Weekend in Lisbon
Three days of tiles, tarts and trams.
Caption Reveal Card
A caption panel slides up over the image on hover, the classic portfolio and gallery treatment. The panel is inside the image frame so it never changes the card's height.
Also known as: image overlay hover, slide up caption, portfolio 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.
