Creating a working chatbox using HTML, CSS, and JavaScript involves integrating all three technologies to enable user interaction and dynamic content display. Here's a comprehensive example demonstrating how to achieve this:

### HTML Structure:
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Chatbox</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <div class="chat-container" id="chat-container">
    <div class="chat-box" id="chat-box">
      <div class="chat-message bot">Hello! How can I assist you today?</div>
    </div>
    <input type="text" id="user-input" placeholder="Type your message...">
    <button id="send-button">Send</button>
  </div>
  <script src="script.js"></script>
</body>
</html>

    <button id="send-button">Send</button>
  </div>
  <script src="script.js"></script>
</body>
</html>


### CSS (styles.css):
body {
  font-family: Arial, sans-serif;
  background-color: #f4f4f4;
  margin: 0;
  padding: 0;
}

.chat-container {
  max-width: 400px;
  margin: 50px auto;
  padding: 20px;
  background-color: #fff;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
  border-radius: 8px;
}

.chat-box {
  max-height: 300px;
  overflow-y: auto;
  padding: 10px;
}

.chat-message {
  margin-bottom: 10px;
  padding: 10px;
  border-radius: 8px;
}

.chat-message.bot {
  background-color: #e0e0e0;
}

input[type="text"] {
  width: 70%;
  padding: 10px;
  margin-right: 10px;
  border: 1px solid #ccc;
  border-radius: 4px;
}

button {
  padding: 10px 20px;
  border: none;
  background-color: #007bff;
  color: #fff;
  border-radius: 4px;
  cursor: pointer;
}


### JavaScript (script.js):
document.getElementById('send-button').addEventListener('click', function() {
  sendMessage();
});

document.getElementById('user-input').addEventListener('keypress', function(e) {
  if (e.key === 'Enter') {
    sendMessage();
  }
});

function sendMessage() {
  const userInput = document.getElementById('user-input').value;
  if (userInput) {
    addUserMessage(userInput);
    // Process user input and generate bot response (you can integrate your existing chatbot logic here)
    const botResponse = generateBotResponse(userInput);
    addBotMessage(botResponse);
    document.getElementById('user-input').value = ''; // Clear the input field after sending the message
  }
}

function addBotMessage(message) {
  const chatBox = document.getElementById('chat-box');
  const botMessage = document.createElement('div');
  botMessage.className = 'chat-message bot';
  botMessage.textContent = message;
  chatBox.appendChild(botMessage);
  chatBox.scrollTop = chatBox.scrollHeight; // Automatically scroll to the bottom of the chat box
}

function addUserMessage(message) {
  const chatBox = document.getElementById('chat-box');
  const userMessage = document.createElement('div');
  userMessage.className = 'chat-message user';
  userMessage.textContent = message;
  chatBox.appendChild(userMessage);
  chatBox.scrollTop = chatBox.scrollHeight; // Automatically scroll to the bottom of the chat box
}

function generateBotResponse(userInput) {
  // Your logic for generating bot response goes here
  return "This is a sample bot response.";
}


In this example, the HTML provides the basic structure of the chatbox, the CSS styles the layout and appearance, and the JavaScript handles user input, bot responses, and chat message display. You can customize the appearance and functionality according to your specifications and integrate your existing chatbot logic within the generateBotResponse function.

About HTML

HTML(Hyper Text Markup language) is the standard markup language for Web pages, was created by Berners-Lee in the year 1991. Almost every web page over internet might be using HTML.

Syntax help

Fundamentals

  • Any HTML document must start with document declaration <!DOCTYPE html>
  • HTML documents begin with <html> and ends with </html>
  • Headings are defined with <h1> to <h6> where <h1> is the highest important heading and <h6> is the least important sub-heading.
  • Paragrahs are defined in <p>..</p> tag.
  • Links are defined in <a> tag.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>
  • Images are defined in <img> tag, where src attribute consists of image name.
  • Buttons are defined in <button>..</button> tag
  • Lists are defined in <ul> for unordered/bullet list and <ol> for ordered/number list, and the list items are defined in <li>.

HTML Elements and Attributes

  • HTML element is everything present from start tag to end tag.
  • The text present between start and end tag is called HTML element content.
  • Anything can be a tagname but it's preferred to put the meaningful title to the content present as tag name.
  • Do not forget the end tag.
  • Elements with no content are called empty elements.
  • Elements can have attributes which provides additional information about the element.
  • In the below example, href is an attribute and a is the tag name.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>

CSS

CSS(cascading style sheets) describes how HTML elements will look on the web page like color, font-style, font-size, background color etc.

Example:

Below is a sample style sheet which displays heading in green and in Candara font with padding space of 25px.

body{
  padding: 25px;
}
.title {
	color: #228B22;
	font-family: Candara;
}

HTML Tables

  • HTML Tables are defined in <table> tag.
  • Table row should be defined in <tr> tag
  • Table header should be defined in <th> tag
  • Table data should be defined in <td> tag
  • Table caption should be defined in <caption> tag

HTML-Javascript

  • Javascript is used in HTML pages to make them more interactive.
  • <script> is the tag used to write scripts in HTML
  • You can either reference a external script or write script code in this tag.

Example

<script src="script.js"></script>
