Suggested change

In the context of {{glossary("WebAPI","Web APIs")}}, an interface is a type that describes the {{glossary("method","methods")}}, {{glossary("property","properties")}}, and {{glossary("event","events")}} that a web API object exposes. These interfaces are defined in Web IDL (Interface Definition Language) and are implemented by {{glossary("browser","browsers")}}.

In the context of [Web APIs](/en-US/docs/Web/API), an interface is a type that describes the {{glossary("method","methods")}}, {{glossary("property","properties")}}, and {{glossary("event","events")}} that a Web API object exposes. These interfaces are defined in [Web IDL](/en-US/docs/MDN/Writing_guidelines/Howto/Write_an_api_reference/Information_contained_in_a_WebIDL_file) (Interface Definition Language) and are implemented by {{glossary("browser","browsers")}}.
