Accessibility check2 to fix

  • 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.

Browser support notes

  • Backdrop filter needs a -webkit- prefix on older Safari.

These notes are generated by reading this component's own source, so they describe what it actually does rather than what a template says. Copy the code above in HTML, CSS, Tailwind and adapt it freely.

About Quantum Energy Card

Quantum Energy Card is a card built with a keyframe animation, gradient fills, transforms, layered shadows and a blurred backdrop. Its stylesheet runs to 463 lines across 80 rules, declaring 45 distinct properties. It styles hover state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by keyframe sequences named quantum-grid, spin, pulse and ping, 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

How it works

The base rule sets the shape with border-radius, display, height and margin. 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 quantum-grid, spin, pulse and ping. 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.

Native element semantics, no extra attributes needed

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.
