Themes shape the online store experience for merchants and their customers. Build fast, flexible themes at scale using Liquid, Shopify's theme templating language, along with HTML, CSS, JavaScript, and JSON.
Shopify themes are a package of template files, building blocks, and supporting assets. Use these building blocks to create modular, customizable themes.
The Liquid templating language is the backbone of Shopify themes, and is used to load dynamic content on storefronts. Extend Liquid objects to store and present custom data using metafields.
To optimize your theme development experience, Shopify has established a set of best practices that you can refer to when developing your theme and setting up your toolchains and processes.
Learn about the endpoints that Shopify provides to interact with your theme.
Review our AJAX API that lets you update page content without reloading an entire page.
Consult this interactive reference guide to the Liquid template language.
Build Shopify themes faster with this library of ready-to-use Liquid components.
Dawn is our vision for the next generation of Shopify themes. Browse the code on GitHub, then use it as a starting point to build your own theme.
Make your theme more flexible and easier to maintain by migrating it to the new architecture. Using Online Store 2.0, you can add and remove sections from any template, and prepare your theme for [app blocks](/docs/apps/build/online-store/theme-app-extensions).
Shopify provides a range of tools to help you to collaborate and build themes faster.
Initialize, preview, test and share themes in your local development environment.
Integrate GitHub into your Shopify admin to manage your theme code.
Detect errors and enforce best practices as you code, or as part of your CI pipeline.
Design beautiful, purpose-built themes for different markets, and sell them to millions of merchants on the Shopify Theme Store.
