. It's procedural but important.

New WAI-IG Charter

<Roy_Ruoxi> WAI-IG Charter

janina: probably the busiest email list of W3C. An important charter to review for us. Only two weeks for us to review. We don't need a formal consensus.

Spec review requests

Audio Session

<Roy_Ruoxi> - issue: w3c/a11y-request#108

<Roy_Ruoxi> - tracking: https://www.w3.org/TR/audio-session/

Roy_Ruoxi: its a define effort for api surfacing audio. Various accessibility usecases here. This is working draft, no timeline for us.

janina: we want to make sure the screen reader is considered here. You should be able to specify which device receive which audio if you have severals.

Comment review requests

 Popover and dialog elements with lots of content can be inaccessible

<Roy_Ruoxi> - issue: whatwg/html#11176

Eric_hind: I'll take a look at it.

PaulG: the issue is on making things scrollable. It came from csswg.

CSS Update (Paul)

<PaulG> w3c/csswg-drafts#11396 (comment)

PaulG: there is a discussion about reading flow. Source order, Reading Order.

gautierchomel: On EPUB working group we have a challenge regarding images in different color modes. reading systems usually ignore authored CSS media queries targeting dark mode. Reading systems may use dark mode for their interface, but the reading windows offer many more theme options. It highlighted that dark mode, as defined, cannot solve the problem of transparent images disappearing when dark themes are used on reading systems.

PaulG: There are several options offered by CSS or SVG or other turnarounds to achieve something.

<PaulG> the ways to work around this issue that I'm aware of are author-controlled: use an SVG (fillColor, filter functions, system color tokens, etc), use filter functions with a PNG (ex https://bdwm.be/css-change-a-transparent-png-to-any-color-you-want/), put an outline on the shape that matches the original bg color but will contrast with the alternate,

<PaulG> provide media queries that swap images/backgrounds.

gautierchomel: here is the EPUB discussion w3c/epub-specs#2700

PaulG: it would need to dig more deeplky into the EPUB world.

janina: it sounds like a profile discussion

<PaulG> https://developer.mozilla.org/en-US/docs/Web/CSS/system-color

PaulG: I feel a way is to match color text

PaulG: with CSS variable

gautierchomel: I'll try that path and report here.
