Darkness Consuming
About Darkness Consuming
Darkness Consuming is a toggle switch built with a keyframe animation, gradient fills, transforms and layered shadows. Its stylesheet runs to 79 lines across 16 rules, declaring 24 distinct properties. It styles checked state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by a keyframe sequence named void-swirl, which you can retime or remove without touching the rest of the styling. Every format shown on this page is the same component, so you can take CSS and Tailwind depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- Preference screens, where the control is switched more often than it is read, where a horror and dark toggle switch fits the surrounding design
- A single prominent toggle switch rather than a row of them, since the void-swirl animation runs continuously and several at once compete with each other
- Palettes built around black, purple and void, where this toggle switch can be dropped in without retheming
- Places where one control is meant to be memorable, since 79 lines of CSS is a real investment for a single element
How it works
The base rule sets the shape with border-radius, display, height and position. The fill is a gradient rather than a flat colour, so it is a single background declaration with no image to load. Movement is done with transforms rather than by changing position or size, which is what keeps it smooth: transforms are composited and do not force the browser to lay the page out again. State changes are eased with a transition, so hovering does not snap. The looping motion comes from void-swirl. Changing the animation-duration is usually the only edit needed to make it faster or calmer.
Accessibility
No focus style is defined. Add one before shipping, or keyboard users lose track of position. Animates without a prefers-reduced-motion guard. Wrap the animation in that query if motion sensitivity matters to your audience. Those are 2 things to fix before this ships in front of users.
Browser support
Everything this component uses has been supported across browsers for years, so no fallback is needed.
