Its calculators come from a set I built for the group, including a carbon calculator, a tank size calculator and volume converters. Each one is an HTML custom element, built once and embedded on whichever sites need it, and takes its colours from the theme of the site it’s on.
Like every site in the group, it’s a custom WordPress theme, front end and back end, built from scratch. It runs on a back-end library I wrote and share across all of the sites, which handles form submissions, phone and email verification and common utilities. Front-end assets are bundled with Vite, and the sites are hosted on AWS behind Cloudflare: I moved the whole group onto Cloudflare and tuned its caching, which made the sites far more reliable.
