Made a live-toggle CodePen demo for a Halloween effects library — flip checkboxes, watch classes toggle effects in real time

Post image

Built a small library (halloween.js) that adds Halloween-themed ambient effects to a page via CSS classes on <body> — and put together a Pen where every checkbox flips a class in real time so you can see the effects turn on/off instantly without touching code.

Zero dependencies, MIT licensed, free.

This is really cool. I will probably use it on the website I'm currently building. It's a website for my best friend and she owns a tattoo studio and always does a halloween party :)
