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="flex flex-wrap items-center justify-center gap-4 p-4 h-full" style="min-height:200px">
<div class="fx-blur-focus flex gap-2">
