# Brave Search Frontend Redesign — Design Specification
## Overview
Redesign the samsa frontend to match Brave Search's clean, functional aesthetic with emphasis on layout changes: three-column results page, category tiles on homepage, and a hybrid preferences system with full-page `/preferences` route.
## Design Principles
1. **Brave-like layout** — Three-column results, full-page preferences, homepage tiles
2. **Preserve existing design tokens** — Keep current CSS variables (colors, spacing, radii)
3. **CSS Grid for layout** — Three-column grid for results, flexible layouts elsewhere
4. **Hybrid preferences** — Quick popover for common settings (theme + engines), full `/preferences` page for all options
5. **Minimal HTML changes** — Restructure templates where needed for layout, reuse existing partials
6. **localStorage-only preferences** — No server-side persistence; all preferences stored in browser localStorage
---
## 1. Homepage Redesign
### Current State
- Centered hero with logo, tagline, and search box
- No visual categorization of search types
### New Layout
```
┌─────────────────────────────────────────────────────────────┐
│ [Logo] [⚙ Preferences]│
├─────────────────────────────────────────────────────────────┤
│ │
│ [🔍 Search Box] │
│ │
│ ┌────────┐ ┌────────┐ ┌────────┐ ┌────────┐ │
│ │ News │ │ Images │ │ Videos │ │ Maps │ ... │
│ └────────┘ └────────┘ └────────┘ └────────┘ │
│ │
│ "Search the web privately..." │
│ │
└─────────────────────────────────────────────────────────────┘
```
### Implementation
- **File:** `internal/views/templates/index.html`
- **Structure:** Search hero + category tiles grid
- **Tiles:** Static links to `/search?q=...` with category parameter (e.g., `&category=images`)
- **Styling:** Grid of icon+label cards below search box, subtle hover effects
### Category Tiles
| Category | Icon | Notes |
|----------|------|-------|
| All | 🌐 | Default, no category param |
| News | 📰 | |
| Images | 🖼️ | |
| Videos | 🎬 | |
| Maps | 🗺️ | |
| Shopping | 🛒 | Future: connect to shopping engine |
| Music | 🎵 | Future: connect to music engine |
| Weather | 🌤️ | Future: connect to weather API |
| Sports | ⚽ | Future |
| Cryptocurrency | ₿ | Future |
Categories marked "Future" are included in the UI but may not have backend support yet. Category tiles that lack backend support display grayed out with a "Coming soon" tooltip.
---
## 2. Results Page — Three-Column Layout
### Current State
- Two columns: compact search bar spanning top, main results + right sidebar
### New Layout
```
┌─────────────────────────────────────────────────────────────┐
│ [Logo] [⚙ Preferences]│
├─────────────────────────────────────────────────────────────┤
│ ┌─────────┐ ┌────────────────────────────┐ ┌──────────┐│
│ │ Nav │ │ 🔍 [ Search Input ] │ │ Related ││
│ │ ─────── │ └────────────────────────────┘ │ Searches ││
│ │ All │ About 1,240 results (0.42s) │ ││
│ │ Images │ ┌──────────────────────────┐ │ │ ─────── ││
│ │ Videos │ │ Result Card │ │ │ Suggestions│
│ │ News │ │ Title, URL, Description │ │ │ ││
│ │ Maps │ └──────────────────────────┘ │ └──────────┘│
│ │ Shopping│ ┌──────────────────────────┐ │ │
│ │ ... │ │ Result Card │ │ │
│ │ │ │ ... │ │ │
│ │ ─────── │ └──────────────────────────┘ │ │
│ │ Filters │ ... │ │
│ │ Time │ │ │
│ │ Type │ [Pagination] │ │
│ └─────────┘ │ │
└─────────────────────────────────────────────────────────────┘
```
### Implementation
- **Files:** `internal/views/templates/results.html`, `internal/views/templates/base.html`
- **Left Sidebar (desktop, sticky):**
- Category navigation links (All, Images, Videos, News, Maps, Shopping, Music, Weather)
- Filters section (Time range, Result type) — collapsible
- Hidden on mobile (< 768px)
- **Center Column:**
- Compact search bar
- Results count meta: "About {n} results ({time}s)"
- Result cards (unchanged markup)
- Pagination
- **Right Sidebar:**
- Related searches (existing suggestions)
- Additional panels as needed
### Filters
**Time Range Options:**
| Label | Query Param |
|-------|-------------|
| Any time | (none) |
| Past hour | `&time=h` |
| Past 24 hours | `&time=d` |
| Past week | `&time=w` |
| Past month | `&time=m` |
| Past year | `&time=y` |
**Result Type Options:**
| Label | Query Param |
|-------|-------------|
| All results | (none) |
| News | `&type=news` |
| Videos | `&type=video` |
| Images | `&type=image` |
Filter state persists in URL query params and is preserved across HTMX navigation via `hx-include`.
