LDEV 5397 remove href="#nogo" and similar nonexistant same-page link Due to screenreader requirements we can no longer use links having href="#target" when a page does not have this corresponding target. There are a couple of techniques instead of it: 1. links' onclick event should end with "return false;" ("false" can be replaced with anything else but true) It applies to onclick events specified as tag attributes as well as added with Javascript or jQuery 2. turn links into <button type="button"> 3. <a data-bs-toggle="collapse"> having href="#nogo" are OK. presumably as their onclick events return false;
