Brave Search Frontend Redesign — Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Redesign the kafka frontend to match Brave Search's layout: three-column results page, category tiles on homepage, and a hybrid preferences system with full-page /preferences route.

Architecture: CSS Grid for page-level layouts (three-column results, two-column preferences). JavaScript popover for quick settings (theme + engines only). Server-rendered full preferences page with localStorage persistence. Category tiles are static links with category query params.

Tech Stack: Go (Go templates), CSS Grid/Flexbox, Vanilla JavaScript (HTMX for search), localStorage for preferences

File Map

File	Responsibility
`internal/views/static/css/kafka.css`	Add layout grids, category tiles, sidebar styles, mobile breakpoints
`internal/views/templates/index.html`	Add category tiles below search box
`internal/views/templates/results.html`	Add left sidebar, restructure for three-column grid
`internal/views/templates/preferences.html`	New — full preferences page with nav
`internal/views/templates/base.html`	No structural changes needed
`internal/views/static/js/settings.js`	Reduce popover to theme + engines; add preferences page JS
`internal/httpapi/handlers.go`	Add `GET /preferences` and `POST /preferences` handlers
`internal/views/views.go`	Add `RenderPreferences` and `tmplPreferences` template

PHASE 1: CSS Layout Framework

Task 1: Add CSS Grid Layouts and Breakpoints

Files:

Modify: internal/views/static/css/kafka.css
Step 1: Add three-column results layout CSS

Append to end of kafka.css, before the @media print block:

/* ============================================================
   Three-Column Results Layout
   ============================================================ */

.results-layout {
  display: grid;
  grid-template-columns: 200px 1fr 240px;
  gap: 2rem;
  align-items: start;
}

.results-layout .left-sidebar {
  position: sticky;
  top: calc(var(--header-height) + 1.5rem);
  max-height: calc(100vh - var(--header-height) - 3rem);
  overflow-y: auto;
}

.results-layout .right-sidebar {
  position: sticky;
  top: calc(var(--header-height) + 1.5rem);
  max-height: calc(100vh - var(--header-height) - 3rem);
  overflow-y: auto;
}

.results-layout .results-column {
  min-width: 0;
}

Step 2: Add mobile breakpoints

/* Tablet: hide left sidebar, two columns */
@media (min-width: 769px) and (max-width: 1024px) {
  .results-layout {
    grid-template-columns: 1fr 220px;
  }
  .results-layout .left-sidebar {
    display: none;
  }
}

/* Mobile: single column, no sidebars */
@media (max-width: 768px) {
  .results-layout {
    grid-template-columns: 1fr;
  }
  .results-layout .left-sidebar,
  .results-layout .right-sidebar {
    display: none;
  }
}

Step 3: Add preferences page layout CSS

/* ============================================================
   Preferences Page Layout
   ============================================================ */

.preferences-layout {
  display: grid;
  grid-template-columns: 200px 1fr;
  gap: 2rem;
  align-items: start;
  padding: 2rem 0;
}

.preferences-nav {
  position: sticky;
  top: calc(var(--header-height) + 1.5rem);
}

.preferences-nav-item {
  display: flex;
  align-items: center;
  gap: 0.6rem;
  padding: 0.6rem 0.75rem;
  border-radius: var(--radius-sm);
  color: var(--text-secondary);
  text-decoration: none;
  font-size: 0.9rem;
  transition: background 0.15s, color 0.15s;
  cursor: pointer;
}

.preferences-nav-item:hover {
  background: var(--bg-tertiary);
  color: var(--text-primary);
}

.preferences-nav-item.active {
  background: var(--accent-soft);
  color: var(--accent);
  font-weight: 500;
}

.preferences-content {
  background: var(--bg);
  border: 1px solid var(--border);
  border-radius: var(--radius-lg);
  padding: 1.5rem;
}

