Modern CSS Filter Effects
Grayscale, blur, hue, sepia, duotone and glow filters for photos, logos, icons and text.
1Grayscale to Color
Keeps images black and white until they are hovered or focused - ideal for logo walls and team grids. Class: fx-grayscale-to-color
<div class="d-flex flex-wrap align-items-center justify-content-center gap-3 p-3 h-100" style="min-height:200px">

Continuously cycles the colours of a gradient, illustration or image through the colour wheel. Class: fx-hue-rotation
