META

On page 180 of Learning, the meta element is defined as "an empty element that provides information about the document, such as its creation date, author, copyright information, and the character coding and type file." Upon further research I found out the meta tags are used in the head of the page and are invisible. They also help search engines find your site, such as keywords that will allow search engines to recognize what your site is about.
