Weekend in Lisbon
Three days of tiles, tarts and trams.
Lightbox Icon Image Hover
An accent tint washes over the photo and a round magnifier button spins in with a small overshoot, the usual cue that a click opens a lightbox. The icon is inline SVG.
Also known as: image hover with icon, zoom icon overlay, gallery plus icon 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.
