Chat bots are computer programs designed to simulate human conversation with users through text or voice interactions. They have gained popularity in various applications and industries due to their ability to automate tasks, provide customer support, and enhance user experiences. Here's a summary of key points about chat bots:
Definition: Chat bots are artificial intelligence (AI) or machine learning programs that can engage in conversation with users. They can understand and generate human-like responses.
Types: Rule-Based Chat bots: These follow predefined rules and responses, suitable for handling simple and structured interactions. AI-Powered Chat bots: These use natural language processing (NLP) and machine learning to understand and respond to more complex user inputs.
Step 1: Create a New Folder Create a new folder on your computer to organize your project files called Chat-Bot.
Step 2: Create an HTML File Inside your project folder, create a new file with the ".html" extension.
Step 3: Set Up the HTML Structure In your HTML file, set up the boiler plate:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Simple Chatbot</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<!-- Your content goes here -->
<script src="script.js"></script>
</body>
</html>Step 4: Setup HTML
1. Create a `div` element with a class of `container`.
2. Inside the `container` div, create another `div` element with a class of `chat-header`, and set the text content to "Simple Chatbot."
3. Close the `chat-header` div.
4. Add another `div` element inside the `container` div with a class of `chat-box` and an `id` of `chat-box`.
5. Inside the `chat-box` div, create another `div` element with a class of `chat-message` and `bot`, and add the desired content for your initial bot message.
6. Close the `chat-message` div and then close the `chat-box` div.
7. Include another `div` element inside the `container` div with a class of `chat-input`.
8. Inside the `chat-input` div, create an `input` element with the `type` set to "text," an `id` of "user-input," and a `placeholder` attribute set to "Type a message..."
9. After the `input` element, add a `button` element with an `id` of "send-button," and set the button text to "Send."
10. Close chat-input and chat-container div.
Create a New CSS: Save the file with a ".css" extension, for example, "styles.css". Make sure you save it in a location you can easily access later.