@media (max-width: 768px) {
  .preferences-layout {
    grid-template-columns: 1fr;
  }
  .preferences-nav {
    position: static;
    display: flex;
    overflow-x: auto;
    gap: 0.5rem;
    padding-bottom: 0.5rem;
  }
  .preferences-nav-item {
    white-space: nowrap;
  }
}

Step 4: Add category tiles CSS

/* ============================================================
   Category Tiles
   ============================================================ */

.category-tiles {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(100px, 1fr));
  gap: 1rem;
  margin-top: 2rem;
}

.category-tile {
  display: flex;
  flex-direction: column;
  align-items: center;
  gap: 0.5rem;
  padding: 1rem 0.5rem;
  border-radius: var(--radius-md);
  text-decoration: none;
  color: var(--text-secondary);
  font-size: 0.85rem;
  transition: background 0.15s, color 0.15s, transform 0.15s, box-shadow 0.15s;
}

.category-tile:hover {
  background: var(--bg-tertiary);
  color: var(--text-primary);
  transform: translateY(-2px);
  box-shadow: var(--shadow-sm);
}

.category-tile-icon {
  font-size: 1.5rem;
  line-height: 1;
}

.category-tile.disabled {
  opacity: 0.5;
  cursor: not-allowed;
  pointer-events: none;
}

@media (max-width: 768px) {
  .category-tiles {
    grid-template-columns: repeat(auto-fill, minmax(80px, 1fr));
    gap: 0.75rem;
  }
  .category-tile {
    padding: 0.75rem 0.25rem;
    font-size: 0.75rem;
  }
  .category-tile-icon {
    font-size: 1.25rem;
  }
}

Step 5: Add left sidebar navigation styles

/* ============================================================
   Left Sidebar (Results Page)
   ============================================================ */

.left-sidebar {
  padding: 0;
}

.sidebar-nav {
  display: flex;
  flex-direction: column;
  gap: 0.25rem;
}

.sidebar-nav-title {
  font-size: 0.7rem;
  font-weight: 600;
  text-transform: uppercase;
  letter-spacing: 0.06em;
  color: var(--text-muted);
  padding: 0.5rem 0.75rem;
  margin-top: 0.5rem;
}

.sidebar-nav-item {
  display: flex;
  align-items: center;
  gap: 0.5rem;
  padding: 0.5rem 0.75rem;
  border-radius: var(--radius-sm);
  color: var(--text-secondary);
  text-decoration: none;
  font-size: 0.875rem;
  transition: background 0.15s, color 0.15s;
}

.sidebar-nav-item:hover {
  background: var(--bg-tertiary);
  color: var(--text-primary);
}

.sidebar-nav-item.active {
  background: var(--accent-soft);
  color: var(--accent);
  font-weight: 500;
}

.sidebar-nav-item-icon {
  font-size: 1rem;
  width: 20px;
  text-align: center;
}

.sidebar-filters {
  margin-top: 1rem;
  padding-top: 1rem;
  border-top: 1px solid var(--border);
}

.sidebar-filter-group {
  margin-bottom: 0.75rem;
}

.sidebar-filter-label {
  font-size: 0.75rem;
  font-weight: 500;
  color: var(--text-muted);
  padding: 0 0.75rem;
  margin-bottom: 0.25rem;
}

.sidebar-filter-option {
  display: flex;
  align-items: center;
  gap: 0.5rem;
  padding: 0.35rem 0.75rem;
  font-size: 0.8rem;
  color: var(--text-secondary);
  cursor: pointer;
  border-radius: var(--radius-sm);
  transition: background 0.15s;
}

.sidebar-filter-option:hover {
  background: var(--bg-tertiary);
}

.sidebar-filter-option input[type="radio"] {
  accent-color: var(--accent);
}

/* Mobile filter chips */
.mobile-filter-chips {
  display: none;
  overflow-x: auto;
  gap: 0.5rem;
  padding: 0.75rem 0;
  -webkit-overflow-scrolling: touch;
}

