HTML: The Structure
HTML (HyperText Markup Language) forms the basic structure of a webpage. You use tags to define text, links, images, and layout.
<!DOCTYPE html>
<html>
  <head>
    <title>My First Page</title>
  </head>
  <body>
    <h1>Hello World</h1>
    <p>Welcome to coding!</p>
  </body>
</html>
      Each tag like <h1> or <p> defines a different kind of content on your site.
CSS: The Design
CSS (Cascading Style Sheets) controls how everything looks: colors, spacing, fonts, and layout.
body {
  background-color: #f8f9fb;
  font-family: Arial, sans-serif;
  color: #333;
}
h1 {
  color: #0077cc;
}
      Save CSS in a separate style.css file and link it in your HTML with:
<link rel="stylesheet" href="style.css">
    JavaScript: The Logic
JavaScript makes your webpage interactive. It can respond to user actions like clicks and keyboard input.
<script>
  function showMessage() {
    alert("Welcome to your first script!");
  }
</script>
<button onclick="showMessage()">Click Me</button>
      When you click the button, the script runs and shows a message!
