The <meta> HTML element is used to provide metadata about an HTML document. Metadata is information about the data on the webpage, and it is not displayed on the page itself. Instead, it is used by browsers, search engines, and other web services to understand and process the content of the page. The <meta> element is typically placed within the <head> section of an HTML document.
Usage and Characteristics
The <meta> element is a void element, meaning it does not have a closing tag. It can be used to specify various types of metadata, such as character set, page description, keywords, author, and viewport settings. Here is an example of how the <meta> tag can be used:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="A sample webpage demonstrating the use of meta tags.">
<meta name="keywords" content="HTML, CSS, JavaScript, meta tags">
<meta name="author" content="John Doe">
<title>Sample Page</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a sample webpage.</p>
</body>