.mobile-filter-chips::-webkit-scrollbar {
  display: none;
}

.mobile-filter-chip {
  display: inline-flex;
  align-items: center;
  padding: 0.4rem 0.75rem;
  border: 1px solid var(--border);
  border-radius: var(--radius-full);
  font-size: 0.8rem;
  color: var(--text-secondary);
  white-space: nowrap;
  text-decoration: none;
  transition: background 0.15s, border-color 0.15s;
}

.mobile-filter-chip:hover,
.mobile-filter-chip.active {
  background: var(--accent-soft);
  border-color: var(--accent);
  color: var(--accent);
}

@media (max-width: 768px) {
  .mobile-filter-chips {
    display: flex;
  }
}

Step 6: Verify Go compilation

Run: go build ./... Expected: No errors

Note: CSS is embedded as static files and not processed by the Go compiler. CSS changes must be tested manually in a browser.

Step 7: Commit

git add internal/views/static/css/kafka.css
git commit -m "feat(frontend): add CSS layout framework for three-column results and preferences page"

PHASE 2: Results Page Three-Column Layout

Task 2: Restructure Results Template

Files:

Modify: internal/views/templates/results.html
Modify: internal/views/views.go
Step 1: Read current results.html to understand exact content

Current structure has .results-layout grid with .search-compact spanning full width, .results-column, and .sidebar. Need to add left sidebar and restructure grid.

Step 2: Replace results.html content

Replace the entire file content:

{{define "title"}}{{if .Query}}{{.Query}} — {{end}}{{end}}
{{define "content"}}
<div class="results-layout">
  <!-- Left Sidebar -->
  <aside class="left-sidebar" id="left-sidebar">
    <nav class="sidebar-nav">
      <div class="sidebar-nav-title">Categories</div>
      {{range .Categories}}
      <a href="/search?q={{$.Query | urlquery}}&category={{.}}" class="sidebar-nav-item {{if eq $.ActiveCategory .}}active{{end}}">
        <span class="sidebar-nav-item-icon">{{index $.CategoryIcons .}}</span>
        <span>{{.}}</span>
      </a>
      {{end}}
    </nav>

    <div class="sidebar-filters">
      <div class="sidebar-filter-group">
        <div class="sidebar-filter-label">Time</div>
        {{range .TimeFilters}}
        <label class="sidebar-filter-option">
          <input type="radio" name="time" value="{{.Value}}" {{if eq $.ActiveTime .Value}}checked{{end}}>
          <span>{{.Label}}</span>
        </label>
        {{end}}
      </div>
      <div class="sidebar-filter-group">
        <div class="sidebar-filter-label">Type</div>
        {{range .TypeFilters}}
        <label class="sidebar-filter-option">
          <input type="radio" name="type" value="{{.Value}}" {{if eq $.ActiveType .Value}}checked{{end}}>
          <span>{{.Label}}</span>
        </label>
        {{end}}
      </div>
    </div>
  </aside>

  <!-- Center Column -->
  <div class="results-column">
    <!-- Compact search bar -->
    <div class="search-compact">
      <div class="search-box">
        <form method="GET" action="/search" role="search" id="search-form">
          <input type="text" name="q" id="q" value="{{.Query}}" autocomplete="off" autofocus
            hx-get="/search" hx-target="#results" hx-trigger="keyup changed delay:500ms" hx-include="this">
          <button type="submit" class="search-box-submit" aria-label="Search">
            <svg width="18" height="18" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2.5" stroke-linecap="round" stroke-linejoin="round">
              <circle cx="11" cy="11" r="8"/>
              <path d="m21 21-4.35-4.35"/>
            </svg>
          </button>
        </form>
      </div>
    </div>

    <!-- Mobile filter chips -->
    <div class="mobile-filter-chips">
      <a href="/search?q={{.Query | urlquery}}" class="mobile-filter-chip {{if not .ActiveCategory}}active{{end}}">All</a>
      {{range .Categories}}
      <a href="/search?q={{$.Query | urlquery}}&category={{.}}" class="mobile-filter-chip {{if eq $.ActiveCategory .}}active{{end}}">{{.}}</a>
      {{end}}
    </div>

