“The Impossible Light Bulb” is a playful and unexpected user interaction where a bulb appears clickable—but it never lights up, no matter how many times the user tries. Built using HTML, CSS, and JavaScript, this mini-project is perfect as a humorous Easter egg, a fun addition to a UI playground, or as a light-hearted JavaScript exercise.
The button, bulb, and feedback messages work together to build suspense, only to deliver a cheeky surprise.
HTML5 – Light bulb structure and toggle button
CSS3 – Bulb style, glow animation, and fake transitions
JavaScript – Tracks clicks, adds logic for misdirection, prevents actual toggle
The UI displays a light bulb and a switch that appears functional. When the user clicks the switch, JavaScript intercepts the click and plays a small fake animation (like a flicker or bounce). CSS may show a quick glow or flash, giving the illusion it might light up. However, the bulb always returns to the “off” state. Behind the scenes, JavaScript intentionally avoids activating any “on” logic, creating a looping illusion of broken functionality. After a few attempts, humorous messages may appear, teasing the user or giving up hope.
