# OpenSpec Spec: Web UI Foundations — Spacing, Typography & Visual Rhythm
## Change
`web-ui-spacing-typography-rework` — Pass 1: Foundations
## Parent Proposal
`openspec/proposals/web-ui-spacing-typography-rework.md`
## Status
spec
---
## 1. Scope of This Spec
This spec covers **Pass 1 (Foundations)** only:
- Expand `apps/web/src/styles/tokens.css` with missing primitives.
- Add missing primitive component styles to `apps/web/src/styles/global.css` and `apps/web/src/styles/utilities.css`.
- Fix mobile navigation / FAB / bottom-sheet collisions via a shared `--mobile-nav-height` token.
- Replace critical inline font-size violations (`0.7rem`) with token values.
- Add visible focus states to interactive controls.
- Provide full CSS for the currently unstyled mobile detail view.
Out of scope for Pass 1:
- Refactoring inline styles in editor components (Pass 2).
- Modal/dialog unification (Pass 3).
- Card/badge consolidation across page CSS files (Pass 3).
- Breakpoint standardization beyond the safe-area/mobile-nav work (Pass 3).
---
## 2. Token Additions
Add to `apps/web/src/styles/tokens.css` **without renaming or removing existing tokens**.
### 2.1 Spacing
```css
--space-7: 2.5rem;
--space-9: 5rem;
--space-12: 6rem;
```
### 2.2 Border Radius
```css
--radius-sm: 6px;
--radius-md: 10px;
--radius-lg: 14px;
--radius-xl: 16px;
--radius-full: 999px;
```
### 2.3 Line Height
```css
--line-height-tight: 1.25;
--line-height-normal: 1.5;
--line-height-relaxed: 1.75;
```
### 2.4 Shadow / Elevation
```css
--shadow-sm: 0 1px 2px rgba(0, 0, 0, 0.04);
--shadow-md: 0 4px 12px rgba(0, 0, 0, 0.08);
--shadow-lg: 0 8px 24px rgba(0, 0, 0, 0.12);
--shadow-xl: 0 12px 40px rgba(0, 0, 0, 0.18);
```
### 2.5 Layout & Touch
```css
--touch-target: 44px;
--sidebar-width: 280px;
--mobile-nav-height: calc(64px + env(safe-area-inset-bottom, 0px));
```
### 2.6 Token Documentation Header
Add a short comment block at the top of `tokens.css` describing the naming convention and scales, so future contributors know which token to reach for.
---
## 3. Primitive Component Styles
Add the following classes to `apps/web/src/styles/global.css` unless noted otherwise.
### 3.1 Buttons
Unify the existing ad-hoc button usage. The codebase already references `.btn`, `.btn-primary`, `.btn-secondary`, `.btn-sm` in many places.
```css
.btn {
display: inline-flex;
align-items: center;
justify-content: center;
gap: var(--space-2);
min-height: var(--touch-target);
padding: var(--space-2) var(--space-4);
border: 1px solid transparent;
border-radius: var(--radius-md);
font-size: var(--font-size-sm);
font-weight: 500;
line-height: var(--line-height-tight);
background: var(--panel);
color: var(--ink);
cursor: pointer;
transition: background 0.12s ease, border-color 0.12s ease, color 0.12s ease;
}
.btn:focus-visible {
outline: 2px solid var(--brand);
outline-offset: 2px;
}
.btn-primary {
background: var(--brand);
color: var(--primary-fg);
border-color: var(--brand);
}
.btn-primary:hover {
background: var(--brand-strong);
border-color: var(--brand-strong);
}
.btn-secondary {
background: var(--panel);
color: var(--ink);
border-color: var(--border);
}
.btn-secondary:hover {
background: var(--bg);
}
.btn-sm {
min-height: calc(var(--touch-target) - 8px);
padding: var(--space-1) var(--space-3);
font-size: var(--font-size-xs);
}
.btn:disabled,
.btn[aria-disabled="true"] {
opacity: 0.55;
cursor: not-allowed;
}
```
### 3.2 Link Button
```css
.link-button {
display: inline-flex;
align-items: center;
gap: var(--space-1);
padding: 0;
background: transparent;
border: none;
color: var(--brand);
font-size: inherit;
font-weight: 500;
cursor: pointer;
text-decoration: none;
}
.link-button:hover {
text-decoration: underline;
}
.link-button:focus-visible {
outline: 2px solid var(--brand);
outline-offset: 2px;
border-radius: var(--radius-sm);
}
```
### 3.3 Form Inputs
Add a baseline `.form-input` class and a `.form-textarea` modifier.
