# Use Custom CSS Code

|| Custom CSS changes may affect your card's appearance and behavior. Make sure you understand the code before adding it.

Custom CSS lets you adjust parts of your digital business card beyond the options in the default editor. Use it only if you understand HTML and CSS, as custom code can change elements that the standard editor doesn't cover.

## Steps

1. Open the digital business card you want to edit.
2. Go to the **Design** section of your card.
3. Switch to **Extend editor**.
4. Scroll down to **Custom CSS**.
5. Enter your CSS code in the **Custom CSS** field.
