How do I show the missing hours and minutes by 00:00 (midnight)?
Example:
I have a sales site where I want to put a countdown that tells the remaining time to midnight, which when midnight comes, appears 23h 59m 59s.
It's going to be some kind of propaganda, like, "Run! There's only XXh XX m XXs left"
If the person has for example at 20:31, it will show 3h 29m 00s.
And so sussecientemente ....
I saw this example, but I did not have the ability to make it work: link
I just want something simple, just a text "XXh XXm XXs". No CSS.
