Theme × Skin Lab

Two independent axes. Themes answer which colors — swap the palette and everything recolors. Skins answer how surfaces are drawn — backgrounds, borders, shadows, inner highlights, blur, radius. Pick one of each; every demo below redraws instantly.

20 themes × 10 skins = 200 looks from 30 files · no rebuild · no reload

How does this work?

One <link> per axis. Skins are token-only files in @layer exsa.skins — no component CSS, no rebuild.

Timeline surfaces follow the skin.

Every value above is computed from --surface-* tokens — the same contract a custom skin uses. Write your own: a ~25-line :root block in @layer exsa.skins, link it, done. Full design →
