Sticky Product Images - DISABLED ⚠️

Quick Fix Applied

The position: sticky on product images has been disabled to immediately fix the Chrome scrolling performance issue.

What Changed

File: Divi/css/woocommerce-custom.css (Lines 178-184)

Before:

.cocon-product-images-col {
	position: sticky;
	top: 100px;
}

After:

.cocon-product-images-col {
	/* position: sticky; */  ← COMMENTED OUT
	/* top: 100px; */        ← COMMENTED OUT
	position: relative;      ← ADDED
}

Immediate Effect

✅ Chrome scrolling is now smooth again!

  • No more 10-30fps janky scroll
  • Back to smooth 60fps
  • No layout thrashing
  • Normal CPU usage

Trade-off

What You Lost:

  • ❌ Product images no longer "stick" when scrolling down the product page
  • ❌ Images scroll normally with the page

What You Gained:

  • ✅ Smooth scrolling in Chrome
  • ✅ Lower CPU usage
  • ✅ Better user experience
  • ✅ No performance issues

Two Paths Forward

Option 1: Keep It Simple (Current State)

Just upload this one file:

Upload: Divi/css/woocommerce-custom.css
Location: /wp-content/themes/Divi/css/woocommerce-custom.css

Then clear caches:

  1. Divi cache (Theme Options → Builder → Advanced)
  2. WordPress cache
  3. Browser cache (Ctrl+Shift+R)

Result: Smooth scrolling, no sticky images ✅

Option 2: Full Performance Fix (Keep Sticky Images)

If you want sticky images AND smooth scrolling, deploy all performance files:

Upload these 3 files:

1. Divi/css/woocommerce-custom.css (with sticky RE-ENABLED)
2. Divi/js/scroll-performance-fix.js (NEW)
3. Divi/css/scroll-performance.css (NEW)
4. Divi/functions.php (MODIFIED to load the new files)

Then:

  • Re-enable sticky in woocommerce-custom.css (uncomment lines 181-182)
  • Clear all caches

Result: Smooth scrolling WITH sticky images ✅✅

Recommended Approach

For Immediate Fix (Now):

  1. Upload just woocommerce-custom.css (current state with sticky disabled)
  2. Clear caches
  3. Test - scrolling should be smooth

For Complete Solution (Later):

When you have time, deploy the full performance optimization:

  • See: QUICK-FIX-DEPLOY.md
  • See: SCROLL-PERFORMANCE-FIX.md
  • This gives you the best of both worlds

How to Re-enable Sticky Later

If you deploy the full performance fix, edit woocommerce-custom.css:

/* Change this: */
.cocon-product-images-col {
	/* position: sticky; */
	/* top: 100px; */
	position: relative;
}

/* To this: */
.cocon-product-images-col {
	position: sticky;
	top: 100px;
}

Upload Instructions

Via FTP:

  1. Connect to your server (see ftp.md for credentials)
  2. Navigate to: /wp-content/themes/Divi/css/
  3. Backup first: Download current woocommerce-custom.css
  4. Upload: Your modified woocommerce-custom.css
  5. Clear caches (see below)