### Mobile Behavior
| Breakpoint | Layout |
|------------|--------|
| < 768px | Single column, no left sidebar |
| 768px - 1024px | Two columns (center + right sidebar), no left nav |
| > 1024px | Full three columns |
On mobile (< 768px):
- Category filters accessible via a horizontal scrollable chip row above results
- Both sidebars hidden
- Search bar full-width
---
## 3. Preferences Page — Full-Page Hybrid
### Current State
- Popover triggered by gear icon in header
- JavaScript-rendered from localStorage
- Sections: Appearance, Engines, Search Defaults
### New Layout
```
┌─────────────────────────────────────────────────────────────┐
│ [Logo] [⚙ Preferences]│
├─────────────────────────────────────────────────────────────┤
│ ┌────────────────┐ ┌─────────────────────────────────────┐│
│ │ Nav │ │ Content ││
│ │ ───────────── │ │ ││
│ │ Search │ │ [Section Content] ││
│ │ Privacy │ │ ││
│ │ Tabs │ │ ││
│ │ Appearance │ │ ││
│ │ Sidebar │ │ ││
│ │ Content │ │ ││
│ │ Languages │ │ ││
│ │ Regional │ │ ││
│ └────────────────┘ └─────────────────────────────────────┘│
└─────────────────────────────────────────────────────────────┘
```
### Sections (Brave-style)
1. **Search** — Default engine, safe search, language
2. **Privacy** — Tracking protection toggle (UI only, always on), request DNT header toggle
3. **Tabs** — New tab behavior (placeholder section)
4. **Appearance** — Theme (Light/Dark/System), results font size
5. **Sidebar** — Sidebar visibility toggle
6. **Content** — Filter explicit results (SafeSearch), auto-play media toggle
7. **Languages** — UI language (English only for now), search language
8. **Regional** — Region/Country, timezone (placeholder)
### Implementation
- **Route:** Add `GET /preferences` and `POST /preferences` to `internal/httpapi/`
- **Template:** `internal/views/templates/preferences.html`
- **Storage:** localStorage-only. GET handler renders page shell, JavaScript populates form values from localStorage. POST handler receives form data, writes to localStorage, re-renders page.
- **Quick Settings Popover:** Keep existing popover for **theme toggle and engine toggles only** (lightweight, localStorage). SafeSearch and Format settings move exclusively to full preferences page.
- **Styling:** Match existing design tokens, section headers, form controls
### Preferences Nav (Mobile)
- Horizontal scrollable nav on mobile (< 768px)
- Active section highlighted
---
## 4. Component Changes
### Header
- Logo + site name (unchanged)
- Preferences button (unchanged)
### Search Box
- Homepage: Larger, prominent, centered
- Results page: Compact, full-width within center column
### Result Cards
- Keep existing structure
- Consider subtle styling improvements (spacing, typography)
### Category Tiles (Homepage)
- Icon + label per category
- Hover: slight scale + shadow
### Left Sidebar (Results Page)
- Sticky positioning (`position: sticky; top: calc(var(--header-height) + 1rem)`)
- Category links with active state indicator
- Collapsible filter sections
### Preferences Nav
- Vertical nav with section icons
- Active state indicator
- Mobile: horizontal scroll
---
## 5. CSS Architecture
### Existing (Retain)
- CSS custom properties (design tokens)
- Component-level styles
- Dark mode via `[data-theme="dark"]`
### New
**Layout Grid for three-column results:**
```css
.results-layout {
display: grid;
grid-template-columns: 200px 1fr 240px;
gap: 2rem;
align-items: start;
}
```
**Sticky Left Sidebar:**
```css
.results-layout .left-sidebar {
position: sticky;
top: calc(var(--header-height) + 1.5rem);
max-height: calc(100vh - var(--header-height) - 3rem);
overflow-y: auto;
}
```
**Preferences page layout:**
```css
.preferences-layout {
display: grid;
grid-template-columns: 200px 1fr;
gap: 2rem;
}
```
**Category tiles grid:**
```css
.category-tiles {
display: grid;
grid-template-columns: repeat(auto-fill, minmax(100px, 1fr));
gap: 1rem;
}
```
**Mobile breakpoints:**
```css
@media (max-width: 768px) {
.results-layout {
grid-template-columns: 1fr;
}
.results-layout .left-sidebar,
.results-layout .right-sidebar {
display: none;
}
}
@media (min-width: 769px) and (max-width: 1024px) {
.results-layout {
grid-template-columns: 1fr 220px;
}
.results-layout .left-sidebar {
display: none;
}
}
```
---
## 6. Files to Modify
| File | Change |
