# Custom CSS Documentation

If you want full control over styling, you can use Custom CSS together with the app’s exposed CSS variables.

Full documentation is available here:

[https://rubikswatch.com/docs/custom-css](https://rubikswatch.com/docs/custom-css)

The documentation includes:

* A complete list of 70+ CSS variables grouped by category
* Variable explanations and usage examples
* HTML structure overview for Image, Button, and Dropdown swatches
* Common customization patterns such as custom borders, hover effects, typography overrides, and layout tweaks
* A quick reference section for fast implementation

Custom CSS is applied per product group and scoped safely, so you can create advanced designs without affecting the rest of your theme.
