# Custom CSS

### Custom CSS

The Custom CSS option lets you extend the design of your store by adding your own styles. This feature is useful if you want to apply unique adjustments that aren’t available in the default theme settings, giving you complete control over the look and feel of your storefront.

To add your custom CSS to your store:

1. In the theme editor (**Customize**), click T**heme settings.**
2. Locate **Custom CSS.**
3. Enter your CSS rules in the provided editor.
4. Save changes and refresh your storefront to see the updates.
