# Customization Gallery
We provide customisations at **No Additional Cost.** You can check out some of our implementations in the [**Customization Gallery**](https://spa.spicegems.com/layouts) section.
There are two types of customisations:
1. **Design Customisation (CSS)**: Addon Layouts can be designed using the Custom CSS.
2. **Feature Customisation (JS + CSS)**: Can be implemented using Custom JS code and CSS. These customisations are Theme structure Dependent; we need to review the Custom JS code compatibility with the theme.
