Weekend in Lisbon
Three days of tiles, tarts and trams.
Square to Circle Image Hover
A square thumbnail turns a quarter of a turn as its corners round off into a circle, while the photo inside counter-rotates and zooms so it stays level. The wrapper never moves, so hover is steady.
Also known as: rounded image hover, border radius morph, avatar circle hover.

}Tailwind CSS version
The same effect using Tailwind utility classes. No custom CSS or config needed.

</div>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.
