Animation when downloading a file to a computer?

Question

JavaScript

Not to be confused with download. On some foreign sites I saw such a feature. When you click on the link and the download of the file starts on the page, for example, some arrow with a notification that the download has begun blinks. Has anyone come across such solutions?

Answer 1

When you click on the file download, it is required that the animation appear on the arrow, did I understand correctly?
We enter into the script, and replace a.download with our own arrow.

$("a.download").click(function () {
        $("a.download").addClass("animated ИмяАнимации");
