Custom CSS / JS Manager is a powerful PrestaShop module that allows merchants, developers, and agencies to add custom CSS and JavaScript directly from the back office with a clean and user-friendly interface.

Why use a Custom CSS / JS Manager?
In many PrestaShop stores, even small frontend changes often require editing theme files, accessing FTP, or modifying code manually. This can be risky, time-consuming, and difficult to maintain — especially after theme updates.
With this module, you can:
- Add custom CSS styles without editing theme files
- Insert JavaScript snippets safely from the admin panel
- Control where and when scripts are loaded
- Manage all custom frontend code in one centralized place
- Reduce the risk of breaking your website during updates
Perfect for store owners, marketers, developers, and agencies who need flexibility without complexity.
