Is there a CSS “:drop-hover” pseudo-class?

Question

Saying I have an input type=\"file\" field. One can drop a file on this input(like in Firefox) instead of clicking \"browse\" and selecting the file.

Answer 1

UPDATE: Thanks to @Renato's comment, according to https://github.com/w3c/csswg-drafts/issues/2257, the drop pseudo-class has been dropped now.

There is :drop and :drop() pseudo-class, which is currently in Working Draft status.

According to http://css4.rocks/selectors-level-4/drag-and-drop-pseudo-class.php, the browser support is not good.

For "file being dropped is not accepted" case, :drop(invalid active) is expected to work, in future.
