# Mobile Responsiveness Fix Plan (320-430px)
## Overview
At viewport widths 320-430px, the dashboard is broken: sidebar rail steals 64px, padding steals 40px, leaving only 216-326px for content. This plan fixes all issues in priority order, grouped by file.
---
## Phase 1: Sidebar → Bottom Nav Bar (Critical)
### 1A. Add `xxs` breakpoint to Tailwind (`tailwind.config.js`)
**What:** Add a new breakpoint `xxs: '360px'` below the existing `xs: 480px`.
**Why:** Enables Tailwind utility classes for sub-480px styling. Also useful for font/spacing adjustments.
```js
screens: {
'xxs': '360px', // NEW
'xs': '480px',
...
}
```
### 1B. Create `MobileBottomNav` component (`src/components/MobileBottomNav.tsx`)
**What:** New component that renders a bottom navigation bar at viewports <600px.
**Collapsed state (default):**
- Fixed to bottom edge, 56px tall, full width
- Background: `var(--sidebar-bg)` with top border `var(--border)`
- Contains: 3 nav icons (Overview, Experience, Skills) + hamburger/menu icon for drawer
- Icons from existing `navSections` in Sidebar.tsx (reuse `UserRound`, `Workflow`, `Wrench`)
- Active state: teal accent color, same as sidebar
- Touch targets: each icon button is 44x44px minimum
**Expanded state (drawer):**
- Triggered by tapping hamburger icon or swiping up
- Slides up from bottom using Framer Motion `AnimatePresence` + `motion.div`
- Max height: 70vh, scrollable
- Contains: full sidebar content (patient name, details, search, tags, alerts)
- Extract shared content rendering from `Sidebar.tsx` into reusable pieces
- Backdrop overlay: same `rgba(26,43,42,0.28)` as current sidebar
- Close: tap backdrop, tap close button, or swipe down
**Implementation:**
- Use `window.matchMedia('(max-width: 599px)')` to detect mobile
- Accept same props as Sidebar: `activeSection`, `onNavigate`, `onSearchClick`
- Do NOT import from Sidebar — reuse the same data sources (`navSections`, `patient`, `tags`, `alerts`)
### 1C. Modify `Sidebar.tsx`
**What:** Hide the sidebar completely at <600px.
**How:** Add a `useMediaQuery` check or pass an `isMobileNav` prop. When viewport is <600px, return `null` (render nothing). The sidebar rail and overlay are replaced by `MobileBottomNav`.
**Important:** All existing sidebar behavior at >=600px must remain unchanged.
### 1D. Modify `DashboardLayout.tsx`
**What:** Integrate MobileBottomNav and adjust main content area.
**Changes:**
1. Import and render `<MobileBottomNav>` alongside sidebar
2. Add CSS class or style for bottom padding on main content when bottom nav is visible: `paddingBottom: 'calc(56px + env(safe-area-inset-bottom))'`
3. The `dashboard-main` margin-left should be 0 at <600px (since sidebar is hidden)
### 1E. Modify `src/index.css`
**What:** Override `dashboard-main` margin-left at <600px.
```css
@media (max-width: 599px) {
.dashboard-main {
margin-left: 0;
}
}
```
---
## Phase 2: Spacing & Padding Reduction (Critical)
### 2A. Reduce main content padding at small viewports (`DashboardLayout.tsx`)
**What:** Change padding from `p-5` (20px) to a smaller value at <480px.
**How:** Update className: `p-3 xs:p-5 pb-10 md:p-7 md:pb-12 lg:px-8 lg:pt-7 lg:pb-12`
This gives 12px padding at <480px instead of 20px, recovering 16px of usable width.
### 2B. Reduce Card padding at small viewports (`Card.tsx`)
**What:** Reduce `padding: '24px'` to 16px at small viewports.
**How:** Use inline responsive logic or a CSS class. Since Card uses inline styles, detect viewport width or add a CSS class:
Option: Add `className="card-base"` and define:
```css
.card-base { padding: 24px; }
@media (max-width: 479px) {
.card-base { padding: 16px !important; }
}
```
Or use a custom hook for viewport width and adjust inline.
### 2C. Reduce `chronology-item` padding (`index.css`)
**What:** Reduce `padding: 10px 12px 12px` to tighter values at <480px.
```css
@media (max-width: 479px) {
.chronology-item {
padding: 8px 8px 10px;
}
}
```
---
## Phase 3: KPI Grid Fix (Critical)
### 3A. Make KPI grid responsive (`PatientSummaryTile.tsx`)
**What:** Change KPI grid from hardcoded 2-column to responsive.
**How:** Use a CSS class instead of inline `gridTemplateColumns`:
```css
/* Default: 2 columns */
.kpi-grid {
display: grid;
gap: 10px;
grid-template-columns: repeat(2, minmax(0, 1fr));
}
/* Single column at very narrow viewports */
@media (max-width: 359px) {
.kpi-grid {
grid-template-columns: 1fr;
}
}
```
At 360px+ with 2 columns: each card gets ~160px (after removing sidebar, with 12px padding). That's workable.
