The HTML <aside> Element represents a section of a page that consists of content that is tangentially related to the content around it, which could be considered separate from that content. Such sections are often represented as sidebars or as inserts. They often contain side explanations, like a glossary definition; more loosely related stuff, like advertisements; the biography of the author; or in web-applications, profile information or related blog links.
