<aside> Redirect 1

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.

Usage notes:

  • Do not use the <aside> element to tag parenthesized text, as this kind of text is considered part of the main flow.


This element only includes the global attributes.


  <p>Some content related to an &lt;article&gt;</p>
