## 🚀 Quick Start - How to Add to All Pages

### Step 1: Add CSS Links to Your Page Head
```html
<head>
    <!-- Responsive Utilities -->
    <link rel="stylesheet" href="assets/css/responsive-utilities.css">
    
    <!-- Live Chat Styles -->
    <link rel="stylesheet" href="assets/css/responsive-chat.css">
    
    <!-- FontAwesome Icons (if not already included) -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css">
</head>
```

### Step 2: Add Chat Widget Before Closing Body Tag
```html
<body>
    <!-- Your page content here -->
    
    <!-- Include Chat Widget -->
    <?php include 'includes/chat-widget.html'; ?>
    
    <!-- Chat Script -->
    <script src="assets/js/responsive-chat.js"></script>
</body>
```

### Step 3: Use Responsive Utility Classes

#### Typography
```html
<!-- Fluids sizes that scale with viewport -->
<h1>This heading scales automatically</h1>
<p>This paragraph adjusts font size responsively</p>
```

#### Grid System
```html
<div class="grid grid-cols-3">
    <!-- Automatically becomes 1 col on mobile, 3 on desktop -->
    <div class="card">Item 1</div>
    <div class="card">Item 2</div>
    <div class="card">Item 3</div>
</div>
```

#### Flexbox Utilities
```html
<div class="flex flex-between">
    <!-- Flex layout with space-between -->
    <div>Left</div>
    <div>Right</div>
</div>
```

#### Responsive Spacing
```html
<div class="p-3 m-2">
    <!-- Padding and margin scale responsively -->
</div>
```

#### Buttons
```html
<button class="btn btn-primary">Click Me</button>
<!-- Min height 44px, responsive padding and font size -->
```
