what is the use of html meta tag code example
Example 1: html meta tags
<head lang="en">
<meta http-equiv="content-language" content="en">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="keywords" content="website, blog, foo, bar">
<meta name="author" content="John Doe">
<meta name="publisher" content="John Doe">
<meta name="copyright" content="John Doe">
<meta name="description" content="This short description describes my website.">
<meta name="page-topic" content="Media">
<meta name="page-type" content="Blogging">
<meta name="audience" content="Everyone">
<meta name="robots" content="index, follow">
<title>My website title</title>
</head>
Example 2: meta tag
The <meta> tag defines metadata about an HTML document. Metadata is data (information) about data.
<meta> tags always go inside the <head> element, and are typically used to specify character set, page description, keywords, author of the document, and viewport settings.
Metadata will not be displayed on the page, but is machine parsable.
Metadata is used by browsers (how to display content or reload page), search engines (keywords), and other web services.
There is a method to let web designers take control over the viewport (the user's visible area of a web page), through the <meta> tag (See "Setting The Viewport" example below).
