CSS Likhnay Ke 3 Tareeke

1. Inline CSS

Direct HTML tag ke andar likhte hain:

<h1 style="color: red;">Hello World</h1>

2. Internal CSS

HTML ke <head> section me <style> tag ke andar likhte hain:

<style>
  h1 {
    color: green;
  }
</style>

3. External CSS (Best Practice)

Alag .css file me likhkar HTML se link karte hain:

<link rel="stylesheet" href="style.css">

Hamesha external CSS use karna chahiye kyunki ye code ko clean aur manageable banata hai.

Simple CSS Syntax

selector {
  property: value;
}

Example:

h1 {
  color: purple;
  font-size: 30px;
}

Sabhi <h1> headings purple dikhenge aur 30px font size me aayenge.

Real-World CSS Example

index.html

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <h1>Welcome to My Blog</h1>
  <p>This is a simple paragraph.</p>
</body>
</html>

style.css

body {
  background-color: #f5f5f5;
}

h1 {
  color: darkblue;
  text-align: center;
}

p {
  font-size: 18px;
  color: #444;
}

Code OutPut

Is example me webpage ka background halka grey (#f5f5f5) hai. Heading dark blue color me center aligned hai, aur paragraph ka text grey (#444) color aur 18px font size me hai. Ye ek simple aur clean CSS styling ka example hai jo beginners ke liye perfect hai.
