A row of outlined round social buttons whose fill rises from the bottom like liquid, with a domed edge that rolls as it climbs. One oversized pseudo-element per link.
Also known as: social media icons hover effect, social buttons fill on hover, footer social icons css.

Currently previewing #3b82f6.--hfx-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 16px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
