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">

}3Text Filter Effects
Headings come into focus from a blur with a coloured drop shadow - a cinematic title reveal. Class: fx-text-filter-effects
Taste the city's favourite kitchen
<div class="d-flex flex-wrap align-items-center justify-content-center gap-3 p-3 h-100" style="min-height:200px">
