Know and understand the function of a hyperlink

Website Authoring – The Function of a Hyperlink (ICT 0417)

1. The Three Web‑Development Layers

  • Content layer – HTML defines the structure and meaning of the page.

  • Presentation layer – CSS controls the visual appearance.

  • Behaviour layer – JavaScript can add interactivity, but it is not required for the IGCSE exam. Students only need to recognise that hyperlinks work without any scripting.

2. The HTML Page Skeleton (required tags)

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">                     <!-- character set -->
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="Brief description of the page">
<title>My Web Page</title>
<link rel="stylesheet" href="css/styles.css">   <!-- external CSS file -->
<!--