|------|--------|
| `internal/views/templates/index.html` | Add category tiles |
| `internal/views/templates/results.html` | Add left sidebar, restructure for three columns |
| `internal/views/templates/base.html` | Minimal changes (no structural changes needed) |
| `internal/views/templates/preferences.html` | **New** — full preferences page |
| `internal/views/static/css/samsa.css` | Add layout grids, category tiles, sidebar styles, sticky positioning, mobile breakpoints |
| `internal/views/static/js/settings.js` | Reduce popover to theme + engines; add preferences page JS |
| `internal/httpapi/httpapi.go` | Add `/preferences` route (GET + POST) |
| `internal/views/views.go` | Add preferences template rendering |
---
## 7. Priority Order
1. **Phase 1:** CSS layout framework (three-column grid, new variables, breakpoints)
2. **Phase 2:** Results page three-column layout
3. **Phase 3:** Homepage category tiles
4. **Phase 4:** Preferences page (quick popover first, then full page)
5. **Phase 5:** Polish and mobile responsiveness
---
## Out of Scope
- Backend search logic changes
- New engine implementations (category tiles for future engines are UI placeholders only)
- Caching or performance improvements
- User authentication/account system
- Server-side preference storage

# Settings UI Design — samsa
**Date:** 2026-03-22
**Status:** Approved
## Overview
A lightweight preferences popover anchored to the top-right, just below the header. Triggered by a gear icon, it lets users adjust theme, enabled engines, and search defaults without leaving their current page. All changes auto-save to `localStorage` on every interaction.
## Layout & Structure
- **Trigger**: Gear icon (⚙️) in the top-right header, aligned with the header's right edge
- **Panel**: 280px wide, max-height 420px, scrollable internally, rounded corners, subtle shadow, anchored top-right (drops down from trigger, like a dropdown)
- **Close**: × button in panel header, click outside the panel, or pressing Escape
- **No Save button** — every interaction immediately writes to `localStorage`
## Interaction Flow
1. User clicks ⚙️ → panel drops down from top-right (200ms ease)
2. User toggles/clicks → changes apply instantly to DOM + write to `localStorage`
3. User clicks × or outside or Escape → panel closes, settings persist
4. **Accessibility**: Focus is trapped within the panel while open. Trigger button uses `aria-expanded` and `aria-controls`. Escape key closes the panel.
## Mid-Search Changes
When opened during an active search on `results.html`:
- Engine toggles update `localStorage` immediately, but **current results remain unchanged**
- A subtle inline note below the engines section: *"Engine changes apply to your next search"*
## Sections
### Appearance
- Three theme buttons: ☀️ Light / 🌙 Dark / 💻 System
- Clicking immediately applies via `document.body.classList` + writes to localStorage
- "System" reads `prefers-color-scheme` and updates on change
### Engines
- 2-column grid of toggle switches for all 9 engines
- Each row: engine name + toggle switch
- Enabled = filled accent color; Disabled = gray outline
### Search Defaults
- Safe search: dropdown (Moderate / Strict / Off)
- Default format: dropdown (HTML / JSON / CSV)
## Default State
```js
const DEFAULT_PREFS = {
theme: "system",
engines: ["wikipedia", "arxiv", "crossref", "braveapi", "qwant", "duckduckgo", "github", "reddit", "bing"],
safeSearch: "moderate",
format: "html"
};
```
## Persistence
```js
// Written on every interaction
localStorage.setItem('samsa_prefs', JSON.stringify({ ... }));
// Read on page load — merge with DEFAULT_PREFS
const saved = JSON.parse(localStorage.getItem('samsa_prefs') || '{}');
const prefs = { ...DEFAULT_PREFS, ...saved };
```
## Responsive Behavior
- **Mobile (<768px)**: Panel becomes a **bottom sheet** — 100% width, slides up from the bottom, top corners rounded, max-height 70vh. Trigger moves to a fixed bottom-right FAB button.
- Panel never covers the search input
## Applied to Existing Code
- `base.html` — add gear button in header, panel markup at end of `<body>`
- `samsa.css` — popover styles, toggle switch styles, bottom sheet styles for mobile
- `settings.js` — localStorage read/write, theme application, panel toggle, aria attributes, focus trap
