Cornerstone is a free theme designed by BigCommerce and is available to all stores. It is fully responsive, meaning it automatically adapts to the device it is being viewed on (desktop, tablet, or mobile), and has built-in features to help you sell, like a homepage carousel (slideshow), social media icons, featured, top-selling, and new product panels, and support for product filtering (faceted search).
The theme has a simple and clean design that can be easily customized to match your business or brand using the Page Builder.
Cornerstone Theme Features
The Cornerstone theme comes with three style variations that are each fully responsive and ideal for a large catalog. The theme utilizes a top navigation and buttons with rounded corners.
For Carousel slide images, we support JPEG, GIF, and PNG file types, but recommend using JPEG files for product images to ensure a balance between image quality and fast loading time. We also recommend using slide images approximately 1400 x 600 pixels or 1400 x 800 pixels. All slide images should have consistent dimensions.
You can resize your store product images by adjusting the product card dimensions in Page Builder. When you are resizing your images, it is best to keep them all the same aspect ratio. For more information, see our guides on Troubleshooting Your Store Images and Adjusting Your Store Image Settings.
Updates and customer support for the Cornerstone theme are provided for free. However, BigCommerce technical support is unable to directly assist with editing code like HTML or CSS. See the BigCommerce Design Policy for more information.
Localized Store Experiences: This feature is available for all of our supported languages. For more information on the default language store setting, see Store Profile Settings.
Release Notes
As the default theme on new stores, Cornerstone is typically the first theme to support new theme-related features and improvements.
See the Dev Center Updates for the latest Cornerstone release notes.
