It's 2 classes, but I think here the idea is not so much "nested" as
"both".
So the rule with .ng-hide-add.ng-hide-add-active will be applied to classes
that have both classes.
You had the following CSS rules:
.ng-hide-add.ng-hide-add-active,
.ng-hide-remove {
opacity: 0;
}
.ng-hide-add,
.ng-hide-remove.ng-hide-remove-active {
opacity: 1;
}
So <div class=''.ng-hide-add"> matches the second rule and will have
opacity 0.
<div class=''.ng-hide-add .ng-hide-add-active"> matches the first rule and
will have opacity 1.
