## 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;
}
```

# 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);
```
