No matter how much you study React, Next.js, or Vue, if the code feels abstract and the structure isn't clearly understood, the root cause might be a lack of understanding of DOM. DOM is the foundation of all frontend frameworks and the entity that connects the structure and behavior of web pages. This lecture goes beyond simple selectors or manipulation methods, teaching step-by-step from the very beginning how HTML transforms into DOM objects and how to select, traverse, and manipulate this structure. It is the Part 1 introductory lecture of 'Complete DOM Mastery'. HTML tags are just structure, and JavaScript is just behavior, but DOM is the core that connects the two. If you clearly understand this connection, you'll be able to precisely grasp the true structure and flow within any framework you use.

In this course, I will guide you step by step through the process of building a complete, modern, and professional portfolio website using Next.js 14, React.js, Tailwind CSS, and Nodemailer. Based on my experience helping students understand complex front-end concepts, I focus on clear explanations, real-world examples, and practical implementation. Instead of just explaining theory, we build everything together—from project setup to final deployment—so you fully understand why and how things work. You will learn the core concepts of Next.js 14, including the App Router, file colocation, private and dynamic routes, navigation, layouts, metadata, and loading states. Once the fundamentals are clear, we will build a full portfolio website with dynamic content, smooth scrolling animations, downloadable PDF files, and call-to-action buttons driven by scroll state. By the end of the course, you will deploy your website on Vercel, publish the source code on GitHub, and confidently understand the difference between React routing and Next.js routing, while knowing how to build real-world, production-ready applications. No prior experience with Next.js is required.
