Introduction to the Head Element
The HTML <head> element is a container for metadata (data about data) and is placed between the <html> tag and the <body> tag. Metadata is not displayed but is important for the browser and search engines.
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Metadata goes here -->
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Page Title</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<!-- Content goes here -->
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>The Title Element
The <title> element defines the title of the document and is required in all HTML documents. It:
- Defines a title in the browser toolbar
- Provides a title for the page when it is added to favorites
- Displays a title for the page in search engine results

The <meta> element is used to specify character set, page description, keywords, author, and viewport settings. Metadata is used by browsers, search engines, and other web services.
Charset Attribute
Defines the character encoding for the HTML document:
<meta charset="UTF-8">Viewport Settings
Controls the page's dimensions and scaling for responsive design:
<meta name="viewport" content="width=device-width, initial-scale=1.0">Description
Defines a description of your web page for search engines:
<meta name="description" content="Free HTML tutorials">Keywords
Defines keywords for search engines (less important today):
<meta name="keywords" content="HTML, CSS, JavaScript">Author
Defines the author of a page:
<meta name="author" content="John Doe">Refresh
Refreshes the document every 30 seconds:
<meta http-equiv="refresh" content="30">The Link Element
The <link> element defines the relationship between the current document and an external resource. It is most often used to link to external style sheets.
<!-- Link to an external style sheet -->
<link rel="stylesheet" href="styles.css">
<!-- Link to an icon for the website (favicon) -->
<link rel="icon" href="favicon.ico">
<!-- Link to preload important resources -->
<link rel="preload" href="script.js" as="script">
<!-- Link to a CSS file for printing -->
<link rel="stylesheet" href="print.css" media="print">Required. Specifies the relationship between documents
Specifies the location of the linked document
Specifies the media type of the linked document
The Style Element
The <style> element is used to define style information (CSS) for a single HTML document.
<!DOCTYPE html>
<html>
<head>
<style>
body {background-color: powderblue;}
h1 {color: blue;}
p {color: red;}
</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>The Script Element
The <script> element is used to define client-side JavaScript. It can either contain scripting statements or point to an external script file.
<!-- Internal JavaScript -->
<script>
function myFunction() {
document.getElementById("demo").innerHTML = "Hello JavaScript!";
}
</script>
<!-- External JavaScript -->
<script src="myscript.js"></script>
<!-- JavaScript with async loading -->
<script src="script.js" async></script>
<!-- JavaScript with defer loading -->
<script src="script.js" defer></script>Specifies the URL of an external script file
Specifies that the script is executed asynchronously
Specifies that the script is executed when the page has finished parsing
The Base Element
The <base> element specifies the base URL and/or target for all relative URLs in a page. There can be only one <base> element in a document, and it must be inside the <head> element.
<!DOCTYPE html>
<html>
<head>
<base href="https://www.example.com/" target="_blank">
</head>
<body>
<img src="images/stickman.gif" width="24" height="39" alt="Stickman">
<a href="tags/tag_base.asp">HTML base Tag</a>
</body>
</html>Specifies the base URL for all relative URLs in the page
Specifies the default target for all hyperlinks and forms in the page
