The <output> Tag in HTML 5

The <output> tag is used in an HTML form.

<output> Tag Syntax

   ... flow content expected ...
   <form id="form-id" method="GET|POST|etc." action="target-URL">
      ... phrasing content expected ...<output>... phrasing content ...
      ... phrasing content ...</output>...
   ... phrasing content expected ...<output form="form-id">... phrasing content ...
   ... phrasing content ...</output>...
Rules for coding HTML output elements

Make sure you understand the difference between a tag and element and are familiar with the definitions of namespace and other HTML terms.

  1. Code the output element where phrasing content is expected, usually inside a form element.
  2. Begin the output element with a starting <output> tag. The element name uses lower case letters and should be in the HTML namespace, which it will pick up automatically from the xmlns attribute on the <html> tag.
  3. If the field is for a form that can be submitted but is outside that form element, include a form attribute referencing the form the output is to be associated with.
  4. Include any other attributes on the <output> tag as appropriate.
  5. Inside the output element, between the starting <output> tag and the ending </output> tag, code the inner HTML phrasing content.
  6. End the output element with a matching </output> closing tag.
Content Model
Contents of the output element

What's new in HTML 5

The <output> tag is one of the new elements in HTML 5.

Differences between HTML 5 and earlier versions of HTML

The <output> tag did not exist in older versions of HTML.

The 2000-2010 Recommendations from the W3C HTML Working Group defined the HTML namespace for the names of all HTML element types, which now includes the output element name. In older (pre-2000) versions of HTML, element type names were not associated with a namespace.
