The halloween body class turns the whole library on. Without it nothing runs. How it combines with the season window.
<body class="halloween"> turns the library on. Without this class
nothing runs at all: no ambient effects, no screen corners, no badge. Every other
class is only a modifier.
<body class="halloween">Values#
| Class | Effect |
|---|---|
halloween |
On. The other classes and attributes take effect. |
| not present | Off. Everything is removed from the page, including effects already on screen. |
What it affects#
- Every ambient effect, every screen corner and the badge are gated by it.
- It is the first of two gates. The second is the season window: the library does anything only when the class is present and today is inside the season. Both are checked together each time something changes.
Changing it at runtime#
Adding or removing the class is picked up automatically. Removing it removes the web corners, the badge and every effect on screen immediately, and stops the timers that create new effects.
document.body.classList.add("halloween");
document.body.classList.remove("halloween");
<body> is the only element that is watched. The class on
<html> or on any other element has no effect.
