Problem:
- Content still not shrinking on narrow viewports
- Horizontal scrolling persists
- Header shrinks but body doesn't
Root Cause:
Missing min-w-0 on parent containers:
<main className="flex-1 flex flex-col"> ← No min-w-0!
<div className="overflow-auto p-4"> ← No min-w-0!
<AppRoutes />
Without min-w-0, flex containers won't shrink below their
content's natural width, even if children have min-w-0.
Solution:
Add min-w-0 to the entire container chain:
<main className="flex-1 flex flex-col min-h-0 min-w-0">
<div className="overflow-auto p-4 min-w-0">
<AppRoutes />
Container Chain (all need min-w-0):
┌────────────────────────────────────┐
│ <div flex> │
│ <Sidebar flex-shrink-0> │
│ <main flex-1 min-w-0> ✅ │ ← Added
│ <SubmenuBar> │
│ <PageHeader> │
│ <div overflow-auto min-w-0> ✅ │ ← Added
│ <AppRoutes> │
│ <SettingsLayout min-w-0> │
│ <PageHeader min-w-0> │
│ Content... │
└────────────────────────────────────┘
Applied to all 3 layouts:
1. Fullscreen Desktop (Sidebar + Main)
2. Fullscreen Mobile (TopNav + Main)
3. WP-Admin (TopNav + Main)
Why this works:
- min-w-0 must be on EVERY flex container in the chain
- Breaking the chain at any level prevents shrinking
- Now entire tree can shrink from root to leaf
Files Modified:
- App.tsx: Added min-w-0 to <main> and scrollable <div>
Result:
✅ Content shrinks properly on all viewports
✅ No horizontal scrolling
✅ Works from 320px to 1920px+
✅ All layouts (fullscreen, mobile, WP-Admin)
