Overview

Welcome to Web Development Fundamentals, the second course in the JavaScript Starter Kit Professional Certificate program. This course will introduce you to the essential technologies for modern web development, teaching you how to create professional, responsive websites using HTML, CSS, and DOM manipulation with JavaScript. By the end of this course, you will be able to: - Create professional web page structures using semantic HTML elements and accessibility best practices - Implement responsive web designs using CSS properties and layout techniques that work across all device sizes - Develop dynamic web content using DOM manipulation and event handling to create interactive user experiences - Design and implement secure data management systems with proper form validation and XSS prevention - Build a complete To-Do List web application that demonstrates mastery of HTML, CSS, and JavaScript integration For the final project in this course, you will progressively develop a fully functional To-Do List web application that combines all web development fundamentals into a portfolio-ready project. You'll create semantic HTML structures, implement responsive CSS designs, build interactive features using DOM manipulation, handle user events and form submissions, and manage data persistence using browser storage. Throughout the development process, you'll learn to follow professional web standards, implement accessibility best practices, and create secure, user-friendly web applications that demonstrate real-world development skills. To succeed in this course, you should have programming experience with JavaScript variables, functions, control flow, and basic data structures. Familiarity with basic computer concepts and comfort using a web browser are also required. The course uses an online development environment, so you can start building web applications immediately.

Syllabus

HTML Foundations

Master the building blocks of web development by learning to create well-structured, accessible web pages using HTML. You'll start with basic HTML document structure and progress to implementing semantic elements that improve both SEO and accessibility. By the end of this module, you'll build professional HTML forms with proper validation and create the complete HTML foundation for your To-Do List application, following industry standards for document organization and user experience.

CSS Essentials

Transform your HTML structures into visually appealing, professional websites using CSS styling and layout techniques. You'll learn to apply colors, typography, and spacing using the CSS box model, then advance to creating responsive designs that work seamlessly across all device sizes. This module culminates in implementing a complete visual design system for your To-Do List application, ensuring it looks professional on desktop, tablet, and mobile devices.

Dynamic Web Content with the DOM

Bring your web pages to life by learning to manipulate HTML elements dynamically using JavaScript and the Document Object Model (DOM). You'll master selecting, modifying, and creating elements programmatically to update content without page refreshes. By the end of this module, you'll implement dynamic task creation and management features in your To-Do List application, creating the interactive foundation that modern web applications require.

Events and Interaction

Create engaging user experiences by implementing event-driven programming that responds to user actions like clicks, form submissions, and keyboard input. You'll learn to handle various event types efficiently and implement event delegation patterns for optimal performance. This module enables you to build a fully interactive To-Do List application where users can add, edit, complete, and manage tasks through intuitive interface interactions.

Data and Storage

Complete your web application by implementing secure data management and persistence using browser storage technologies. You'll learn to validate user input, prevent security vulnerabilities like XSS attacks, and store application data locally so users don't lose their work. By the end of this module, your To-Do List application will be a fully functional, secure web application that maintains user data across browser sessions and follows professional security best practices.
