<anchor>
Allows an element (like a tooltip or menu) to be docked to another element on the page, ensuring it stays positioned relative to that target even if the page scrolls or layout changes.
Usage example
.tooltip {
/* Docks the top of the tooltip to the bottom of the anchor */
top: anchor(bottom);
position: absolute;
