Answer 3

The <meta> tag in HTML provides information about HTML Document or in simple words, it provides important information about a document. These tags are basically used to add name/value pairs to describe properties of HTML documents, such as expiry date, author name, list of keywords, document author, etc. This tag is an empty element because it only has an opening tag and no closing tag, but it carries information within its attributes. A web document can include one or more meta tags depending on information, but in general, it doesn’t affect the physical appearance of the document.
