HTMLTemplateElement

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since November 2015.

* Some parts of this feature may have varying levels of support.

The HTMLTemplateElement interface enables access to the contents of an HTML <template> element.

Note: An HTML parser can create either an HTMLTemplateElement or a ShadowRoot when it parses a <template> element, depending on the <template> attributes. If an HTMLTemplateElement is created the "shadow" attributes are reflected from the template. However these are not useful, because an HTMLTemplateElement is not a shadow root and cannot subsequently be changed to a shadow root.
