HTML head Tag: A Comprehensive Guide

What is the HTML head Tag?

The <head> tag in HTML contains metadata and links that are not directly displayed on the webpage but are essential for functionality, performance, and SEO. It is placed inside the <html> tag and precedes the <body> tag.

Purpose of the Tag

The <head> section:

  1. Provides metadata (e.g., page title, description).
  2. Links to stylesheets, scripts, and other resources.
  3. Defines the character set and viewport for responsive design.

Basic Syntax of the head Tag

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My HTML Page</title>
</head>
<body>
    <h1>Welcome to My Page</h1>
</body>
</html>

Optimize for SEO: Use relevant meta tags like description and keywords.

Load External Resources Efficiently: Use defer or async attributes for scripts to avoid blocking rendering.

Set Viewport for Mobile Devices: Always include the viewport meta tag for responsive design.

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Use a Favicon: Add a recognizable favicon for branding.

Keep <head> Clean: Avoid inline styles or scripts; prefer external files.
