How to use CSS anchor positioning

thumbnail
  • CSS anchor positioning allows for flexible element tethering by positioning an anchor target element in relation to an anchor element.
  • Anchor positioning provides more flexibility than absolute positioning, as the anchor element can be located anywhere in the DOM.
  • Currently, browser support for anchor positioning is limited, but polyfills can be used to overcome this limitation.
  • The Anchor Positioning API allows for positioning and sizing of anchor target elements in relation to anchor elements.
  • Anchor-based positioning can be achieved by using an implicit or explicit anchor element.
  • The anchor target element can be tethered to the anchor element using the anchor-position attribute and the inset-anchor() function.
  • The API provides properties and functions for declaring and referencing anchor elements, calculating element dimensions, and providing guidance to the browser.
  • The combination of the anchor-position attribute and the inset-anchor() function allows for precise positioning and sizing of elements in relation to their anchor elements.
