itemscope

itemscope is a boolean global attribute that defines the scope of associated metadata. Specifying the itemscope attribute for an element creates a new item, which results in a number of name-value pairs that are associated with the element.

A related attribute, itemtype, is used to specify the valid URL of a vocabulary (such as schema.org ) that describes the item and its properties context. In each of the following examples, the vocabulary is from schema.org .

Every HTML element may have an itemscope attribute specified. An itemscope element that does not have an associated itemtype must have an associated itemref.

Note: Find more about itemtype attributes at https://schema.org/Thing

itemscope id attributes

When you specify the itemscope attribute for an element, a new item is created. The item consists of a group of name-value pairs. For elements with an itemscope attribute and an itemtype attribute, you may also specify an id attribute. You can use the id attribute to set a global identifier for the new item. A global identifier allows the item to relate to other items found on pages across the Web.

Examples
