Spiral Stair Ascent
Treads wind up a real CSS 3D helix round a central post, each stepping one slot higher per beat with the top one leading, so the climb never ends. One accent tread rides the whole way up.
Also known as: spiral staircase animation, css 3d helix loader, endless stairs css, isometric spiral stairs.
