Weekend in Lisbon
Three days of tiles, tarts and trams.
Ambient Glow Image Hover
The photo lifts and casts a soft glow in its own colors, like ambient TV lighting. The glow is a blurred, saturated copy of the same background sitting behind it, faded in with opacity.
Also known as: colored shadow image, blurred image shadow, ambilight hover effect.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
