Implementing a chatbot in a web application.
See below how we can implement a chatbot in a web application using HTML, CSS, JavaScript and a simple backend server (in this case, we'll use Node.js with Express.js). **html** ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Chatbot Example</title> <link rel="stylesheet" href="styles.css"> </head> <body> <div id="chat-container"> <div id="chat-display"></div> <input type="text" id="user-input" placeholder="Type your message..."> <button onclick="sendMessage()">Send</button> </div> <script src="script.js"></script> </body> </html> ``` **css** ```css #chat-container { width: 300px; margin: auto; padding: 20px; border: 1px solid #ccc; border-radius: 5px; } #chat-display { height: 300px; overflow-y: auto; margin-bottom: 10px; border: 1px solid #ccc; padding: 10px; } #user-input { width: calc(100% - 70px); padding: 8px; margin-right: 5px; } button { padding: 8px 15px; } ``` **Javascript logic** ```js const chatDisplay = document.getElementById("chat-display"); const userInput = document.getElementById("user-input"); function sendMessage() { const userMessage = userInput.value; displayMessage(userMessage, "user"); userInput.value = ""; // Simulate response from the bot setTimeout(() => { const botResponse = "This is a sample bot response."; displayMessage(botResponse, "bot"); }, 500); } function displayMessage(message, sender) { const messageElement = document.createElement("div"); messageElement.classList.add(sender); messageElement.innerText = message; chatDisplay.appendChild(messageElement); } ``` **Backend Server (server.js) (This requires Node.js and Express.js)**: ```js const express = require('express'); const app = express(); const port = 3000; app.use(express.static('public')); app.listen(port, () => { console.log(`Server is running on http://localhost:${port}`); }); ``` Make sure to have Node.js and Express.js installed. You can install Express.js using npm: ```bash npm install express ``` This is just a basic example to get you started. Depending on your requirements, you may want to integrate with a more sophisticated backend or use a pre-built chatbot platform like Dialogflow or Microsoft Bot Framework.
yay i got a friend now
