Why Can’t I Keep My Css Big Commerce

CSS Programming

As a web developer who has worked extensively with different e-commerce platforms, I understand the frustration you may be experiencing when it comes to customizing the CSS on BigCommerce. In this article, I will delve into the reasons why it can be challenging to keep your CSS on BigCommerce and provide some insights into why this platform may not be as flexible as you would like.

The Limitations of Customizing CSS on BigCommerce

BigCommerce is a popular e-commerce platform known for its user-friendly interface and robust features. However, when it comes to customizing the CSS, there are some limitations that users often encounter.

1. Platform Constraints

BigCommerce is a hosted platform, which means that the underlying infrastructure is managed by the BigCommerce team. While this can be advantageous in terms of security and reliability, it also means that you have limited access to the server-side configuration and file system.

This limitation can make it challenging to make extensive changes to the CSS files or override the default styles. The platform’s architecture is designed to provide a consistent user experience across all stores, and as a result, it restricts certain modifications that could potentially lead to inconsistencies or conflicts.

2. Theme Limitations

BigCommerce offers a range of themes that users can choose from to customize the appearance of their online stores. These themes come with pre-defined CSS stylesheets that determine the overall look and feel of the site.

While you can make minor tweaks to the CSS within the theme editor, making more significant changes or creating a completely unique design can be challenging. This is because the themes are built to be compatible with various devices and screen sizes, and modifying the CSS extensively may disrupt this responsive behavior.

Workarounds and Solutions

Although there are limitations to customizing CSS on BigCommerce, there are some workarounds and solutions that you can explore to achieve the desired look for your online store.

1. Customizing Within Theme Editor

Within the theme editor, you can customize certain aspects of the CSS, such as fonts, colors, and spacing. This can be done using the built-in options or by directly editing the CSS code within the editor.

While this method may not give you complete control over the appearance of your store, it provides a middle ground for making minor adjustments without compromising the overall functionality and responsiveness of the theme.

2. Code Injection

Another workaround is to use the code injection feature provided by BigCommerce. This allows you to add custom CSS or JavaScript code directly into specific pages or sections of your store.

By leveraging this feature, you can target specific elements or sections of your site and apply custom styles. However, it’s important to exercise caution and thoroughly test any changes made through code injection to ensure compatibility and maintain the desired user experience.

3. Custom Development

If the built-in customization options are not sufficient for your needs, you may consider hiring a developer who specializes in BigCommerce to help you with custom development. This can involve creating a custom theme from scratch or modifying an existing theme to meet your specific requirements.

A skilled developer can work closely with you to understand your design preferences and implement a tailored solution that aligns with your branding and functionality goals.


Although customizing the CSS on BigCommerce can be challenging, it’s important to keep in mind that the platform offers a range of features and tools that enable you to create a visually appealing and functional online store. While there may be limitations, there are also workarounds and solutions available to achieve your desired customization.

Whether you choose to work within the theme editor, utilize code injection, or seek custom development, it’s crucial to strike a balance between customization and maintaining a consistent user experience. By leveraging the available resources and exploring the options, you can create a unique online store that showcases your brand and resonates with your target audience.
