There is nothing specific it needs to be as long as it is different for each countdown. Also, it is the entire string that is the class. The class for the volume 5 countdown, as I have recommended, is "post-countdown-5"; "5" because it is volume 5. Similarly, my recommended class for the colume 3 countdown is "post-countdown-3".

Multiple classes are separated by a space character. For example, "hello-there" is a single class while "hello there" is two classes ("hello" and "there").

After taking a look at the script itself, it seems that you don't actually have to use a class for the toggle feature; that is just how they do it in the example. If you do "next" instead of ".something", the script should display the next HTML element regardless of what it is and without interfering with other countdowns. So an easier alternative to what I suggested earlier would be:

Unlike before, the value of "data-toggle" can be "next" for all countdowns as supposed to needing a unique value for each countdown.
