Circuit — Shopify Theme

▶ View live demo
Opens this theme running on our store with real products.

Circuit is built like a piece of lab equipment. Void-black canvas, instrument-white type, a single signal-blue accent, and hairline rules that behave like a measurement grid. Headings run in Space Grotesk while every label, price and spec line sits in IBM Plex Mono — so numbers read as data, not decoration.

The product page is the centrepiece. A repeatable specification sheet lets you add as many label/value rows as your unit needs, alongside trust badges, a price pill, a thumbnail gallery and a variant picker that swaps price, image, availability and the URL live. Related products sit underneath as an on/off block.

You get 24 sections across 20 templates — home, collection, product, cart, search, blog, article, pages, contact, collection list, 404, password and the full customer account set. Every headline, eyebrow, count word, empty state and button label is editable in the theme editor; nothing is hardcoded into the Liquid.

Written from scratch — one stylesheet, one small script, no framework and no jQuery. Quick-add and the variant picker are progressive enhancement: with JavaScript off, they fall back to plain form posts. An empty development store still renders complete demo content, so you can shape the layout before your catalog lands.
