**Course Title:** HTML & Web Development Fundamentals: Building Modern Websites **Section Title:** HTML and JavaScript Integration **Topic:** Build a simple interactive webpage using JavaScript to modify HTML elements.(Lab topic) **Introduction:** In this lab, we will put your HTML and JavaScript skills to the test by building a simple interactive webpage that uses JavaScript to modify HTML elements. By the end of this lab, you will have hands-on experience with JavaScript's power to dynamically alter web pages. **Project Overview:** For this lab, you will build a simple webpage that allows users to interact with it using JavaScript. The webpage will display a header with a button that, when clicked, will: 1. Change the background color of the webpage. 2. Change the font size of the paragraph. 3. Display a hidden message. **Step 1: Create the HTML structure** First, create a new HTML file and add the following basic structure: ```html <!DOCTYPE html> <html> <head> <title>Interactive Webpage</title> </head> <body> <!-- Add HTML elements here --> <script src="script.js"></script> </body> </html> ``` Create a new JavaScript file (`script.js`) in the same directory and link it to the HTML file using the `<script>` tag. **Step 2: Create the HTML elements** Add the following HTML elements to the `<body>`: ```html <header> <h1>Interactive Webpage</h1> <button id="interact-button">Interact</button> </header> <p id="paragraph">This is a paragraph of text.</p> <p id="hidden-message" style="display: none;">Hello, World!</p> ``` **Step 3: Add JavaScript event listener** In the `script.js` file, add an event listener to the button with the id `interact-button`: ```javascript document.getElementById('interact-button').addEventListener('click', function() { // Add JavaScript code here to modify HTML elements }); ``` **Step 4: Modify HTML elements using JavaScript** Inside the event listener, add the following JavaScript code to modify the HTML elements: ```javascript // Change the background color of the webpage document.body.style.background = 'lightblue'; // Change the font size of the paragraph document.getElementById('paragraph').style.fontSize = '24px'; // Display the hidden message document.getElementById('hidden-message').style.display = 'block'; ``` **Complete the Project:** Save both the HTML and JavaScript files and open the HTML file in a web browser. Click the button to see the interactive effects. **Practical Takeaways:** * You can use JavaScript to dynamically modify HTML elements. * The `addEventListener` method is used to attach an event listener to an HTML element. * You can use the `style` property to change the styles of HTML elements using JavaScript. **Example Use Case:** You can use this technique to create interactive web pages that respond to user input. For example, you can use JavaScript to change the background color of a webpage based on the user's selection from a dropdown list. **Tips and Variations:** * Try changing the background color to a different color or gradient. * Add more HTML elements to interact with using JavaScript. * Use different JavaScript methods to modify the HTML elements, such as `innerHTML` or `classList`. **Conclusion:** In this lab, you have successfully built a simple interactive webpage that uses JavaScript to modify HTML elements. You can apply this technique to create more complex and dynamic web pages. **What's Next:** In the next topic, 'Creating interactive content with `<details>` and `<summary>` elements', we will explore more advanced HTML techniques for creating interactive content. **Leave a Comment or Ask for Help:** If you have any questions or need help with this lab, please leave a comment below. **Recommended Resources:** * Mozilla Developer Network: [HTMLElement: addEventListener](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/addEventListener) * W3Schools: [JavaScript: addEventListener](https://www.w3schools.com/jsref/met_element_addeventlistener.asp)
