How to add a class to the next flight?

Question

css

There is such a page 26060.ru/r
I can’t figure out how to add a class to the next flight in order to visually highlight it.
Can you suggest a solution.

upd. You need to compare with the time according to Moscow time and add a class to the next of the future flights.

Answer 1

codepen
I didn't test it in detail, you can change the time yourself and see how it switches.

Answer 2

As for me, it's better to do this on the server side, take the current date and compare it with the flight time, and immediately add a class, for example .next_flight and that's it
