Weekend in Lisbon
Three days of tiles, tarts and trams.
Split Image Hover
The photo is cut down the middle and the two halves slide apart on hover to reveal a caption behind them. Each half shows its side of one background, sized to 200 percent.
Also known as: image split in half hover, doors open image reveal, split reveal 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.
