What are the common HTML header tags?

HTML (Hypertext Markup Language) is the standard markup language used to create and structure web pages. The HTML header tags are a set of elements that provide important information about the webpage, such as the title, metadata, and other configuration details. These header tags are typically placed within the <head> section of an HTML document.

Here are the common HTML header tags:

<title>: The <title> tag defines the title of the webpage, which is displayed in the browser's title bar or tab. This tag is crucial for search engine optimization (SEO) and helps users identify the content of the page.
<meta>: The <meta> tag is used to provide metadata about the webpage, such as the character encoding, description, keywords, and other information that is not directly visible on the page. This metadata is used by search engines and other applications to understand the content and context of the webpage.
<link>: The <link> tag is used to establish a relationship between the current document and an external resource, such as a stylesheet (CSS) or a favicon.
<style>: The <style> tag is used to define the styling information for the webpage, typically in the form of Cascading Style Sheets (CSS).
<script>: The <script> tag is used to include or reference client-side scripts, such as JavaScript, that add interactivity and dynamic functionality to the webpage.
<base>: The <base> tag specifies the base URL for all relative URLs in the document, which can be useful when the webpage is hosted on a different server or directory.
<noscript>: The <noscript> tag is used to provide alternative content for users whose browsers do not support or have disabled JavaScript.

Here's a simple example of an HTML document with some of the common header tags:

<!DOCTYPE html>
<html>
<head>
  <title>My Webpage</title>
  <meta charset="UTF-8">
  <meta name="description" content="This is a sample webpage.">
  <meta name="keywords" content="HTML, CSS, JavaScript">
  <link rel="stylesheet" href="style.css">
  <script src="script.js"></script>
</head>
<body>
  <!-- Main content of the webpage -->
</body>
</html>

To further illustrate the relationships and hierarchy of these HTML header tags, here's a Mermaid diagram:

In summary, the HTML header tags provide essential information about the webpage, including the title, metadata, and external resources. Understanding and properly using these tags can help improve the structure, visibility, and functionality of your web pages.