At <360px (iPhone SE): single column, full width.
### 3B. Reduce KPI value font size at narrow viewports (`PatientSummaryTile.tsx`)
**What:** Reduce `fontSize: '30px'` on metric values.
**How:** Use `clamp()` or media query: `fontSize: 'clamp(22px, 6vw, 30px)'` — scales from 22px at 320px to 30px at 500px.
---
## Phase 4: Project Carousel Fix (Critical)
### 4A. Use 1 card per view at <480px (`ProjectsTile.tsx`)
**What:** Change `cardsPerView` logic:
```js
const cardsPerView = useMemo(() => {
if (viewportWidth < 480) return 1 // NEW: 1 card at small mobile
if (viewportWidth < 768) return 2
return 4
}, [viewportWidth])
```
At 320px with no sidebar: usable width ~296px → 1 card at ~296px is great.
### 4B. Reduce card min-height at <480px (`ProjectsTile.tsx`)
**What:** Add a smaller min-height tier:
```js
if (viewportWidth < 480) return 148
if (viewportWidth < 640) return 168
```
---
## Phase 5: Timeline & Text Overflow (Important)
### 5A. Allow timeline badges to wrap (`TimelineInterventionsSubsection.tsx`)
**What:** Change the badge container from `flexShrink: 0` to allow wrapping at narrow widths.
**How:** Add `flexWrap: 'wrap'` to the badge container and remove `flexShrink: 0`.
At very narrow widths, badges will wrap below the title instead of forcing overflow.
### 5B. Ensure ExpandableCardShell doesn't clip text (`ExpandableCardShell.tsx`)
**What:** The inner wrapper has `overflow: 'hidden'` which is needed for animation but could clip header text.
**Status:** Currently OK — the `minWidth: 0` on flex children handles text wrapping. The header has `gap: '8px'` and text naturally wraps. No change needed, but monitor.
---
## Phase 6: Constellation Graph (Important)
### 6A. Reduce constellation height at <480px (`useForceSimulation.ts`)
**What:** Change `getHeight()` to return a smaller height for very narrow viewports:
```js
function getHeight(width: number, containerHeight?: number | null): number {
if (width < 480) return 380 // NEW: shorter for small phones
if (width < 768) return 520
if (containerHeight && containerHeight > 0) return Math.max(400, containerHeight)
return 400
}
```
520px is disproportionate at 320px wide. 380px keeps it visible without dominating the view.
---
## Phase 7: Detail Panel Polish (Minor)
### 7A. Reduce detail panel body padding at narrow widths (`DetailPanel.tsx`)
**What:** Change `padding: '24px'` to `padding: '16px'` at <480px.
**How:** Add responsive CSS or inline viewport check:
```css
@media (max-width: 479px) {
.detail-panel .detail-panel-body {
padding: 16px;
}
}
```
Or add a `className` to the body div and use CSS.
### 7B. Reduce detail panel header padding (`DetailPanel.tsx`)
**What:** Change `padding: '20px 24px'` to `padding: '16px'` at <480px.
Same approach as 7A.
---
## Phase 8: Medications/Skills Grid (Minor)
### 8A. Already single-column on mobile (`index.css`)
**Status:** `.medications-grid` is already `grid-template-columns: 1fr` at mobile, going to 3 columns at 768px+. No change needed.
---
## Implementation Order
1. **Phase 1** (Sidebar → Bottom Nav) — Most impactful, recovers 64px
2. **Phase 2** (Spacing) — Recovers 16-32px more
3. **Phase 3** (KPI grid) — Fixes cramped cards
4. **Phase 4** (Carousel) — Fixes tiny project cards
5. **Phase 5** (Timeline) — Fixes potential text overflow
6. **Phase 6** (Constellation) — Better proportions
7. **Phase 7** (Detail panel) — Polish
8. **Phase 8** (Skills grid) — No change needed
## Width Budget After Fixes
| Viewport | Sidebar | Padding | Usable Width | Before |
|----------|---------|---------|--------------|--------|
| 320px | 0px | 24px | **296px** | 216px |
| 360px | 0px | 24px | **336px** | 256px |
| 375px | 0px | 24px | **351px** | 271px |
| 400px | 0px | 24px | **376px** | 296px |
| 430px | 0px | 24px | **406px** | 326px |
*At <480px: 12px padding each side = 24px total. Card padding: 16px each side = 32px total. Content area inside card: 232-374px.*
