How this works

A single .cs-04__glow element is absolutely positioned and translated with transform: translateY() to sit behind whichever option is active, creating a sliding highlight that never triggers layout. Each tier's orb is a distinct radial-gradient so Starter, Pro, and Enterprise read at a glance.

The price is emphasized with a larger tabular figure while the cadence (/mo) is de-emphasized. On selection the trigger adopts the tier's accent color through a CSS variable set inline by the cs:pick handler.

Make it yours

  • Retune each tier orb by editing the --o1..--o3 gradient variables.
  • Change the glide speed with the transition on .cs-04__glow.
  • Swap currency by editing the price strings in the markup.

Gotchas — read before shipping

  • The sliding glow assumes equal-height rows; if you add multi-line descriptions, switch it to match each row's measured offset.
  • Announce price changes to assistive tech with an aria-live region if the price drives a live total elsewhere.
