Modern CSS Filter Effects

Grayscale, blur, hue, sepia, duotone and glow filters for photos, logos, icons and text.

1Blur Focus

Put it on a row of cards or images: the hovered item stays sharp while its siblings blur and fade. Class: fx-blur-focus

<div class="d-flex flex-wrap align-items-center justify-content-center gap-3 p-3 h-100" style="min-height:200px">
  <div class="fx-blur-focus d-flex gap-2">

/* CSS (already in assets/css/effects.css) */
.fx-blur-focus > * { transition: filter .4s ease, opacity .4s ease, transform .4s ease; }
.fx-blur-focus:hover > :not(:hover) { filter: blur(3px) saturate(.6); opacity: .65; }
.fx-blur-focus > :hover { transform: translateY(-4px); }
@media (prefers-reduced-motion: reduce) {
  .fx-blur-focus, .fx-blur-focus::before, .fx-blur-focus::after, .fx-blur-focus *, .fx-blur-focus *::before, .fx-blur-focus *::after { animation: none !important; transition: none !important; }
}

2Glitch Filter

Short bursts of hue, contrast and position jumps make an image look like a corrupted signal. Class: fx-glitch-filter

<div class="d-flex flex-wrap align-items-center justify-content-center gap-3 p-3 h-100" style="min-height:200px">

.fx-glitch-filter { animation: fx-glitch-filter-glitch 3.5s steps(1) infinite; }
@keyframes fx-glitch-filter-glitch {
  0%, 86%, 100% { filter: none; transform: none; }
  88% { filter: hue-rotate(90deg) saturate(3) contrast(1.6); transform: translate(-4px, 1px); }
  90% { filter: invert(.15) contrast(2); transform: translate(4px, -2px) skewX(6deg); }
  92% { filter: hue-rotate(-70deg) saturate(2); transform: translate(-2px, 0); }
  94% { filter: brightness(1.6); transform: translate(2px, 1px); }
