// fragment anchor allows a page to link to a specific part of a page by using
// the URL fragment. The fragment is the part after the '#' character. E.g.
// navigating to www.example.com/index.html#section3 will find the element with
// id "section3" and focus and scroll it into view.
//
// This class provides an interface that different types of fragment anchors
// can implement, allowing fragments to specify different kinds of anchors.
// Callers should use the TryCreate static method to create and return the
// appropriate type of base class.
