Chapter Goals

Modern front-end development is filled with various libraries and frameworks. While they offer many helpful features, they all eventually boil down to the same core: HTML, CSS, and JavaScript, which are parsed and run by the Browser.

The goal of this chapter is to help you build a stable mental model of how the web works by mastering the core languages and understanding the browser environment before introducing complex frameworks.

Learning Resources

🌐 The Browser: How the Web Works

Before writing code, understand how the browser receives, parses, and renders a web page.

  Why: An excellent series from the Chrome team. It explains the "inner workings" of a browser, from the network request to the final pixels on the screen.
• MDN: How the Web Works ⭐⭐⭐⭐
  Why: A simple, high-level overview of servers, clients, and HTTP. Essential for understanding the "big picture."

🏗️ HTML: Structure & Semantics

Learn how to build a meaningful and accessible skeleton for your content.

• web.dev: Learn HTML ⭐⭐⭐⭐⭐
  Why: Modern, bite-sized lessons. It focuses on writing "Semantic HTML" which is crucial for SEO and accessibility.
• MDN: HTML First Steps ⭐⭐⭐⭐
  Why: A structured guide that explains document metadata, headings, and lists in a very clear way.

🎨 CSS: Styling & Modern Layout

Master the art of positioning elements using native Flexbox and Grid.

• web.dev: Learn CSS ⭐⭐⭐⭐⭐
  Why: Highly visual explanations of the Box Model and Selectors.
