Overview

FeatureCard is a promotional content block designed for landing pages, feature grids, and marketing sections. It presents an icon, heading, and description in a vertical layout with a polished gradient border hover effect that draws attention without overwhelming the content. The card's animated hover state includes an icon lift, a subtle glow from `--glow-card-hover`, and an expanding accent rule that creates a premium feel. When an `href` is provided, the entire card renders as an anchor element, making it a natural fit for feature grids that link to detail pages. Without an href, it renders as a static `<div>`, suitable for purely informational feature lists. The card uses a 1px padding trick with a gradient background to produce a border effect that transitions smoothly on hover. The icon slot accepts custom content (SVG icons, emoji, or any markup) via the `icon` named slot, falling back to the `icon` string property for simple text or emoji icons. CSS parts (`card`, `inner`, `icon`, `title`, `description`) are exposed for deep style customization when needed.

Guidelines

When to use

Use in a CSS grid for feature grids — the card fills its height via flex layout
Provide an href when the card should navigate to a detail or docs page
Keep descriptions concise (one to two sentences) for scannable feature lists
Use the icon slot for SVG icons when you need precise sizing and color control
Combine multiple feature cards in a 2- or 3-column grid for landing page sections

When not to use

Do not nest interactive elements (buttons, links) inside a feature card that already has an href
Do not use long paragraph-length descriptions — the card is designed for brief summaries
Do not mix feature cards with value cards in the same grid — choose one style per section
Do not override the gradient border with a flat color — it loses the signature hover effect
Do not use feature cards for data display — use value cards or stat components instead

Features

Gradient border hover effect using a 1px padding technique for smooth transitions
Icon slot with fallback to the icon string property for simple emoji or text
Renders as an <a> when href is set, or a <div> for static display
Animated icon lift with glow shadow (`--accent-primary-glow`) on hover
Expanding accent rule that fades in on hover for visual polish
Focus-visible outline using `--focus-glow` for keyboard navigation
Responsive padding that adjusts at the 768px breakpoint
CSS parts (card, inner, icon, title, description) for external styling

Usage

Feature Card is in the marketing domain group, so it is deliberately absent from the default @arclux/arc-ui barrel. Import it from @arclux/arc-ui/marketing, or from its own subpath @arclux/arc-ui/feature-card. Everything else — the element, the CSS, the framework wrappers, the support it gets — is unchanged.

<arc-feature-card
  heading="Performance"
  description="Optimized builds for lightning-fast load times."
></arc-feature-card>

import { FeatureCard } from '@arclux/arc-ui-react';

export default function Example() {
  return (
    <FeatureCard
      heading="Performance"
      description="Optimized builds for lightning-fast load times."
    />
  );
}

<script setup>
import { FeatureCard } from '@arclux/arc-ui-vue';
</script>

<template>
  <FeatureCard
    heading="Performance"
    description="Optimized builds for lightning-fast load times." />
</template>

<script>
  import { FeatureCard } from '@arclux/arc-ui-svelte';
</script>

<FeatureCard
  heading="Performance"
  description="Optimized builds for lightning-fast load times." />

import { Component } from '@angular/core';
import { FeatureCard } from '@arclux/arc-ui-angular';

@Component({
  imports: [FeatureCard],
  template: `
    <arc-feature-card
