  • Lesson 4 • HTML Document Anatomy

    Explains doctype, head, and body sections and their roles. Grounds students in the document object model before any styling or scripting is introduced.

  • Lesson 5 • HTML Forms and Input Types

    Covers form structure, input types, labels, and validation attributes. Prepares students for JavaScript form handling introduced in Chapter 4.

Chapter 3See details

CSS Styling and Layout

    Teaches font properties, web fonts, and colour models including hex, RGB, and HSL. Connects visual design principles to CSS implementation.

  • Lesson 2 • Responsive Design and Media Queries

    Applies breakpoints, fluid units, and mobile-first strategy to adapt layouts. Prepares students to deliver cross-device experiences in all future projects.

  • Lesson 3 • Flexbox Layout

    Introduces the flex container and item model for one-dimensional layouts. Students build navigation bars and card grids used in the capstone project.

  • Lesson 4 • CSS Syntax and Selectors

    Explains rules, declarations, and the full selector spectrum. Establishes specificity and cascade rules that govern every styling decision in this chapter.

  • Lesson 5 • CSS Grid Layout

    Covers grid tracks, areas, and placement for two-dimensional layouts. Extends flexbox skills to handle complex page structures efficiently.

  • Lesson 6 • The Box Model and Spacing

    Covers margin, border, padding, and content area sizing. Mastery here prevents the most common layout bugs encountered in real projects.

Chapter 4See details

JavaScript Fundamentals

  • Lesson 1 • Error Handling and Debugging

    Introduces try/catch, console methods, and browser debugger tools. Builds systematic debugging habits essential for all advanced JavaScript work.

  • Lesson 2 • Control Flow and Loops

    Teaches if/else, switch, for, while, and do-while constructs. Enables students to write decision-making and iterative logic for real-world problems.

  • Lesson 3 • Functions and Scope

    Explains function declarations, expressions, arrow functions, and closure. Scope mastery prevents the variable-access bugs common in DOM scripting.

  • Lesson 4 • Arrays and Objects

    Covers array methods, object literals, and destructuring. Prepares students to manipulate the data structures returned by APIs in Chapter 5.

  • Lesson 5 • Variables, Types, and Operators

    Covers let, const, primitive types, and arithmetic and logical operators. Establishes the data-handling foundation for all subsequent JavaScript topics.

Chapter 5See details

DOM Manipulation and Events

  • Lesson 1 • Modifying DOM Elements

    Teaches textContent, innerHTML, classList, and style manipulation. Students dynamically update page content in response to data and user actions.

  • Lesson 2 • Forms and User Input Handling

    Covers form submission events, input validation, and preventing default behaviour. Connects HTML form knowledge from Chapter 2 to JavaScript-driven UX.

  • Lesson 3 • Querying and Traversing the DOM

    Covers querySelector, getElementById, and parent/child traversal methods. Establishes the selection skills needed before any DOM modification is attempted.

  • Lesson 4 • Event Handling

    Explains addEventListener, event objects, and propagation phases. Enables students to wire up interactive behaviours to any element on the page.

  • Lesson 5 • Building Interactive UI Components

    Applies DOM and event skills to build modals, tabs, and accordions. Synthesises all chapter concepts into reusable, accessible component patterns.

Chapter 6See details

Asynchronous JavaScript and APIs

  • Lesson 1 • Async/Await Syntax

    Rewrites promise chains using async functions and await expressions. Produces cleaner, more maintainable async code used in all subsequent projects.

  • Lesson 2 • Asynchronous Programming Concepts

    Explains the event loop, call stack, and task queue. Provides the mental model required to reason about timing in all async JavaScript code.

  • Lesson 3 • Fetching Data from REST APIs
