position-anchor

The position-anchor CSS property specifies the default anchor element for a positioned element. This default is used by position-area and position-try, and by anchor functions (anchor() and anchor-size()) when no <anchor-name> argument is provided to those functions.

This property is only relevant to “positioned” elements — elements and pseudo-elements that have a position of absolute or fixed set.

To position an element relative to an anchor element, the positioned element requires three features: an association, a position, and a location. The position-anchor and anchor-name properties provide an explicit association.

The anchor element accepts one or more <dashed-ident> anchor names set on it via the anchor-name property. When one of those names is then set as the value of the positioned element’s position-anchor property, the two elements are associated.

Syntax example: position-anchor: normal;
