Weekend in Lisbon
Three days of tiles, tarts and trams.
Spotlight Reveal Image Hover
At rest the photo is dark except for a soft spotlight in the middle; hover and the light spreads to the edges. The vignette is one radial gradient that scales up, so only a transform animates.
Also known as: vignette hover effect, flashlight reveal image, vignette fade on hover.

}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.
