Emoji Reaction Bar Hover
Hover the Like button and a bar of six reactions pops up above it, each emoji springing in a few milliseconds after the last. Hovering an emoji lifts and enlarges it.
Also known as: facebook reactions css, reaction picker on hover, emoji popup on 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.
