Bloom

Medium

Three soft fields clustered right of centre, accent over ink, opening and closing against each other.

“Copy the hero” is the styles and the SVG, carrying the colours and speed you set above. “Copy as a section” adds the wrapper a hero actually needs: the SVG absolute behind the copy, inert to the pointer, and a scrim so the heading holds. The Free licence asks for one visible credit per page: Animation by Pulsar, linked to Pulsar. Licence

The four variables

Set any of these on the section, or on any ancestor, and the hero follows. Nothing else in the file needs editing.

--pulsar-hero-bg
the ground, default #f7f7fb
--pulsar-hero-ink
the strokes, default #1d1b3a
--pulsar-accent
the accented strokes
--pulsar-hero-speed
a rate: 2 is twice as fast, 0.5 half speed
