Weekend in Lisbon
Three days of tiles, tarts and trams.
Before and After Image Hover
A flat, unedited version of the photo on the left and the finished one on the right, split by a handle. Hover and the handle sweeps left, wiping the whole frame to the edited shot. No JavaScript.
Also known as: before after slider css, image comparison hover, photo edit reveal.

}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.
