meta tag in HTML

The <meta> tag in HTML is used to provide metadata about a web page, which is information that describes the page but is not directly visible to users. Metadata can include details like the character set, author of the document, page description, keywords for SEO, and instructions for browsers.

Common Uses of the <meta> Tag:

1. Character Encoding
   Defines the character set to be used.
   Example:

   <meta charset="UTF-8">

2. Viewport Settings
   Helps with responsive design, controlling the layout on mobile devices.
   Example:

   <meta name="viewport" content="width=device-width, initial-scale=1.0">

3. Page Description
   Provides a brief description of the page, often used by search engines.
   Example:

   <meta name="description" content="Learn about the HTML meta tag and its uses">

4. Keywords
   Contains keywords relevant to the page, although modern search engines don’t heavily rely on this for ranking.
   Example:

   <meta name="keywords" content="HTML, meta tag, web development">

5. Author Information
   Specifies the author of the web page.
   Example:

   <meta name="author" content="John Doe">

6. Refresh or Redirect
   Can be used to refresh or redirect the page after a specific time interval.
   Example:

   <meta http-equiv="refresh" content="5; url=https://example.com">