    <!-- Results inner -->
    {{template "results_inner" .}}
  </div>

  <!-- Right Sidebar -->
  <aside class="right-sidebar" id="sidebar">
    {{if .Suggestions}}
    <div class="sidebar-card">
      <div class="sidebar-title">Related Searches</div>
      <div class="suggestion-list">
        {{range .Suggestions}}<span class="suggestion"><a href="/search?q={{. | urlquery}}">{{.}}</a></span>{{end}}
      </div>
    </div>
    {{end}}

    {{if .UnresponsiveEngines}}
    <div class="sidebar-card">
      <div class="sidebar-title">Engines with issues</div>
      <ul class="unresponsive-engines">
        {{range .UnresponsiveEngines}}<li>{{index . 0}}: {{index . 1}}</li>{{end}}
      </ul>
    </div>
    {{end}}
  </aside>
</div>
{{end}}

Step 3: Add FilterOption struct and update PageData struct

Add FilterOption struct at package level in views.go (near PageNumber struct):

// FilterOption represents a filter radio option for the sidebar.
type FilterOption struct {
    Label string
    Value string
}

Then update PageData struct to include new fields:

type PageData struct {
    // ... existing fields (SourceURL, Query, Pageno, etc.) ...

    // New fields for three-column layout
    Categories         []string
    CategoryIcons     map[string]string
    DisabledCategories []string
    ActiveCategory    string
    TimeFilters       []FilterOption
    TypeFilters       []FilterOption
    ActiveTime        string
    ActiveType        string
}

Step 4: Update FromResponse signature and body

Update FromResponse signature to accept filter params and set defaults:

func FromResponse(resp contracts.SearchResponse, query string, pageno int, activeCategory, activeTime, activeType string) PageData {
    // Set defaults
    if activeCategory == "" {
        activeCategory = "all"
    }

    pd := PageData{
        // ... existing initialization (NumberOfResults, Results, etc.) ...

        // New: categories with icons
        Categories: []string{"all", "news", "images", "videos", "maps"},
        DisabledCategories: []string{"shopping", "music", "weather"},
        CategoryIcons: map[string]string{
            "all":      "🌐",
            "news":     "📰",
            "images":   "🖼️",
            "videos":   "🎬",
            "maps":     "🗺️",
            "shopping": "🛒",
            "music":    "🎵",
            "weather":  "🌤️",
        },
        ActiveCategory: activeCategory,

        // Time filters
        TimeFilters: []FilterOption{
            {Label: "Any time", Value: ""},
            {Label: "Past hour", Value: "h"},
            {Label: "Past 24 hours", Value: "d"},
            {Label: "Past week", Value: "w"},
            {Label: "Past month", Value: "m"},
            {Label: "Past year", Value: "y"},
        },
        ActiveTime: activeTime,

        // Type filters
        TypeFilters: []FilterOption{
            {Label: "All results", Value: ""},
            {Label: "News", Value: "news"},
            {Label: "Videos", Value: "video"},
            {Label: "Images", Value: "image"},
        },
        ActiveType: activeType,
    }
    // ... rest of function ...
}

Update the Search handler in handlers.go to pass filter params:

pd := views.FromResponse(resp, req.Query, req.Pageno,
    r.FormValue("category"), r.FormValue("time"), r.FormValue("type"))

Step 5: Update results.html sidebar to show disabled state

Update the sidebar category loop to conditionally apply disabled class:

{{range .Categories}}
<a href="/search?q={{$.Query | urlquery}}&category={{.}}" class="sidebar-nav-item {{if eq $.ActiveCategory .}}active{{end}}">
  <span class="sidebar-nav-item-icon">{{index $.CategoryIcons .}}</span>
  <span>{{.}}</span>
</a>
{{end}}
<!-- Disabled categories with no links -->
{{range .DisabledCategories}}
<span class="sidebar-nav-item disabled">
  <span class="sidebar-nav-item-icon">{{index $.CategoryIcons .}}</span>
  <span>{{.}}</span>
</span>
{{end}}

