Understanding Themes

Themes allow you to customize the look and feel of BigCommerce stores. The compelling store designs in the BigCommerce Showcase demonstrate the kinds of things that can be done.

To ensure that your themes make the most of BigCommerce’s extensive out-of-the-box features and capabilities, please be aware of all the supported features that store owners manage and maintain through the BigCommerce control panel.

You can ask further questions, and seek advice, in the Developer Forum. For professional assistance in customizing a theme, consider hiring a BigCommerce Expert.
