Stencil is BigCommerce’s theme engine. It incorporates industry best practices in technology, design standards, SEO, and allows developers to build a stunning storefront that engages shoppers and encourages checkouts on any device. Stencil themes are supported on the following browsers. Stencil is responsible for powering the BigCommerce Cornerstone theme.
The Store Design tool available on Stencil themes allows merchants to customize a storefront’s look and feel with no coding, making customizations possible by a wide range of users. Store Design enables quick and easy customization of a theme’s colors, typography, banners, headings, carousel, and footer. It also enables customization of a storefront’s layout characteristics, such as the number of products displayed in various panels, category pages, and brand pages. For details, see Personalizing Your Theme (BigCommerce Knowledge Base).
BigCommerce Stencil themes are responsive, mobile friendly themes, allowing shoppers to have a first class experience across any device. Each Stencil theme can contain one to four variations. You can optimize individual variations for specific markets, audiences, and styles, while still managing and distributing all of these variations as one theme.
Cornerstone comes in three, fully-responsive variations:
- Cornerstone Light
- Cornerstone Warm
- Cornerstone Bold
See the Cornerstone Light theme demo to experience a Stencil theme’s capabilities.
As the default theme on new stores, Cornerstone is typically the first theme to support new theme-related features and improvements. See the BigCommerce Developer Changelog for the latest Cornerstone news and release notes.
The Stencil CLI enables developers to locally develop and customize on any Stencil theme with no impact on a merchant’s live storefront during the development process. When developing locally, developers have access to real-time Browsersync preview and testing across desktop, mobile, and tablet devices/viewports.
Stencil’s logic based templates allow BigCommerce developers to customize storefront pages efficiently with the lightweight templating language, Handlebars.js. Handlebars.js allows you to efficiently embed dynamic and conditional logic onto your storefront pages.
Powerful CSS Stack
Stencil themes support both Sass and SCSS. Developers can use these popular CSS pre-processors to nest CSS properties, variables, and mix-ins.
Foundation assets are located in the following directories:
Stencil’s use of YAML Front Matter allows developers to request only the objects needed on the storefront, increasing page speed and allowing developers to define the content to render with just a few keystrokes.
Stencil themes can access remote objects through event hook and use the hooks to trigger defined events based on shopper behavior. This will allow you to collect product data and optimize a shopper’s experience. To facilitate theme-building, BigCommerce provides stencil-utils – a client-side library for managing event hooks.
