What is Frontend Development?
Frontend development involves building the part of a website or application that users interact with directly. It is the "client-side" of software.
Think of a website like a house:
- HTML is the structure (walls, doors, layout).
- CSS is the decoration (paint, carpet, style).
- JavaScript is the functionality (electricity, plumbing, opening the garage door).
Phase 1: Foundations
This is where I starts. You must master the "Big Three" (HTML, CSS, JavaScript) before touching any modern frameworks.
1. HTML5 (The Structure)
HTML (HyperText Markup Language) tells the browser what content is on the page.

2. CSS3 (The Styling)
CSS (Cascading Style Sheets) controls how your HTML looks.
Documentation:
3. JavaScript (The Interactivity)
JavaScript (JS) makes the page do things. It handles logic, updates content, and communicates with servers.
Documentation:
4. TypeScript
TypeScript is JavaScript with "types." It helps catch errors before you run the code.
Documentation:
5. HTTP & Web Fundamentals
You need to know how the web works. HTTP is the protocol used to fetch documents over the internet.
Documentation:
6. Version Control with Git
Git saves versions of your code. It acts like a "save point" in a game.
