Storefront Architecture

Storefront architecture posts cover themes, Liquid, Online Store 2.0, and structured catalogue data. For theme files that have left Shopify's documented model, read [*Shopify theme customisation limits*](/blog/post/shopify-theme-customisation-limits-when-your-store-leaves-the-supportable-path/). For keyboard, contrast, and label failures, see [*Shopify accessibility bugs that block WCAG AA*](/blog/post/how-to-fix-shopify-accessibility-bugs-that-block-wcag-aa/). For soft navigation with Shopify's Liquid partial tag (header and footer once, main content swaps on in-theme links), read [*Liquid partials without reloading header and footer*](/blog/post/shopify-liquid-partials-swap-main-content-without-reloading-header-and-footer/). For combined **metaobject filters and storefront search** returning zero results, see [*How to Fix Metaobject Filters Combined with Storefront Search*](/blog/post/how-to-fix-metaobject-filters-combined-with-storefront-search-on-shopify/). For delivery, see [Shopify theme development](/services/shopify-theme-development/).
