The HTML <head> Element

The <head> element is a container for all the head elements. Elements inside <head> can include scripts, instruct the browser where to find style sheets, provide meta information, and more.
The following tags can be added to the head section: <title>, <base>, <link>, <meta>, <script>, and <style>.

The HTML <title> Element

The <title> tag defines the title of the document.
The title element is required in all HTML/XHTML documents.
The title element:
  • 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
A simplified HTML document:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
</head>
<body>
The content of the document......
</body>
</html>


The HTML <base> Element

The <base> tag specifies a default address or a default target for all links on a page:
<head>
<base href="http://www.w3schools.com/images/" />
<base target="_blank" />
</head>


The HTML <link> Element

The <link> tag defines the relationship between a document and an external resource.
The <link> tag is most used to link to style sheets:
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css" />
</head>


The HTML <style> Element

The <style> tag is used to define style information for an HTML document.
Inside the style element you specify how HTML elements should render in a browser:
<head>
<style type="text/css">
body {background-color:yellow}
p {color:blue}
</style>
</head>


The HTML <meta> Element

Metadata is information about data.
The <meta> tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine readable.
Meta elements are typically used to specify page description, keywords, author of the document, last modified, and other metadata.
The <meta> tag always goes inside the head element.
The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.

Keywords for Search Engines

Some search engines will use the name and content attributes of the meta element to index your pages.
The following meta element defines a description of a page:
<meta name="description" content="Free Web tutorials on HTML, CSS, XML" />
The following meta element defines keywords for a page:
<meta name="keywords" content="HTML, CSS, XML" />
The intention of the name and content attributes is to describe the content of a page.

The HTML <script> Element

The <script> tag is used to define a client-side script, such as a JavaScript.
The script element will be explained in a later chapter.
