Modern CSS Gradient Effects

Animated, mesh, conic and text gradients built from the theme colours.

Northern-lights colour clouds that drift inside a card and brighten when it is hovered. Class: fx-aurora-hover

Dark mode

We measure success by how many customers come back and tell their friends.

<div class="flex flex-wrap items-center justify-center gap-4 p-4 h-full" style="min-height:200px">
  <div class="card fx-aurora-hover" style="width:15rem">
    <div class="card-body">
      <h3 class="h6 font-bold mb-1">Dark mode</h3>
      <p class="small text-muted mb-2">We measure success by how many customers come back and tell their friends.</p>

2Color Morphing

Smoothly cycles a background and its glow through the theme colours - nice for badges and CTAs. Class: fx-color-morphing

<div class="flex flex-wrap items-center justify-center gap-4 p-4 h-full" style="min-height:200px">
  <button type="button" class="btn btn-lg border-0 rounded-full fx-color-morphing">Reserve a spot</button>
  <div class="fx-color-morphing rounded-full grid text-2xl" style="width:72px;height:72px;place-items:center">
    <i class="bi bi-lightning-charge-fill" aria-hidden="true"></i>
  </div>
</div>

/* CSS (already in assets/css/effects.css) */
.fx-color-morphing { color: var(--wt-on-primary, #fff); background-color: var(--wt-primary); animation: fx-color-morphing-morph 6s ease-in-out infinite; }
@keyframes fx-color-morphing-morph {
  0%, 100% { background-color: var(--wt-primary); box-shadow: 0 10px 24px -10px rgba(var(--wt-primary-rgb), .8); }
  33% { background-color: var(--wt-accent); box-shadow: 0 10px 24px -10px rgba(var(--wt-accent-rgb), .8); }
  66% { background-color: var(--wt-secondary); box-shadow: 0 10px 24px -10px rgba(var(--wt-secondary-rgb), .8); }
}
@media (prefers-reduced-motion: reduce) {
  .fx-color-morphing, .fx-color-morphing::before, .fx-color-morphing::after, .fx-color-morphing *, .fx-color-morphing *::before, .fx-color-morphing *::after { animation: none !important; transition: none !important; }
}

A colourful multi-tone glow under cards and images built from layered tinted shadows. Class: fx-gradient-shadow
