Weekend in Lisbon
Three days of tiles, tarts and trams.
Glitch Image Hover
While hovered, color-shifted slices of the photo jump sideways at random-looking intervals, a digital glitch. Two copies with clip-path insets are stepped through keyframes with steps(1).
Also known as: rgb split image, glitch effect css image, distorted image 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.
