Subscription box builder

Builds a recurring product box with item limits, frequency, price, and a persistent order summary. Add and remove controls enforce the item limit and announce current count and recurring total. Frequency and recurring cost remain visible throughout composition rather than only at checkout.

Implementation field notes

Use subscription box builder confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Product detail pages
  • Cart flows
  • Customer accounts

This subscription commerce pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • Interactive targets use labelled native controls and retain a visible focus treatment.
  • State, totals, filtering, and errors are communicated with persistent text instead of color alone.
  • The layout reflows without changing the semantic reading order, and motion respects reduced-motion preferences.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt primary accent, secondary accent, surface color, text color through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