```css
.form-input,
.form-textarea {
width: 100%;
min-height: var(--touch-target);
padding: var(--space-2) var(--space-3);
border: 1px solid var(--border);
border-radius: var(--radius-md);
background: var(--panel);
color: var(--ink);
font-size: var(--font-size-base);
line-height: var(--line-height-normal);
}
.form-input:focus,
.form-textarea:focus {
outline: none;
border-color: var(--brand);
box-shadow: 0 0 0 2px color-mix(in srgb, var(--brand) 20%, transparent);
}
.form-input::placeholder,
.form-textarea::placeholder {
color: var(--muted);
}
.form-textarea {
min-height: 6rem;
resize: vertical;
}
```
### 3.4 Checkbox Label
```css
.checkbox-label {
display: inline-flex;
align-items: center;
gap: var(--space-2);
min-height: var(--touch-target);
font-size: var(--font-size-sm);
color: var(--ink);
cursor: pointer;
}
.checkbox-label input[type="checkbox"] {
width: 1.125rem;
height: 1.125rem;
accent-color: var(--brand);
}
```
### 3.5 Hint Text
```css
.hint {
font-size: var(--font-size-sm);
color: var(--muted);
line-height: var(--line-height-normal);
}
```
### 3.6 Error Message
```css
.form-error,
.error-message {
display: flex;
align-items: center;
gap: var(--space-2);
padding: var(--space-2) var(--space-3);
border-radius: var(--radius-md);
background: var(--danger-light);
color: var(--danger);
font-size: var(--font-size-sm);
line-height: var(--line-height-normal);
}
```
### 3.7 Alert Banner
```css
.alert {
display: flex;
align-items: flex-start;
gap: var(--space-3);
padding: var(--space-3) var(--space-4);
border-radius: var(--radius-md);
border: 1px solid var(--border);
background: var(--panel);
color: var(--ink);
font-size: var(--font-size-sm);
line-height: var(--line-height-normal);
}
.alert-error {
background: var(--danger-light);
border-color: color-mix(in srgb, var(--danger) 30%, transparent);
color: var(--danger);
}
.alert-warning {
background: var(--warning-light);
border-color: color-mix(in srgb, var(--warning) 30%, transparent);
color: var(--warning);
}
.alert-info {
background: var(--info-light);
border-color: color-mix(in srgb, var(--info) 30%, transparent);
color: var(--info);
}
```
### 3.8 Loading State
```css
.loading-state {
display: flex;
align-items: center;
justify-content: center;
gap: var(--space-2);
padding: var(--space-4);
color: var(--muted);
font-size: var(--font-size-sm);
}
```
### 3.9 Badges
```css
.badge {
display: inline-flex;
align-items: center;
gap: var(--space-1);
padding: var(--space-1) var(--space-2);
border-radius: var(--radius-full);
font-size: var(--font-size-xs);
font-weight: 600;
line-height: var(--line-height-tight);
background: var(--bg);
color: var(--muted);
border: 1px solid var(--border);
}
.badge-success {
background: var(--success-light);
color: var(--success);
border-color: color-mix(in srgb, var(--success) 30%, transparent);
}
.badge-secondary {
background: var(--info-light);
color: var(--info);
border-color: color-mix(in srgb, var(--info) 30%, transparent);
}
```
### 3.10 Text Utilities
Add `.text-muted` as an alias for existing muted text patterns. The codebase references `.text-muted` in `mobile-detail-view.tsx`.
