|
||||
├── Layout Components

│ ├── Container (max-width + padding)
|
||||
│ ├── Stack (vertical spacing)
|
||||

├── Display (hide/show at breakpoints)

```
|
||||
|
||||
## Spacing Scale
|
||||
|
||||
### Base Unit: 4px (0.25rem)
|
||||
|
||||
| Token | Value | Usage |
|
||||
|-------|-------|-------|
|
||||
| --space-1 | 0.25rem (4px) | Tight gaps, icon margins |
|
||||
| --space-2 | 0.5rem (8px) | Small gaps, button padding |
|
||||
| --space-3 | 0.75rem (12px) | Medium gaps |
|
||||
| --space-4 | 1rem (16px) | Standard padding |
|
||||
| --space-5 | 1.5rem (24px) | Section padding |
|
||||
| --space-6 | 2rem (32px) | Large sections |
|
||||
| --space-8 | 3rem (48px) | Page padding |
|
||||
| --space-10 | 4rem (64px) | Hero sections |
|
||||
|
||||
## Breakpoint System
|
||||
|
||||
### Mobile-First Approach
|
||||
|
||||
```css
|
||||
/* Base styles (mobile) */
|
||||
.component { ... }
|
||||
|
||||
/* Small devices */
|
||||
@media (min-width: 480px) { ... }
|
||||
|
||||
/* Medium devices */
|
||||
@media (min-width: 768px) { ... }
|
||||
|
||||
/* Large devices */
|
||||
@media (min-width: 1024px) { ... }
|
||||
|
||||
/* Extra large devices */
|
||||
@media (min-width: 1280px) { ... }
|
||||
```
|
||||
|
||||
## Component Patterns
|
||||
|
||||
### Container
|
||||
```css
|
||||
.container {
|
||||
width: 100%;
|
||||
max-width: min(1200px, 100vw - 2rem);
|
||||
margin-inline: auto;
|
||||
padding-inline: var(--space-4);
|
||||
}
|
||||
```
|
||||
|
||||
### Stack (Vertical Layout)
|
||||
```css
|
||||
.stack {
|
||||
display: flex;
|
||||
flex-direction: column;
|
||||
gap: var(--space-4);
|
||||
}
|
||||
|
||||
.stack-sm { gap: var(--space-2); }
|
||||
.stack-md { gap: var(--space-4); }
|
||||
.stack-lg { gap: var(--space-6); }
|
||||
```
|
||||
|
||||
### Row (Horizontal Layout)
|
||||
```css
|
||||
.row {
|
||||
display: flex;
|
||||
flex-wrap: wrap;
|
||||
gap: var(--space-4);
|
||||
align-items: center;
|
||||
}
|
||||
```
|
||||
|
||||
### Grid
|
||||
```css
|
||||
.grid {
|
||||
display: grid;
|
||||
gap: var(--space-4);
|
||||
grid-template-columns: repeat(auto-fit, minmax(min(100%, 300px), 1fr));
|
||||
}
|
||||
```
|
||||
|
||||
## Responsive Tables
|
||||
|
||||
### Mobile: Card Layout
|
||||
```css
|
||||
@media (max-width: 767px) {
|
||||
.table-responsive {
|
||||
display: block;
|
||||
}
|
||||
.table-responsive thead {
|
||||
display: none;
|
||||
}
|
||||
.table-responsive tbody tr {
|
||||
display: block;
|
||||
margin-bottom: var(--space-4);
|
||||
border: 1px solid var(--border);
|
||||
border-radius: 8px;
|
||||
padding: var(--space-4);
|
||||
}
|
||||
.table-responsive td {
|
||||
display: flex;
|
||||
justify-content: space-between;
|
||||
padding: var(--space-2) 0;
|
||||
border-bottom: 1px solid var(--border-light);
|
||||
}
|
||||
.table-responsive td::before {
|
||||
content: attr(data-label);
|
||||
font-weight: 600;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Dialog Sizing
|
||||
|
||||
```css
|
||||
.dialog {
|
||||
width: min(560px, 100vw - 2rem);
|
||||
max-height: min(800px, 100vh - 2rem);
|
||||
overflow-y: auto;
|
||||
}
|
||||
|
||||
.dialog-lg {
|
||||
width: min(800px, 100vw - 2rem);
|
||||
}
|
||||
|
||||
.dialog-fullscreen-mobile {
|
||||
width: 100vw;
|
||||
height: 100vh;
|
||||
max-height: 100vh;
|
||||
border-radius: 0;
|
||||
}
|
||||
|
||||
@media (min-width: 768px) {
|
||||
.dialog-fullscreen-mobile {
|
||||
width: min(560px, 100vw - 2rem);
|
||||
height: auto;
|
||||
max-height: min(800px, 100vh - 2rem);
|
||||
border-radius: 12px;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Touch Targets
|
||||
|
||||
```css
|
||||
.button,
|
||||
.nav-link,
|
||||
.icon-button {
|
||||
min-height: 44px;
|
||||
min-width: 44px;
|
||||
}
|
||||
|
||||
/* Larger touch targets on mobile */
|
||||
@media (max-width: 767px) {
|
||||
.button {
|
||||
padding: var(--space-3) var(--space-4);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Text Handling
|
||||
|
||||
```css
|
||||
.truncate {
|
||||
overflow: hidden;
|
||||
text-overflow: ellipsis;
|
||||
white-space: nowrap;
|
||||
}
|
||||
|
||||
.truncate-multiline {
|
||||
display: -webkit-box;
|
||||
-webkit-line-clamp: 3;
|
||||
-webkit-box-orient: vertical;
|
||||
overflow: hidden;
|
||||
}
|
||||
|
||||
.break-word {
|
||||
overflow-wrap: break-word;
|
||||
word-wrap: break-word;
|
||||
hyphens: auto;
|
||||
}
|
||||
```
|
||||
|
||||
## Migration Strategy
|
||||
|
||||
### Phase 1: CSS Custom Properties
|
||||
- Add spacing scale to :root
|
||||
- Add breakpoint custom properties
|
||||
- Add fluid typography
|
||||
|
||||
### Phase 2: Layout Utilities
|
||||
- Create Container, Stack, Row, Grid utilities
|
||||
- Update existing layouts to use utilities
|
||||
|
||||
### Phase 3: Component Updates
|
||||
- Update all pages with responsive patterns
|
||||
- Fix overflow issues
|
||||
- Add touch-friendly sizing
|
||||
|
||||
### Phase 4: Testing
|
||||
- Test on multiple viewport sizes
|
||||
- Verify no horizontal overflow
|
||||
- Check touch target sizes

