# 📱 MOBILE SCROLLING ISSUE FIXED

## ✅ **PROBLEM RESOLVED**

### **🔍 Issue Identified:**
The mobile website was experiencing automatic scrolling to the top when users tried to scroll down, causing a frustrating user experience where the page would repeatedly jump back to the top.

### **🕵️ Root Causes Found:**
1. **Mobile Menu Overflow Conflicts** - Menu script was setting `body.style.overflow = 'hidden'` improperly
2. **Missing Touch Scrolling Support** - `-webkit-overflow-scrolling: touch` not properly implemented
3. **Scroll Restoration Issues** - Browser auto-restoring scroll position inappropriately
4. **Event Handler Conflicts** - Touch events potentially interfering with natural scrolling
5. **Viewport Issues** - Improper mobile viewport handling causing layout shifts

### **🛠️ COMPREHENSIVE FIXES APPLIED:**

#### **1. CSS Fixes in header.php & index.php:**
```css
/* Mobile Touch Scrolling */
html, body {
    -webkit-overflow-scrolling: touch !important;
    overflow-scrolling: touch !important;
    position: relative !important;
}

/* Prevent Touch Issues */
* {
    -webkit-tap-highlight-color: transparent;
    -webkit-touch-callout: none;
}

/* Re-enable Text Selection */
p, span, div, h1, h2, h3, h4, h5, h6, li, a {
    -webkit-user-select: text;
    user-select: text;
}
```

#### **2. Mobile Menu JavaScript Fixes:**
```javascript
// Improved overflow handling with delays
if (isActive) {
    // Close menu with delayed overflow reset
    setTimeout(() => {
        document.body.style.overflow = '';
        document.body.style.position = '';
        document.documentElement.style.overflow = '';
    }, 100);
} else {
    // Open menu with proper body fixing
    document.body.style.overflow = 'hidden';
    document.body.style.position = 'fixed';
    document.body.style.width = '100%';
}
```

#### **3. Mobile Scrolling JavaScript Fixes:**
```javascript
// Disable problematic scroll restoration
if ('scrollRestoration' in history) {
    history.scrollRestoration = 'manual';
}

// Ensure proper touch scrolling
document.body.style.webkitOverflowScrolling = 'touch';

// Fix viewport height for mobile browsers
const vh = window.innerHeight * 0.01;
document.documentElement.style.setProperty('--vh', `${vh}px`);
```

#### **4. Passive Event Listeners:**
```javascript
// Use passive listeners to prevent scroll blocking
window.addEventListener('scroll', function() {
    // Handle scroll events
}, { passive: true });

document.addEventListener('touchstart', function(e) {
    // Handle touch without preventing default
}, { passive: true });
```
