Understanding the foundations of web development is the first step toward building websites and web apps.
1๏ธโฃ What is Web Development?
Web development is the process of creating websites and web applications. It includes everything from a basic HTML page to full-stack apps.
Types of Web Dev:
- Frontend: What users see (HTML, CSS, JavaScript)
- Backend: Server-side logic, databases (Node.js, Python, etc.)
- Full Stack: Both frontend + backend
2๏ธโฃ How the Web Works
When you visit a website:
- The browser (client) sends a request via HTTP
- The server processes it and sends back a response (HTML, data)
- Your browser renders it on the screen
Example: Typing
www.example.com sends a request โ DNS resolves IP โ Server sends back the HTML โ Browser displays it 3๏ธโฃ HTML (HyperText Markup Language)
Defines the structure of web pages.
<h1>Welcome</h1>
<p>This is my first website.</p>
*4๏ธโฃ CSS (Cascading Style Sheets)*
Adds *style* to HTML: colors, layout, fonts.
h1 {
color: blue;
text-align: center;
}*5๏ธโฃ JavaScript (JS)*
Makes the website *interactive* (buttons, forms, animations).
<button onclick="alert('Hello!')">Click Me</button>*6๏ธโฃ Responsive Design*
Using *media queries* to make websites mobile-friendly.
@media (max-width: 600px) {
body {
font-size: 14px;
}
}*7๏ธโฃ DOM (Document Object Model)*
JS can interact with page content using the DOM.
document.getElementById("demo").innerText = "Changed!";*8๏ธโฃ Git & GitHub*
Version control to track changes and collaborate.
git init
git add .
git commit -m "First commit"
git push
*9๏ธโฃ API (Application Programming Interface)*
APIs let you pull or send data between your app and a server.
fetch('https://api.weatherapi.com')
.then(res => res.json())
.then(data => console.log(data));๐ Hosting Your Website
You can deploy websites using platforms like Vercel, Netlify, or GitHub Pages.
๐ก Once you know these basics, you can move on to frameworks like React, backend tools like Node.js, and databases like MongoDB.
