2. Meta tags are metadata about data. Metadata quite simply is a set of data that describes and gives information about other data.
3. Meta tags specify page description and keywords in an HTML document. Meta tags are used to provide information about a web page. The meta tags are optional and easy to use.
4. The <meta> tag always goes inside the <head> element. The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.
5. Metadata is always passed as name/value pairs. There are differences between HTML and XHTML meta tag use. In HTML the <meta> tag has no end tag. In XHTML the <meta> tag must be properly closed.
6. There are three main attributes of meta tags: name, content, and http-equiv. The name attribute specifies the type of information. The content attribute includes the meta-information. While, the http-equiv attribute specifies a particular header type.
7. Name- Can be anything. Examples include, keywords, description, author, revised, generator etc. Content- Specifies the property's value. Scheme-Specifies a scheme to use to interpret the property's value (as declared in the content attribute). http-equiv- Can be used to refresh the page or to set a cookie. Values include content-type, expires, refresh and set-cookie.
