8. Introduction to the Document Object Model (DOM)

The DOM is a crucial concept in web development. You will learn about the DOM tree structure and how nodes and elements relate to each other. We will cover how to access and traverse the DOM using JavaScript, and the role of the window and document objects. This section will provide you with the foundation to manipulate web pages dynamically.

9. Manipulating the DOM with JavaScript

Building on your understanding of the DOM, this section will teach you how to select elements by ID, class, and tag, and use querySelector() and querySelectorAll(). You will learn how to change element content, update attributes, and modify styles directly. We will cover adding and removing classes, creating and appending new elements, and removing elements from the DOM. You will also learn about cloning nodes and working with templates.

10. Adding Interactivity with JavaScript

Interactivity is what makes web pages engaging. You will learn about events and event-driven programming, and how to attach event listeners and handlers. We will cover mouse events, keyboard events, form events, and timing events. You will learn how to change content based on user interaction, implement show/hide functionality, and create modal dialogs. By the end of this section, you will be able to enhance user experience with dynamic features.

11. Events and Event Handling

This section delves deeper into event handling. You will explore the event object and understand event propagation, including bubbling and capturing phases. We will cover preventing default behavior, event delegation, and handling multiple events. You will also learn about custom events, touch and gesture events, drag and drop interactions, and techniques like debouncing and throttling. This section will equip you with the skills to write efficient and maintainable event-driven code.

12. Building a Simple Interactive Web Page

It’s time to bring everything together and build a simple interactive web page. We will outline the project features and goals, design the layout, and create the HTML structure. You will apply CSS styles and add interactivity with JavaScript. We will cover working with forms, implementing a slider or carousel, incorporating media elements, and testing across different browsers. By the end of this section, you will have a fully functional web page that you can showcase.

13. Debugging and Troubleshooting

Debugging is an essential skill for any developer. You will learn how to identify and fix common HTML and CSS errors, and debug JavaScript code using breakpoints and console methods. We will cover analyzing network activity, error handling, and validating code with linters. You will also learn about performance profiling, resolving compatibility issues, and reading documentation and error messages. This section will provide you with strategies to streamline the debugging process.

14. Best Practices and Accessibility

Writing clean and accessible code is crucial for creating inclusive web experiences. You will learn about writing semantic HTML, organizing files and folders, and commenting and documenting your code. We will cover enhancing accessibility, SEO fundamentals, responsive and mobile-first design, and optimizing performance. You will also learn about security considerations and keeping your code DRY (Don’t Repeat Yourself). By the end of this section, you will be equipped with best practices for web development.
