Animations

There are two animation props: "initialAnimation"—triggered after each source's load, and "slideChangeAnimation"—triggered after a slide change (but not after a slide change through swiping). Their values ought to be CSS classes. Both props can't contain the same CSS class simultaneously (the animations won't work properly).

An example:
CSS:

.example-initial-animation {
	animation: initial-animation 2s ease;
}

@keyframes  initial-animation {
	0% {
		transform: rotate(0deg);
	}

	50% {
		transform: rotate(360deg);
	}

	100% {
		transform: rotate(0deg);
	}
}

fsLightboxInstances["gallery"].props.initialAnimation = "example-initial-animation";
