# KSO CHD Logo Implementation Guide

## Overview
The KSO Chandigarh Management System now includes logo support across all major interfaces. The logo is implemented with fallback functionality to ensure the system works even if the actual logo image is not available.

## Logo Implementation Details

### 1. Logo File Location
- **Path**: `img/kso-logo.png`
- **Current Status**: Placeholder file with specifications
- **Recommended Format**: PNG or SVG
- **Recommended Size**: 120x40 pixels or larger
- **Background**: Transparent or white

### 2. Fallback System
The system includes a robust fallback mechanism:
- **Primary**: Attempts to load the actual logo image
- **Fallback**: If image fails to load, displays a circular "KSO" badge
- **Styling**: Consistent with the KSO brand colors (#4e73df)

### 3. Implementation Locations

#### A. Main Landing Page (`index.php`)
- **Location**: Main navigation bar
- **Size**: 35x35 pixels
- **Style**: Dark theme compatible
- **Fallback**: Circular badge with "KSO" text

#### B. Member Dashboard (`includes/topbar.php`)
- **Location**: Member interface topbar
- **Size**: 40x40 pixels
- **Style**: Light theme with brand text
- **Fallback**: Circular badge with "KSO" text

#### C. Admin Dashboard (`admin/includes/topbar.php`)
- **Location**: Admin interface topbar
- **Size**: 40x40 pixels
- **Style**: Light theme with "Admin Panel" text
- **Fallback**: Circular badge with "KSO" text

### 4. HTML Structure
```html
<div class="d-flex align-items-center">
  <div class="mr-3" style="height: 40px; width: 40px; display: flex; align-items: center; justify-content: center;">
    <img src="img/kso-logo.png" alt="KSO CHD Logo" style="height: 100%; width: auto; max-width: 100%;" 
         onerror="this.style.display='none'; this.nextElementSibling.style.display='flex';">
    <div style="display: none; height: 40px; width: 40px; background: #4e73df; border-radius: 50%; 
                align-items: center; justify-content: center; color: white; font-weight: bold; font-size: 12px;">
      KSO
    </div>
  </div>
  <div>
    <h5 class="text-primary mb-0 font-weight-bold">KSO Chandigarh</h5>
    <small class="text-muted">Management System</small>
  </div>
</div>
```

### 5. CSS Styling
The logo implementation uses inline styles for consistency:
- **Container**: Flexbox layout for alignment
- **Logo Image**: Responsive sizing with max-width constraint
- **Fallback Badge**: Circular design with brand colors
- **Text**: Hierarchical typography with brand colors

### 6. JavaScript Fallback
The `onerror` attribute handles image loading failures:
```javascript
onerror="this.style.display='none'; this.nextElementSibling.style.display='flex';"
```