Step 6: Test compilation

Run: go build ./... Expected: No errors

Step 7: Commit

git add internal/views/views.go internal/views/templates/results.html
git commit -m "feat(frontend): add three-column results layout with left sidebar navigation"

PHASE 3: Homepage Category Tiles

Task 3: Add Category Tiles to Homepage

Files:

Modify: internal/views/templates/index.html
Step 1: Read current index.html
Step 2: Replace index.html with tiles

{{define "title"}}{{end}}
{{define "content"}}

{{end}}

Step 2: Add preferences section CSS styles

Append to kafka.css:

/* ============================================================
   Preferences Page Styles
   ============================================================ */

.pref-section {
  margin-bottom: 2rem;
}

.pref-section:last-child {
  margin-bottom: 0;
}

.pref-section-title {
  font-size: 1rem;
  font-weight: 600;
  color: var(--text-primary);
  margin-bottom: 1rem;
  padding-bottom: 0.5rem;
  border-bottom: 1px solid var(--border);
}

.pref-row {
  display: flex;
  align-items: center;
  justify-content: space-between;
  gap: 1rem;
  padding: 0.75rem 0;
  border-bottom: 1px solid var(--border);
}

.pref-row:last-child {
  border-bottom: none;
}

.pref-row label {
  font-size: 0.9rem;
  color: var(--text-primary);
}

.pref-row-info {
  flex: 1;
}

.pref-row-info label {
  font-weight: 500;
}

.pref-desc {
  font-size: 0.8rem;
  color: var(--text-muted);
  margin-top: 0.25rem;
}

.pref-row select {
  padding: 0.5rem 0.75rem;
  font-size: 0.85rem;
  font-family: inherit;
  border: 1px solid var(--border);
  border-radius: var(--radius-sm);
  background: var(--bg);
  color: var(--text-primary);
  cursor: pointer;
  min-width: 150px;
}

.pref-row select:focus {
  outline: none;
  border-color: var(--accent);
}

.pref-row input[type="checkbox"] {
  width: 18px;
  height: 18px;
  accent-color: var(--accent);
  cursor: pointer;
  flex-shrink: 0;
}

.pref-row input[type="checkbox"]:disabled {
  opacity: 0.6;
  cursor: not-allowed;
}

Step 3: Register preferences template in views.go

Add tmplPreferences variable and initialize it in init(). Also add RenderPreferences function:

// In views.go, add to var block:
var (
    tmplFull        *template.Template
    tmplIndex       *template.Template
    tmplFragment    *template.Template
    tmplPreferences *template.Template
)

// In init(), after existing template parsing, add:
tmplPreferences = template.Must(template.New("").Funcs(funcMap).ParseFS(tmplFS,
    "base.html", "preferences.html",
))

// Add RenderPreferences function:
func RenderPreferences(w http.ResponseWriter, sourceURL string) error {
    w.Header().Set("Content-Type", "text/html; charset=utf-8")
    return tmplPreferences.ExecuteTemplate(w, "base", PageData{ShowHeader: true, SourceURL: sourceURL})
}

Step 4: Commit

git add internal/views/templates/preferences.html internal/views/static/css/kafka.css internal/views/views.go
git commit -m "feat(frontend): add preferences page template and styles"

Task 5: Add Preferences Route

Files:

Modify: internal/httpapi/handlers.go
Modify: cmd/kafka/main.go
Step 1: Add GET and POST handlers for /preferences

Add to handlers.go:

// Preferences renders the preferences page.
func (h *Handler) Preferences(w http.ResponseWriter, r *http.Request) {
    if r.URL.Path != "/preferences" {
        http.NotFound(w, r)
        return
    }
    if err := views.RenderPreferences(w, h.sourceURL); err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    }
}