```css
.text-muted {
color: var(--muted);
}
```
---
## 4. Mobile Detail View Styles
Add to `apps/web/src/styles/utilities.css` (these classes are referenced only in mobile components and fit the utilities file).
```css
.mobile-detail-view {
display: flex;
flex-direction: column;
min-height: 100%;
background: var(--bg);
}
.mobile-detail-header {
position: sticky;
top: 0;
z-index: 10;
display: flex;
align-items: center;
gap: var(--space-3);
padding: var(--space-3);
background: var(--panel);
border-bottom: 1px solid var(--border);
}
.mobile-detail-header-content {
flex: 1;
min-width: 0;
}
.mobile-detail-title {
margin: 0;
font-size: var(--font-size-lg);
line-height: var(--line-height-tight);
}
.mobile-detail-subtitle {
margin: var(--space-1) 0 0;
color: var(--muted);
font-size: var(--font-size-sm);
line-height: var(--line-height-normal);
}
.mobile-detail-actions {
display: flex;
gap: var(--space-2);
}
.mobile-detail-fields {
display: flex;
flex-direction: column;
gap: var(--space-3);
padding: var(--space-3);
}
.mobile-detail-field {
display: flex;
flex-direction: column;
gap: var(--space-1);
padding: var(--space-3);
background: var(--panel);
border: 1px solid var(--border);
border-radius: var(--radius-md);
}
.mobile-detail-field-label {
font-size: var(--font-size-xs);
font-weight: 600;
text-transform: uppercase;
letter-spacing: 0.05em;
color: var(--muted);
}
.mobile-detail-field-value {
font-size: var(--font-size-base);
color: var(--ink);
line-height: var(--line-height-normal);
word-break: break-word;
}
.mobile-detail-code {
overflow: auto;
max-width: 100%;
font-size: var(--font-size-sm);
line-height: var(--line-height-normal);
}
```
### 4.1 Mobile List Search
```css
.mobile-list-search {
padding: var(--space-3);
border-bottom: 1px solid var(--border);
background: var(--panel);
}
.mobile-list-search-input {
width: 100%;
min-height: var(--touch-target);
padding: var(--space-2) var(--space-3);
border: 1px solid var(--border);
border-radius: var(--radius-md);
background: var(--bg);
color: var(--ink);
font-size: var(--font-size-base);
}
.mobile-list-search-input:focus {
outline: none;
border-color: var(--brand);
}
```
---
## 5. Mobile Nav / FAB / Bottom-Sheet Collisions
### 5.1 Replace Magic Numbers
Wherever the mobile nav height is hardcoded as `64px`, switch to `var(--mobile-nav-height)`.
Affected selectors (verify current line numbers before editing):
- `.mobile-nav` in `utilities.css`
- `.mobile-edit-actions` in `utilities.css`
- `.shell-content.mobile` in `utilities.css`
- `.start-tool-fab` in `global.css`
- `.mobile-bottom-sheet` / `.mobile-action-sheet` if present
### 5.2 Start Tool FAB
```css
.start-tool-fab {
position: fixed;
bottom: calc(var(--mobile-nav-height) + var(--space-3));
right: var(--space-4);
z-index: 50;
}
```
### 5.3 Shell Content Padding
```css
.shell-content.mobile {
padding-bottom: calc(var(--mobile-nav-height) + var(--space-3));
}
```
### 5.4 Mobile Edit Actions
```css
.mobile-edit-actions {
position: fixed;
bottom: var(--mobile-nav-height);
/* existing left/right rules preserved */
}
```
---
## 6. Focus States
Add visible focus rings to the following selectors in `global.css`/`utilities.css`.
