</div>About Rainbow Prism Input
Rainbow Prism Input is a input field built with a keyframe animation and gradient fills. Its stylesheet runs to 50 lines across 9 rules, declaring 15 distinct properties. It styles focus state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by a keyframe sequence named gradientShift, 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, CSS and Tailwind depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- A single prominent input field rather than a row of them, since the gradientShift animation runs continuously and several at once compete with each other
- Palettes built around red, blue and yellow, where this input field can be dropped in without retheming
- Places where one control is meant to be memorable, since 50 lines of CSS is a real investment for a single element
How it works
The base rule sets the shape with border-radius, display, 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. State changes are eased with a transition, so hovering does not snap. The looping motion comes from gradientShift. Changing the animation-duration is usually the only edit needed to make it faster or calmer.
Accessibility
Built on a native <input> element, so keyboard focus and screen reader semantics work without extra attributes. Defines a focus style for keyboard navigation. Animates without a prefers-reduced-motion guard. Wrap the animation in that query if motion sensitivity matters to your audience. That is one thing 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.
