## 2. Setting Up Your Environment – web development with HTMX
Before we dive into coding, let’s set up our development environment.

**Prerequisites**
- Basic understanding of HTML and CSS
- A code editor (e.g., VS Code)
- A web server (e.g., XAMPP, MAMP, or a simple Python HTTP server)

## Installation
You can include HTMX in your project by adding the following CDN link to your HTML file:
```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>HTMX Tutorial</title>
    <script src="https://unpkg.com/htmx.org@1.8.4"></script>
</head>
<body>
    <!-- Your content here -->
</body>
</html>
```
**Alternatively, you can download HTMX and host it locally in your project.**

## 3. Basic HTMX Concepts – web development with HTMX
HTMX extends HTML with several powerful attributes that make it easy to add interactivity. Let’s explore some of the core concepts:

## hx-get
The hx-get attribute triggers an AJAX GET request when an event occurs (e.g., a click).
```html
<button hx-get="/example" hx-target="#result">Load Content</button>
<div id="result"></div>
```

## hx-post
The hx-post attribute triggers an AJAX POST request.
```html
<form hx-post="/submit" hx-target="#result">
    <input type="text" name="data" required>
    <button type="submit">Submit</button>
</form>
<div id="result"></div>
```

## hx-target
The hx-target attribute specifies the element where the response will be rendered.

## hx-trigger
The hx-trigger attribute defines the event that triggers the request.
```html
<input hx-trigger="keyup changed delay:500ms" hx-get="/suggestions" hx-target="#suggestions">
<div id="suggestions"></div>
```

## hx-swap
The hx-swap attribute determines how the response content is swapped into the target element.
```html
<button hx-get="/example" hx-target="#result" hx-swap="outerHTML">Replace Content</button>
<div id="result">Original Content</div>
```
