Html Head Element: A Guide to Creating Metadata and Enhancing SEO
You will discover the significance of head parts in this session.
The HTML head Element
The main function of the <head> element is to serve as a container for various head elements that provide additional
information about the HTML document, known as metadata, or references to external resources required for proper display and functionality in web browsers.
These head elements collectively describe important aspects of the document, such as the title, and provide metadata like the character encoding. They also guide the browser in locating the necessary style sheets or scripts, allowing for the dynamic and interactive enhancement of the HTML document.
Common HTML elements that can be included within the <head> element include <title>,
<base>, <link>, <style>, <meta>,
<script>, and the <noscript> elements.
The HTML title Element
The <title> element is responsible for defining the title of an HTML document.
In HTML/XHTML documents, the presence of a <title> element is necessary for a document to be considered valid.
Only one <title> element is allowed per document, and it must be placed within
the <head> element. The content of the <title> element should consist of
plain text and entities, and it should not contain any other markup tags.
The title of the document serves various purposes. For instance:
- Firstly, it is used to display a title in the browser's title bar and taskbar, providing a recognizable name for the webpage.
- Additionally, the title is used when the page is added to favorites or bookmarked, allowing users to easily identify the bookmarked page.
- Lastly, the title is often displayed in search engine results, helping users understand the content and relevance of the page before visiting it.
<head>
<title>A simple HTML document</title>
</head>
<body>
<p>Happy Moring..</p>
</body>
Tip: An effective title for an HTML document should be concise and directly related to the content it represents. This is important because search engine web crawlers place significant emphasis on the words used within the title. Ideally, the title should be kept under 65 characters in length to ensure optimal visibility and readability in search engine results.
The HTML base Element
The HTML <base> element serves the purpose of establishing a base URL that serves as the starting point for
all relative links within the document. By setting the base URL once at the top of the page, subsequent relative links will utilize this URL
as their reference point. This can be particularly useful in simplifying and managing relative links throughout the document.
<head>
<title>Defining a base URL</title>
<base href="https://www.simmanchith.com"/>
</head>
<body>
<p><a href="tutorial/html/html-head.aspx">HTML Head</a>.</p>
</body>
For instance, if the base URL is defined as https://www.simmanchith.com/, any relative links that follow will be resolved based on this base URL. In the provided example, the relative link tutorial/html/html-head.aspx will be combined with the base URL, resulting in the resolved URL of https://www.simmanchith.com/tutorial/html/html-head.aspx, regardless of the current page's URL.
Warning: It is important to note that the <base> element must be positioned before any elements
that reference external resources. Furthermore, it is crucial to remember that HTML only allows for a single <base> element within each document.
The HTML link Element
The relationship between the current document and external documents or resources is indicated using the <link> tag.
One common use of the link element is to connect to external style sheets.
<head>
<title>Linking Style Sheets</title>
<link rel="stylesheet" href="sample.css">
</head>
Note: It's worth noting that the <head> section of an HTML page can include multiple
<link> elements. Despite not having any content, the <link> tag does possess attributes.
The HTML style Element
To define the inline style data for an HTML page, the <style> tag is used. The appearance of HTML tags in a viewer
is dictated by the style rules specified within the <style> section.
<head>
<title>Embedding Style Sheets</title>
<style>
body { background-color: purple; }
h1 { color: skyblue; }
p { color: yellow; }
</style>
</head>
Note: It is important to use an embedded style sheet when a single document requires a unique style. If the same style sheet is used across multiple pages, it is advisable to use an external style sheet.
The HTML meta Element
The <meta> tag is used to provide metadata for an HTML document. Metadata refers to a
set of data that provides information and descriptions about other data. Here is an example:
<head>
<title>Defining Metadata</title>
<meta charset="utf-8">
<meta name="author" content="text">
</head>
The HTML script Element
Client-side scripts, including JavaScript, are declared using the <script> tag in HTML documents. The following example
demonstrates how a new message will be displayed in web browsers:
<head>
<title>Adding JavaScript</title>
<script>
document.write("<h1>Happy morning</h1>")
</script>
</head>
