Glare Hover

GlareHover is a div-based wrapper that adds a diagonal glare sweep on hover using a CSS pseudo-element and configurable CSS variables. It supports custom dimensions, background and glare colors, opacity, angle, tile size, duration, and hover-only transition behavior.

Usage

usage.tsx
import { GlareHover } from "@/components/ui/glare-hover"export default function Example() {  return (    <GlareHover width="320px" height="200px" className="rounded-xl">      <span className="text-white">Hover me</span>    </GlareHover>  )}
  • Add a polished hover treatment to cards, media previews, product tiles, and feature panels.
  • Emphasize calls to action or clickable visual elements without adding extra markup.
  • Create configurable shimmer or glare effects with a CSS-only pseudo-element.
  • Use different angles, colors, sizes, and durations to match a brand or interaction style.

Examples

Product card

A dark product tile with a purple glare highlight and rounded corners.

product-card.tsx
import { GlareHover } from "@/components/ui/glare-hover"export function ProductCard() {  return (    <GlareHover      width="320px"      height="420px"      background="#18181b"      color="#a78bfa"      opacity={0.35}      className="rounded-2xl border border-white/10 p-6"    >      <div className="flex h-full flex-col justify-end text-white">        <p className="text-sm text-zinc-400">Collection 2025</p>        <h2 className="text-2xl font-semibold">Aurora Pack</h2>      </div>    </GlareHover>  )}

Call-to-action panel

A compact promotional panel with a faster blue glare sweep.

call-to-action-panel.tsx
import { GlareHover } from "@/components/ui/glare-hover"export function UpgradePanel() {  return (    <GlareHover      width="100%"      background="#172554"      color="#bfdbfe"      opacity={0.3}      angle={-35}      duration={500}      className="rounded-xl px-6 py-5"    >      <div className="flex w-full items-center justify-between gap-4 text-white">        <span className="font-medium">Upgrade your workspace</span>        <span className="text-sm text-blue-100">Learn more →</span>      </div>    </GlareHover>  )}

Hover-only transition

A content card whose glare transition is enabled only while the pointer enters the element.

hover-only-transition.tsx
import { GlareHover } from "@/components/ui/glare-hover"export function FeatureCard() {  return (    <GlareHover      width="280px"      height="160px"      color="#ffffff"      opacity={0.2}      playOnce      className="rounded-lg bg-zinc-900 p-5"    >      <div className="text-white">        <h3 className="font-semibold">Fast delivery</h3>        <p className="mt-2 text-sm text-zinc-400">Ship updates with confidence.</p>      </div>    </GlareHover>  )}

API reference

PropTypeDefaultDescription
widthstring | undefinednullOptional CSS width applied to the root div, such as `"100%"` or `"320px"`.
heightstring | undefinednullOptional CSS height applied to the root div, such as `"auto"` or `"200px"`.
backgroundstring | undefined"#000"CSS color string used as the wrapper background.
color`#${string}` | undefined"#ffffff"Hex glare color. Six-digit and three-digit hex values are converted to an rgba color using `opacity`; other `#...` strings are passed through unchanged.
opacitynumber | undefined0.5Opacity used when converting a valid hex glare color to rgba. The source documents the intended range as 0–1 but does not clamp the value.
anglenumber | undefined-45Gradient angle in degrees, assigned to the `--gh-angle` CSS variable.
sizenumber | undefined250Glare tile size as a percentage, assigned to `--gh-size` and used for `background-size`.
durationnumber | undefined650Glare transition duration in milliseconds, assigned to `--gh-duration`.
playOnceboolean | undefinedfalseWhen true, disables the default transition and enables the glare transition only on hover. The prop changes transition behavior; it does not limit the effect to a single lifetime occurrence.
childrenReactNodenullContent rendered inside the root div. Inherited from `ComponentProps<"div">`.
classNamestring | undefinednullAdditional classes merged after the component's built-in classes. Inherited from `ComponentProps<"div">`.
styleCSSProperties | undefinednullInline styles merged into the generated style object. It can customize the background and CSS variables; explicit `width` and `height` props are applied afterward. Inherited from `ComponentProps<"div">`.
...propsReact.ComponentProps<"div">nullAll other native div props, including `id`, `role`, `tabIndex`, event handlers, ARIA attributes, and data attributes, are spread onto the root div.

Accessibility

  • The glare is implemented with a `::before` pseudo-element that has `pointer-events: none`, so it does not block pointer interaction with the content or root element.
  • The component renders a `div`, not a button or link. For an interactive action, provide appropriate semantics and keyboard behavior through div props, or place a semantic interactive element inside it.
  • The visual effect is hover-only and has no built-in keyboard-focus state, so keyboard users will not receive the glare unless a focus style is added through `className` or `style`.
  • The component does not include a reduced-motion media-query adjustment. Consider adding reduced-motion handling when the sweep could be distracting.