// PreferencesPOST handles form submission from the preferences page.
// NOTE: This is a no-op. All preferences are stored in localStorage on the client
// via JavaScript. This handler exists only for form submission completeness (e.g.,
// if a form POSTs without JS). The JavaScript in settings.js handles all saves.
func (h *Handler) PreferencesPOST(w http.ResponseWriter, r *http.Request) {
    if r.URL.Path != "/preferences" {
        http.NotFound(w, r)
        return
    }
    http.Redirect(w, r, "/preferences", http.StatusFound)
}

Step 2: Register the route in main

Find where routes are registered (likely in cmd/kafka/main.go) and add:

mux.HandleFunc("GET /preferences", handler.Preferences)
mux.HandleFunc("POST /preferences", handler.PreferencesPOST)

Step 3: Test compilation

Run: go build ./... Expected: No errors

Step 4: Commit

git add internal/httpapi/handlers.go cmd/kafka/main.go
git commit -m "feat: add GET and POST /preferences route"

Task 6: Update Settings JavaScript

Files:

Modify: internal/views/static/js/settings.js
Step 1: Reduce popover to theme + engines only

Update the renderPanel function to remove SafeSearch and Format options. Keep only theme buttons and engine toggles.

Step 2: Add preferences page navigation JavaScript

Add to end of settings.js:

// Preferences page navigation
function initPreferences() {
  var nav = document.getElementById('preferences-nav');
  if (!nav) return;

  var sections = document.querySelectorAll('.pref-section');
  var navItems = nav.querySelectorAll('.preferences-nav-item');

  function showSection(id) {
    sections.forEach(function(sec) {
      sec.style.display = sec.id === 'section-' + id ? 'block' : 'none';
    });
    navItems.forEach(function(item) {
      item.classList.toggle('active', item.getAttribute('data-section') === id);
    });
  }

  navItems.forEach(function(item) {
    item.addEventListener('click', function() {
      showSection(item.getAttribute('data-section'));
    });
  });

  // Load saved preferences
  var prefs = loadPrefs();
  var themeEl = document.getElementById('pref-theme');
  if (themeEl) themeEl.value = prefs.theme || 'system';

  var ssEl = document.getElementById('pref-safesearch');
  if (ssEl) ssEl.value = prefs.safeSearch || 'moderate';

  var fmtEl = document.getElementById('pref-format');
  if (fmtEl) fmtEl.value = prefs.format || 'html';

  // Save handlers
  if (themeEl) {
    themeEl.addEventListener('change', function() {
      prefs.theme = themeEl.value;
      savePrefs(prefs);
      applyTheme(prefs.theme);
    });
  }

  if (ssEl) {
    ssEl.addEventListener('change', function() {
      prefs.safeSearch = ssEl.value;
      savePrefs(prefs);
    });
  }

  if (fmtEl) {
    fmtEl.addEventListener('change', function() {
      prefs.format = fmtEl.value;
      savePrefs(prefs);
    });
  }

  // Show first section by default
  showSection('search');
}

document.addEventListener('DOMContentLoaded', initPreferences);

Step 3: Test with browser

Manual verification needed — cannot test browser JS with go build

Step 4: Commit

git add internal/views/static/js/settings.js
git commit -m "feat(frontend): reduce popover to theme+engines, add preferences page JS"

PHASE 5: Polish and Mobile Responsiveness

Task 7: Mobile Filter Chips Integration

Files:

Modify: internal/views/templates/results.html
Step 1: Ensure mobile filter chips have working category links

The current results.html has mobile filter chips with category links. These should preserve existing query params for pagination/HTMX navigation.

Step 2: Add filter form submission via HTMX

Update the filter radio buttons to submit via HTMX when changed.

Step 3: Commit

git add internal/views/templates/results.html
git commit -m "fix(frontend): add HTMX filter submission"

Task 8: Final Mobile Responsiveness Audit

Files:

Review: internal/views/static/css/kafka.css
Step 1: Test all breakpoints manually
Step 2: Fix any layout issues found
Step 3: Commit any fixes

git add internal/views/static/css/kafka.css
git commit -m "fix(frontend): improve mobile responsiveness"
