HTML <template> Tag

The HTML <template> tag allows you to declare fragments HTML fragments that can be cloned and inserted into the document by script.

The <template> tag allows you to declare HTML fragments that are not used when the document loads, but can be used later (upon a given user action for example).

The contents of the <template> element are not part of the document until you use it. Therefore, until you use it, none of its contents are downloaded, and you can't reference it via the DOM.

When the contents of the <template> element are used, they are cloned and inserted into the DOM. Therefore, you can use it multiple times, and you can even add to its contents.


The <template> tag is written as <template></template> with the template content between the start and end tags.

The global id attribute can be used so that scripts can refer to the element.

Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.
