# Template Display & UI/UX Fix - Complete

## Summary
Fixed template display issues and improved UI/UX by moving Templates from left panel to top navigation as a full-screen modal.

## Changes Made

### 1. **index.html**

#### Added Templates button to top navigation (between Clear and Export)
```html
<button id="btn-templates" class="nav-btn" title="Templates">
    <svg>...</svg>
    <span>Templates</span>
</button>
<span class="divider"></span>
```

#### Removed Templates tab from left panel
- Removed: `<button class="panel-tab" data-panel="templates">Templates</button>`
- Now only 4 tabs: Blocks, Pages, Layers, Assets (no horizontal scrollbar)

#### Removed templates container from left panel
- Deleted entire `<div id="templates-container">` section

#### Added new full-screen Templates Browser Modal
```html
<div id="templates-browser-modal" class="modal-overlay">
    <div class="modal export-modal">
        <!-- Template browser with filters and grid -->
    </div>
</div>
```

### 2. **js/editor.js**

#### Updated panel switching logic
- Removed `templates-container` display handling
- Now only handles: blocks, pages, layers, assets

#### Added Templates Browser Modal handlers
```javascript
// Open/close modal functions
function openTemplatesBrowser() { ... }
function closeTemplatesBrowser() { ... }

// Event listeners
- Click #btn-templates → opens modal
- Click close button → closes modal
- Click outside modal → closes modal
- Press ESC key → closes modal
```

#### Improved template loading
- Added `closeTemplatesBrowser()` call after template confirmation
- Better error handling with HTTP status checks
- Enhanced console logging for debugging

#### Enhanced error messages
- Better error display in template grid
- Detailed console logging for fetch failures
- User-friendly error alerts with context

### 3. **css/editor.css**

#### Modal styling for templates browser
```css
#templates-browser-modal .modal {
    width: 80vw;
    max-width: 1200px;
    max-height: 85vh;
}
```

#### Updated templates grid for modal layout
```css
.templates-grid {
    grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
    gap: 16px;
    padding: 20px 0;
}
```

#### Fixed modal-overlay display handling
- Changed from `opacity/visibility` to `display: none/flex`
- Simplified modal show/hide logic

## Files Modified
1. `/home/jknapp/code/site-builder/index.html`
2. `/home/jknapp/code/site-builder/js/editor.js`
3. `/home/jknapp/code/site-builder/css/editor.css`

## Design Pattern
Follows existing export modal pattern:
- Full-screen overlay with dark backdrop
- Large modal centered on screen
- ESC key / outside click to close
- Smooth transitions
- Consistent styling with rest of app

## Benefits
1. **No horizontal scrollbar** - Left panel now fits comfortably
2. **Better template browsing** - Large grid view with more space
3. **Clean interface** - Less crowded left panel
4. **Consistent UX** - Matches export modal pattern
5. **Easier template selection** - Full-screen view shows more templates at once
6. **Better error handling** - Users know when/why things fail

## Notes
- Templates load via fetch() which works fine with http:// and https://
- For file:// protocol testing, use `python3 -m http.server` or similar
- Template thumbnails fallback to colored background if SVG missing
- All 8 templates in templates/index.json display correctly
