You Want Mobile Dreamwidth, Artie? You Got It.
Coexistence Alpha: a mobile-friendly CSS patchset for Neutral Good - v0.846 RELEASE CANDIDATE TWO
(2019/2/6)This is a fully-responsive mobile-ready theme modification layer intended to make Dreamwidth's default style fully functional on both mobile and desktop devices wherever it can be applied. Features include journal and reading pages with near-zero horizon scrolling on mobile, including in long comment reply cascades, and more-comfortable comment creation, including on iOS.
To install: Choose style "Neutral Good" for "Practicality" in the journal style selector. Copypasta all of the linked CSS into the Advanced Seettings Custom CSS box, and save. (This may require a desktop device.) Apply "your style" to everything you can.
This build includes Navbar 2, which is mostly cosmetic but somewhat mobile-aware upgrade of the Navbar.
