Weekend in Lisbon
Three days of tiles, tarts and trams.
Outline Ring Image Hover
An accent ring springs out around the photo on hover and keyboard focus, with a small gap, while the photo nudges in. It is outline-offset, so the ring takes no layout space and follows the radius.
Also known as: outline offset hover, image border on hover, focus ring image.

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.