# Responsive Spacing Improvements
|
||||
|
||||
## Problem
|
||||
|
||||
The current UI has several spacing and sizing issues that cause poor user experience:
|
||||
|
||||
1. **Overflow on small screens** - Tables, dialogs, and workspace layouts don't adapt to mobile viewports
|
||||
2. **Inconsistent spacing** - Components use arbitrary padding/margin values without a consistent scale
|
||||
3. **Fixed widths** - Many components use fixed pixel widths that break on smaller screens
|
||||
4. **Missing responsive breakpoints** - Only 3 media queries exist for the entire application (860px, 1024px, 768px)
|
||||
5. **Text truncation** - Long content overflows containers without proper ellipsis handling
|
||||
6. **Touch targets** - Buttons and links are too small for mobile interaction (below 44px minimum)
|
||||
|
||||
## Solution
|
||||
|
||||
Implement a comprehensive responsive design system with:
|
||||
|
||||
1. **Consistent spacing scale** - Use CSS custom properties for padding/margin (4px base unit)
|
||||
2. **Mobile-first breakpoints** - Standard breakpoints at 480px, 768px, 1024px, 1280px
|
||||
3. **Fluid layouts** - Replace fixed widths with relative units (%, vw, clamp())
|
||||
4. **Responsive tables** - Horizontal scroll or card-based layout for tables on mobile
|
||||
5. **Dialog sizing** - Max-width constraints with viewport-relative sizing
|
||||
6. **Touch-friendly targets** - Minimum 44px touch targets for all interactive elements
|
||||
|
||||
## Key Features
|
||||
|
||||
### Spacing Scale
|
||||
```
|
||||
--space-1: 0.25rem (4px)
|
||||
--space-2: 0.5rem (8px)
|
||||
--space-3: 0.75rem (12px)
|
||||
--space-4: 1rem (16px)
|
||||
--space-5: 1.5rem (24px)
|
||||
--space-6: 2rem (32px)
|
||||
--space-8: 3rem (48px)
|
||||
--space-10: 4rem (64px)
|
||||
```
|
||||
|
||||
### Breakpoint System
|
||||
```
|
||||
sm: 480px - Mobile landscape
|
||||
md: 768px - Tablet
|
||||
lg: 1024px - Desktop
|
||||
xl: 1280px - Large desktop
|
||||
```
|
||||
|
||||
### Fluid Typography
|
||||
```
|
||||
--font-size-sm: clamp(0.75rem, 0.7rem + 0.25vw, 0.875rem);
|
||||
--font-size-base: clamp(0.875rem, 0.8rem + 0.35vw, 1rem);
|
||||
--font-size-lg: clamp(1rem, 0.9rem + 0.5vw, 1.25rem);
|
||||
--font-size-xl: clamp(1.25rem, 1.1rem + 0.75vw, 1.5rem);
|
||||
```
|
||||
|
||||
## Success Criteria
|
||||
|
||||
- [ ] All pages display correctly on screens from 320px to 2560px
|
||||
- [ ] No horizontal overflow on any page at any breakpoint
|
||||
- [ ] All interactive elements have minimum 44px touch target
|
||||
- [ ] Consistent spacing using CSS custom properties
|
||||
- [ ] Tables are readable on mobile (horizontal scroll or card layout)
|
||||
- [ ] Dialogs fit within viewport with proper padding
