HTML output element

The <output> HTML element is a container element into which a site or app can inject the results of a calculation or the outcome of a user action.

Many browsers implement this element as an aria-live region. Assistive technology will thereby announce the results of UI interactions posted inside it without requiring that focus is switched away from the controls that produce those results.

Live-region updates are generally announced as plain text, so links, buttons, and other semantics nested inside <output> may not be conveyed in the announcement.

Attributes: for A space-separated list of other elements’ ids, indicating that those elements contributed input values to (or otherwise affected) the calculation. form The <form> element to associate the output with (its form owner). The value of this attribute must be the id of a <form> in the same document. (If this attribute is not set, the <output> is associated with its ancestor <form> element, if any.)
