Prismatic Button
<button class="prismatic-btn">Prismatic</button>About Prismatic Button
Prismatic Button is a button built with a keyframe animation, gradient fills, transforms, layered shadows, a blurred backdrop and pseudo elements. Its stylesheet runs to 32 lines across 4 rules, declaring 20 distinct properties. It styles hover state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by a keyframe sequence named prismatic-rotate, 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 HTML and CSS depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- Marketing pages and hero sections, where the fill is part of the visual identity, where a gradient and prismatic button fits the surrounding design
- A single prominent button rather than a row of them, since the prismatic-rotate animation runs continuously and several at once compete with each other
- Palettes built around rainbow and transparent, where this button can be dropped in without retheming
- Layouts with imagery or colour behind the control, since the backdrop blur needs something to blur
How it works
The base rule sets the shape with border-radius, height, padding and position. The fill is a gradient rather than a flat colour, so it is a single background declaration with no image to load. A pseudo element carries part of the effect, which keeps the markup to one element while giving the CSS a second surface to animate. 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 prismatic-rotate. Changing the animation-duration is usually the only edit needed to make it faster or calmer. The backdrop filter blurs whatever sits behind the element, which means the effect depends on the page underneath rather than on the component alone.
Accessibility
Built on a native <button> element, so keyboard focus and screen reader semantics work without extra attributes. 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
Backdrop filter needs a -webkit- prefix on older Safari.
