Hiya! This post is largely unnecessary here, as the admins have already enabled it, but since this has now gone live to all communities to opt-in, I figured I'd let everyone know what's going on with mobile theming.
So what is it? This means that the following values set in the Theme Designer will appear both on desktop and mobile:
Community background color
Sticky nav background color
Community header color
Accent color
Link color
Article background color
Background image (when selected)
Heading font
How does it work? Admins will receive a message prompt to check out Special:ThemeDesigner and review the wiki's theming for contrast issues. Once there are no contrast issues anymore, they can enable mobile theming for the community. Note that it is as of now no longer possible to make theming changes without fixing these contrast issues.
To facilitate color choices that work on both themes, the theme designer has also been upgraded to include a mobile preview!
So, if you're active on other wikis where you'd like this to happe, how to enable mobile theming?
