+The **URL fragment text directives** API allows web apps to interact with _text fragments_ in the URL. [Text fragments](/en-US/docs/Web/URI/Fragment/Text_fragments) allow linking directly to a specific portion of text in a web document, without requiring the author to annotate it with an ID, using a particular syntax in the URL fragment.
+
+## Interfaces
+
+- {{domxref("FragmentDirective")}}
+  - : A (currently) empty object.
+    The existence of an object of this type in {{domxref("document.fragmentDirective")}} is used for feature detection.
+
+## Extensions to other interfaces
+
+- {{domxref("Document.fragmentDirective")}}
+  - : A property that returns a `FragmentDirective` object for the current document. Currently only used for feature detection.
+
+## CSS selectors
+
+- {{cssxref("::target-text")}}
+  - : Represents the text that has been scrolled to. It allows authors to choose how to highlight that section of text.
