Date: November 26, 2025
Reference: STORE_UI_UX_GUIDE.md
Status: Implemented & Ready for Testing

---

📋 Implementation Summary

Successfully rebuilt the product page following the STORE_UI_UX_GUIDE.md standards, incorporating lessons from Tokopedia, Shopify, Amazon, and UX research.

---

✅ What Was Implemented

1. Typography Hierarchy (FIXED)

Before:

Price: 48-60px (TOO BIG)
Title: 24-32px

After (per UI/UX Guide):

Title: 28-32px (PRIMARY)
Price: 24px (SECONDARY)

Rationale: We're not a marketplace (like Tokopedia). Title should be primary hierarchy.

---

2. Image Gallery

Desktop:

┌─────────────────────────────────────┐
│        [Main Image]                 │
│        (object-contain, padding)    │
└─────────────────────────────────────┘
[▭] [▭] [▭] [▭] [▭] ← Thumbnails (96-112px)

Features:

• ✅ Thumbnails: 96-112px (w-24 md:w-28)
• ✅ Horizontal scrollable
• ✅ Arrow navigation if >4 images
• ✅ Active thumbnail: Primary border + ring-4
• ✅ Click thumbnail → change main image

Mobile:

┌─────────────────────────────────────┐
│        [Main Image]                 │
│         ● ○ ○ ○ ○                   │
└─────────────────────────────────────┘

Features:

• ✅ Dots only (NO thumbnails)
• ✅ Active dot: Primary color, elongated (w-6)
• ✅ Inactive dots: Gray (w-2)
• ✅ Click dot → change image
• ✅ Swipe gesture supported (native)

Rationale: Convention (Amazon, Tokopedia, Shopify all use dots only on mobile)

---

3. Variation Selectors (PILLS)

Before:

<select>
  <option>Choose Color</option>
  <option>Black</option>
  <option>White</option>
</select>

After:

<div class="flex flex-wrap gap-2">
  <button class="min-w-[44px] min-h-[44px] px-4 py-2 rounded-lg border-2">
    Black
  </button>
  <button class="min-w-[44px] min-h-[44px] px-4 py-2 rounded-lg border-2">
    White
  </button>
</div>

Features:

• ✅ All options visible at once
• ✅ Pills: min 44x44px (touch target)
• ✅ Active state: Primary background + white text
• ✅ Hover state: Border color change
• ✅ No dropdowns (better UX)

Rationale: Convention + Research align (Nielsen Norman Group)

---

4. Product Information Sections

Pattern: Vertical Accordions (NOT Horizontal Tabs)

┌─────────────────────────────────────┐
│ ▼ Product Description               │ ← Auto-expanded
│   Full description text...          │
└─────────────────────────────────────┘
┌─────────────────────────────────────┐
│ ▶ Specifications                    │ ← Collapsed
└─────────────────────────────────────┘
┌─────────────────────────────────────┐
│ ▶ Customer Reviews                  │ ← Collapsed
└─────────────────────────────────────┘

Features:

• ✅ Description: Auto-expanded on load
• ✅ Other sections: Collapsed by default
• ✅ Arrow icon: Rotates on expand/collapse
• ✅ Smooth animation
• ✅ Full-width clickable header

Rationale: Research (Baymard: 27% overlook horizontal tabs, only 8% overlook vertical)

---

5. Specifications Table

Pattern: Scannable Two-Column Table

┌─────────────────────────────────────┐
│ Material      │ 100% Cotton         │
│ Weight        │ 250g                │
│ Color         │ Black, White, Gray  │
└─────────────────────────────────────┘

Features:

• ✅ Label column: Bold, gray background
• ✅ Value column: Regular weight
• ✅ Padding: py-4 px-6
• ✅ Border: Bottom border on each row

Rationale: Research (scannable > plain table)

---

6. Buy Section

Structure:

1. Product Title (H1) - PRIMARY
2. Price - SECONDARY (not overwhelming)
3. Stock Status (badge with icon)
4. Short Description
5. Variation Selectors (pills)
6. Quantity Selector
7. Add to Cart (prominent CTA)
8. Wishlist Button
9. Trust Badges
10. Product Meta

Features:

• ✅ Title: text-2xl md:text-3xl

• ✅ Stock badge: Inline-flex with icon
• ✅ Pills: 44x44px minimum
• ✅ Add to Cart: h-14, full width
• ✅ Trust badges: 3 items (shipping, returns, secure)

🔧 Technical Implementation

Key Components:

// State management
const [selectedImage, setSelectedImage] = useState<string>();
const [selectedVariation, setSelectedVariation] = useState<any>(null);
const [selectedAttributes, setSelectedAttributes] = useState<Record<string, string>>({});
const [quantity, setQuantity] = useState(1);
const [activeTab, setActiveTab] = useState<'description' | 'additional' | 'reviews' | ''>('description');

// Image navigation
const thumbnailsRef = useRef<HTMLDivElement>(null);
const scrollThumbnails = (direction: 'left' | 'right') => { ... };

// Variation handling
const handleAttributeChange = (attributeName: string, value: string) => { ... };

// Auto-switch variation image
useEffect(() => {
  if (selectedVariation && selectedVariation.image) {
    setSelectedImage(selectedVariation.image);
  }
}, [selectedVariation]);

CSS Utilities:

/* Hide scrollbar */
.scrollbar-hide::-webkit-scrollbar { display: none; }
.scrollbar-hide { -ms-overflow-style: none; scrollbar-width: none; }

/* Responsive visibility */
.hidden.md\\:block { display: none; }
@media (min-width: 768px) { .hidden.md\\:block { display: block; } }

/* Image override */
.\\!h-full { height: 100% !important; }

🎯 Key Decisions Made

1. Dots vs Thumbnails on Mobile

• Decision: Dots only (no thumbnails)
• Rationale: Convention (Amazon, Tokopedia, Shopify)
• Evidence: User screenshot of Amazon confirmed this

2. Pills vs Dropdowns

• Decision: Pills/buttons
• Rationale: Convention + Research align
• Evidence: Nielsen Norman Group guidelines

3. Title vs Price Hierarchy

• Decision: Title > Price
• Rationale: Context (we're not a marketplace)
• Evidence: Shopify (our closer analog) does this

4. Tabs vs Accordions

• Decision: Vertical accordions
• Rationale: Research (27% overlook tabs)
• Evidence: Baymard Institute study

5. Description Auto-Expand

• Decision: Auto-expanded on load
• Rationale: Don't hide primary content
• Evidence: Shopify does this
