Day1/180-Introduction to Frontend Development and How the Web Works

Welcome to Day 1 of the 180 Days of Frontend Development Challenge. Whether you're a complete beginner or someone looking to refine your skills, this journey will take you through the fundamentals of frontend development, one step at a time. By the end of these 180 days, you’ll have a solid understanding of how to build interactive, responsive, and visually appealing websites.

What is Frontend Development?

Frontend development, also known as client-side development, involves creating the part of a website that users interact with directly. This includes everything you see on a webpage—buttons, forms, layouts, animations, and more. Frontend developers use three core technologies:

1. HTML (HyperText Markup Language) – The backbone of any webpage, defining its structure and content.
2. CSS (Cascading Style Sheets) – Controls the visual presentation, including colors, fonts, and layouts.
3. JavaScript – Adds interactivity, allowing web pages to respond to user actions dynamically.

Beyond these basics, modern frontend development also involves frameworks like React, Vue, or Angular, as well as tools like Webpack and npm to streamline the development process.

How the Web Works

Before diving into coding, it’s essential to understand how the web functions at a high level.

1. The Client-Server Model

   • When you type a URL into your browser (the client), it sends a request to a server (a remote computer hosting the website).
   • The server processes the request and sends back the necessary files (HTML, CSS, JavaScript, images, etc.).
   • Your browser then renders these files into the webpage you see.

2. DNS (Domain Name System)

   • The internet uses IP addresses (e.g., 192.168.1.1) to identify servers, but humans prefer domain names (e.g., google.com).
   • DNS translates domain names into IP addresses so browsers can locate the correct server.

3. HTTP/HTTPS Protocols

   • HTTP (HyperText Transfer Protocol) defines how data is transmitted between the client and server.
   • HTTPS is the secure version, encrypting data to protect sensitive information.

4. Rendering the Page

   • Once the browser receives the files, it parses the HTML to create the DOM (Document Object Model), a tree-like structure of the page.
   • CSS is applied to style the elements.
   • JavaScript executes to add functionality, manipulate the DOM, or fetch additional data.
