iOS Safari auto-zooms (and shifts the viewport right) on focus when the computed font-size is <16px. Single @media (max-width: 767px) block in globals.css covers all four input tiers, every relevant bare <input> type, <textarea>, <select>, and contenteditable surfaces. `!important` is required because Tailwind utilities (text-[15px] on the chat composer, text-sm on form fields) emit after @layer components and would otherwise override the input-tier rules. Replaces ad-hoc per-input `text-base md:text-sm` overrides with a single global truth. New inputs/contenteditables get the fix for free. Spec: docs/systems/design-system.md gains an "iOS Auto-Zoom Suppression" section under Input Tiers.

# Design System — "Aether Drift"
|
|
|
|
Prototype (source of truth): `Backspace-design-prototype.html` (open in browser)
|
|
Styles: `packages/web/src/styles/globals.css`
|
|
Theme: `packages/web/tailwind.config.js`
|
|
Font: DM Sans (primary) with system fallbacks
|
|
|
|
---
|
|
|
|
## Principles
|
|
|
|
- Calm over flashy. Warm over cool.
|
|
- Quiet glass (felt, not seen). No decorative gradients. Minimal shadows.
|
|
- Two-material system: solid matte panels for content (75%), frosted glass bubbles for persistent controls (25%)
|
|
- `prefers-reduced-transparency` → fall back to solid surfaces
|
|
- NOT a Discord clone — Backspace has its own visual identity
|
|

## Surface Material Tiers
|
|
|
|
| Tier | Class | When to Use |
|
|
|------|-------|-------------|
|
|
| Structural | `bg-surface-*` | Permanent layout (sidebars, chat, member list) |
|
|
| Strip | `.glass-strip` | Persistent edge chrome (space sidebar) |
|
|
| Bubble | `.glass-bubble` | Persistent floating controls (voice bar, input pill) |
|
|
| Popover | `.glass` | Small floating surfaces (context menus, popovers, tooltips) |
|
|
| Tray dropdown | `.glass` (popover) | `TransferIndicator` global panel — anchored under the channel-header icon. |
|
|
| Modal | `.glass-modal` | Large center-screen dialogs |
|
|
| Pill | `.glass-pill` | Inline decorations (reactions, tags) |
|
|
| Pill (own) | `.glass-pill-mine` | User's own reaction (mint-tinted) |
|
|
|
|
**Rule:** If it floats above the content plane, it's glass. Never use `bg-surface-elevated` for floating/overlay elements.
|
|
|
|
**Modal backdrops:** `bg-black/50` — light enough for glass blur to show through.
|
|
|
|
**Portal target — `usePortalContainer()`:** Every overlay (context menu, tooltip, popover, modal, screen-share picker) MUST portal through `usePortalContainer()` (`packages/web/src/hooks/usePortalContainer.ts`) instead of hard-coding `document.body`. The hook returns `document.fullscreenElement ?? document.body` and re-renders subscribers on `fullscreenchange`. Without this, anything portaled while an element (e.g. the voice container in fullscreen mode) is in the browser's Fullscreen API top-layer is rendered outside that layer and is invisible. Components mounted at App root that render with `fixed inset-0` (not just portals) must also portal through this hook for the same reason.
|
|
|
|
### Glass Material Properties
|
|
```css
|
|
.glass {
|
|
backdrop-filter: blur(20px) saturate(120%);
|
|
background: rgba(20, 20, 26, 0.52); /* --glass-bg */
|
|
border: 1px solid rgba(255, 255, 255, 0.07); /* --glass-border */
|
|
}
|
|
.glass-modal {
|
|
/* Higher opacity: 82%, stronger shadow */
|
|
}
|
|
.glass-pill {
|
|
backdrop-filter: blur(12px) saturate(110%);
|
|
}
|
|
```
|
|
|
|

|
|
|
|
## Input Tiers
|
|
|
|
All defined in `globals.css`. No resting border — sunken `surface-input` background provides differentiation.
|
|
|
|
| Tier | Class | When to Use | Focus |
|
|
|------|-------|-------------|-------|
|
|
| Standard | `.input-standard` | Form fields in modals, settings, auth | `ring-2` primary |
|
|
| Search | `.input-search` | Search bars, filter inputs | `ring-1` primary |
|
|
| Embedded | `.input-embedded` | Inside glass (chat input, search popover) | none |
|
|
| Danger | `.input-danger` | Destructive confirmations | `ring-2` rose |
|
|
|
|
Override padding/size with utilities: `input-standard w-full py-2.5`
|
|
|
|
### iOS Auto-Zoom Suppression
|
|
|
|
iOS Safari auto-zooms (and shifts the viewport right) on input focus when the computed `font-size` is below 16px. The `@media (max-width: 767px)` block in `globals.css` bumps every input tier — and bare `<input>`/`<textarea>`/`<select>` plus `[contenteditable]` — to `font-size: 16px !important`.
|
|
|
|
`!important` is required because Tailwind utilities like `text-[15px]` (used on the chat composer textarea) and `text-sm` (used on form fields) are emitted in the `@layer utilities` block, which comes after `@layer components` in the cascade and would otherwise override the input-tier rules. There is no legitimate reason to use a `<16px` font-size on a mobile input, so the override is universally correct.
|
|
|
|
When introducing a new input or contenteditable surface, no extra work is needed — the global rule covers it.
|

|
## Layout
|
|
|
|
3-column grid: 312px channel sidebar | main content | 240px members sidebar
|
|
Glass server strip overlays left 72px of channel sidebar.
|
|
Channel sidebar fully opaque with gradient at left edge feeding glass.
|

## Shadows
|
|
|
|
| Name | Use |
|
|
|------|-----|
|
|
| `header` | Top bars |
|
|
| `elevation-low` | Subtle lift |
|
|
| `elevation-high` | Dropdowns, popovers |
|
|
| `glass` | Glass surfaces |
|
|
| `input` | Input fields |
|
|

`fadeIn`, `slideUp`, `slideDown`, `typingFadeIn`, `gradientPulse`, `shimmer` (skeleton loading)
|
|
|
|
### Search
|
|
`search-flash`, `stepForward`, `stepBack`
|
|
|
|
### Call
|
|
`callRippleLiquid`, `callGlowSoft`, `callRefraction`, `callButtonBreath`
|
|
|
|

|
|
|
|
## Utility Classes
|
|
|
|
- `.no-scrollbar` — Hides scrollbars
|
|
- `.scrollbar-thin` — 4px thin scrollbars
|
|
- `.rounded-inherit` — Inherits border radius
|
|
- `.titlebar-drag` / `.titlebar-no-drag` — Electron window drag
|
|
- `.call-refraction` — Light shimmer overlay for call UI
|
|
|

|
## Primitives
|
|
|
|
### Radial Progress Ring
|
|
|
|
Used in `AttachmentProgress` overlays inside the optimistic bubble and the staged-files row. Implementation:
|
|
|
|
```css
|
|
background: conic-gradient(rgba(180, 220, 200, .85) <pct>%, rgba(255, 255, 255, .15) <pct>%);
|
|
```
|
|
|
|
Inner disk uses `bg-surface-overlay` to sit visually above the underlying tile thumbnail. Failed-state ring uses `bg-accent-rose/30`.
