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>, <style>,
<meta>, <link>,
<script>, <noscript>, and <base>.
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 the base URL/target for all relative URLs in a
page:
<head>
<base href="http://www.Google.com/images/" 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 data (information) about data.
The <meta> tag provides metadata about the HTML document. Metadata will not
be displayed on the page, but will be machine parsable.
Meta elements are typically used to specify page description, keywords,
author of the document, last modified, and other metadata.
The metadata can be used by browsers (how to display content or reload page),
search engines (keywords), or other web services.
<meta> tags always go inside the <head>
element.
<meta> Tags - Examples of Use
Define keywords for search engines:
<meta name="keywords" content="HTML, CSS, XML, XHTML, JavaScript">
Define a description of your web page:
<meta name="description" content="Free Web tutorials on HTML and CSS">
Define the author of a page:
<meta name="author" content="Hege Refsnes">
Refresh document every 30 seconds:
<meta http-equiv="refresh" content="30">
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.