```css
.nav-item:focus-visible,
.mobile-nav-item:focus-visible,
.tab:focus-visible,
.tree-entry:focus-visible,
.btn:focus-visible,
.form-input:focus-visible,
.form-textarea:focus-visible,
.link-button:focus-visible,
.checkbox-label input:focus-visible {
outline: 2px solid var(--brand);
outline-offset: 2px;
}
```
For `.nav-item-active` and `.tab.active`, use `--primary-fg` or a high-contrast outline color if `--brand` is insufficient.
---
## 7. Inline Font-Size Violations
Replace inline `style={{ fontSize: "0.7rem" }}` and similar hardcoded values with token-based classes.
Known locations (verify before editing):
- `ConfigProfileListSidebar.tsx` lines 82, 95
- Any other `0.7rem`/`11px`/`10px` inline styles found during implementation
Use `.text-xs` or add a `.text-xs` utility mapped to `--font-size-xs` if it does not already exist. If a component truly needs smaller than `--font-size-xs`, escalate instead of adding a new smaller token.
---
## 8. SSH Key Page Styles
Add missing styles for the signing/verification sections in `SSHKeyList.tsx`.
```css
.key-signing,
.key-verification {
display: flex;
flex-direction: column;
gap: var(--space-3);
padding: var(--space-3);
background: var(--panel);
border: 1px solid var(--border);
border-radius: var(--radius-md);
margin-top: var(--space-3);
}
.signature-result,
.verify-result {
padding: var(--space-3);
border-radius: var(--radius-md);
background: var(--bg);
border: 1px solid var(--border);
font-family: "IBM Plex Mono", monospace;
font-size: var(--font-size-sm);
word-break: break-all;
}
```
---
## 9. Profile Page Avatar Styles
Add fallback styles for the avatar section used in `ProfilePage.tsx`.
```css
.profile-avatar-section {
display: flex;
flex-direction: column;
align-items: center;
gap: var(--space-3);
padding: var(--space-4);
background: var(--panel);
border: 1px solid var(--border);
border-radius: var(--radius-md);
}
.avatar-preview,
.avatar-placeholder {
width: 6rem;
height: 6rem;
border-radius: var(--radius-full);
overflow: hidden;
display: flex;
align-items: center;
justify-content: center;
background: var(--bg);
border: 2px solid var(--border);
}
.avatar-image {
width: 100%;
height: 100%;
object-fit: cover;
}
.avatar-placeholder {
font-size: var(--font-size-2xl);
font-weight: 600;
color: var(--muted);
}
```
---
## 10. Acceptance Criteria
- [ ] `tokens.css` contains all new tokens from §2 and a documentation header.
- [ ] All class names listed in §3–§9 have working CSS rules.
- [ ] No referenced class in the audited report remains undefined (verified by searching for the class names and confirming a rule exists).
- [ ] Mobile detail view renders with proper padding, label/value hierarchy, and bounded code blocks.
- [ ] Mobile nav, FAB, edit actions, and shell content no longer collide on devices with safe-area insets.
- [ ] All interactive controls have visible `:focus-visible` rings.
- [ ] Inline `0.7rem` font sizes are replaced with token-based classes.
- [ ] `npm run typecheck` passes in `apps/web`.
- [ ] `npm run lint` passes in `apps/web`.
- [ ] No visual changes to desktop pages beyond improved spacing/consistency.
---
## 11. Verification Plan
1. Run `cd apps/web && npm run typecheck`.
2. Run `cd apps/web && npm run lint`.
3. Search for each undefined class from the audit and confirm it now has a rule.
4. Open the mobile detail view in a narrow viewport and verify layout.
5. Open the SSH keys page and verify signing/verification sections.
6. Open the profile page and verify avatar styling.
---
## 12. Next Phase
After this spec is approved, create **tasks** for Pass 1 implementation, then delegate to `sdd-apply`.
