## Original Query
Hi, is anyone working on this page looking normal?
http://zenmemes.com/compose/thread
iPhone SE3 Firefox
## Understood Intent
Make the New post page, and by extension the rest of the phone layout, look right on a 375px-wide iPhone in every theme. The repro in my previous reply found two failures. In Word 97 and Midnight, the desktop window chrome and status bar spill past the screen edge and the background leaves white gutters. In Sticker and Arena, the Post button starts under the bottom tab bar. The default theme looked fine logged out, so the reporter's exact theme and login state are still open.
## Problem statement
Themes draw their own chrome without knowing about the phone tab bar and the 375px width, so some themes break the phone layout.
## Concepts touched
- Theme (proposed entry): changed under all options.
- App shell / bottom tab bar (proposed entry): used unchanged in A and C, changed in B.
- Compose form (proposed entry): changed (bottom clearance) in A and B.
- Theme regression check (proposed, new): created in the add-on.
## Option A: Patch the affected themes
Add phone rules inside the Word 97 family stylesheets and the Sticker and Arena stylesheets. Under 640px: hide or shrink the status bar, fit the window frame inside the gutters, stretch the title bar, paint the background on html, and give the compose form extra bottom padding where those themes have thick borders and shadows.
- Pro: smallest change, fixes exactly what was measured, no risk to the other 9 themes.
- Pro: can ship tonight.
- Con: the next theme with chrome can break the same way; each theme author has to remember the phone case.
- Con: the bottom padding fix gets copied per theme.
## Option B: Give themes a phone layout contract in site.css
Move the rules into the shared shell. Themes declare their extra chrome through a few CSS variables (for example bottom chrome height and frame inset), and the shell adds them to --app-tabbar-offset. Desktop-only chrome such as the status bar gets a shared class that the shell hides under 640px. Themes keep their look and stop owning phone layout.
- Pro: fixes the class of bug, not the instance; a new theme only fills in the variables.
- Pro: one place to reason about the tab bar, which already has hidden and shown states.
- Con: touches the shell and all 13 themes at least lightly, so it needs a check across every theme.
- Con: picking the variable names takes some design.
## Option C: Drop decorative chrome on phones
Under 640px, every theme falls back to its colors and fonts only: no window frames, status bars, or heavy shadows.
- Pro: simplest rule to state and keep.
- Con: Word 97 and Midnight lose most of what makes them themes on the device people use most.
- Con: doesn't fix the Sticker and Arena padding on its own.
## Add-on (works with any option): theme regression check
A short headless WebKit script that loads key pages at 375 x 667 in each theme and fails if scrollWidth exceeds the viewport, any element runs past the right edge, or the Post button sits under the tab bar. I used this to get the numbers in the bug report.
## Recommendation
Option B plus the regression check, with Option A's specific fixes used as the first test cases. Vertical slice: the compose page in Word 97 on a 375px viewport. It covers the status bar, frame, background, and tab bar offset in one screen, then Sticker and Arena prove the offset variable works for a second kind of chrome. If time is short tonight, A is a fine stopgap as long as it doesn't block B.
Before Step 2: confirm which theme you were on and whether you were logged in, in case there's a third failure I didn't reproduce.
## Enhancement Requests
None yet.
