Thanks. We already have something similar to this in the current-visible fragment style. A current-visible fragment will appear when it is the current fragment, and disappear again as soon as you move to a another fragment.

What you are proposing seems like the same thing, but instead of just fading in and out it would collapse via display none. That said, what do you think about implementing this as "fragment current-display" (As in "only display when it is the current fragment")?

All the CSS this would take is:

.fragment.current-display:not(.current-fragment) {
	display: none;
}

A simpler CSS for sure! would it support various containers (p, div, pre, etc.?)
