In other words meta tag is meta data which is a data of data and web browsers use meta data to display content, reload page, search query keywords (search engines), and so on (w3schools, 2023). Charset, content, http-eqv, and name are the four common attributes of the meta tag (w3schools, 2023). Charset attribute have "character_set" value which sets the encoding format of the character in the HTML document (w3schools, 2023). Similarly, name attribute stores six different values (application-name, author, description, generator, keywords, and viewport) which defines the name of metatag (w3schools, 2023). Content attribute stores text value which specifies the data related with "http-eqv" or "name" (w3schools, 2023). Finally, the http-eqv tag have four values (contebt-security-policy, content-type, default-style, and refresh) which provides HTTP header for information or, value of content attribute (w3schools, 2023).
