Web Development for Beginners

Web development lets you create for the internet. This post covers essential tools, languages, and steps to start building websites.

What is Web Development?

Creating websites and applications by combining front-end (visuals) and back-end (logic).

Key Components:

  • HTML: Structure
  • CSS: Style
  • JavaScript: Interactivity

Essential Tools

  1. Code Editor: VS Code
  2. Browser: Chrome or Firefox
  3. Version Control: Git & GitHub
  4. Terminal (optional)

Step 1: Learning HTML

HTML creates structure with elements like headings and paragraphs.

<!DOCTYPE html>
<html>
  <head>
    <title>My Web Page</title>
  </head>
  <body>
    <h1>Welcome!</h1>
  </body>
</html>

Step 2: Styling with CSS

CSS adds colors, fonts, and layout to your HTML.

body {
  font-family: Arial;
  background: #f4f4f4;
}
h1 {
  color: #333;
}

Step 3: Adding JavaScript

JavaScript makes pages interactive.

document.querySelector("h1").textContent = "Welcome!";

Step 4: Understanding Back-End

The back-end handles server, database, and logic.

const express = require("express");
const app = express();
 
app.get("/", (req, res) => res.send("Hello!"));
app.listen(3000);
