Developer docs
Zero is a theme and a set of modules for Magento Open Source 2.4: server-rendered HTML, HTMX and Tailwind CSS, no RequireJS, jQuery or Knockout. These pages are the same docs that ship in the theme's docs/ folder.
Building the CSS and JavaScript
The pipeline: Tailwind and the module styles, the plain JS files, the commands, when to rebuild, the deploy.
ReadExtensions on Zero
Module styles, JavaScript rules, compat modules for third-party extensions, pages on another theme, and the building blocks Zero_Core offers.
ReadChild themes
A store's own look on top of Zero: tokens, overrides, templates, deployment.
ReadComponent library
Every UI component rendered live with its code, at /zero/ui/ on a Zero store.
ReadPerformance
What the PageSpeed score rests on, the budgets, what to keep to when adding a module, a theme or content, and how to check before a deploy.
ReadZero CMS
Pages built from components in the admin editor, with revisions, preview and an AI writer.
ReadZero Blog
Posts, categories, tags, authors, comments, RSS and imports from WordPress, Magefan and Amasty.
