Custom CSS

For styling that Styling cannot express.

When to use it

When you have tried tokens and they genuinely cannot do what you need. That is a smaller set of cases than it first appears.

The editor

Write CSS with a live preview, including unsaved changes. Save to apply.

What can break

Caution

Custom CSS targets the storefront’s markup. When Rubikc changes that markup, your CSS can stop working or start doing something unintended — and nothing will warn you.

Two habits reduce the pain:

• Keep it small. Every rule is one you may have to fix later.
• Check after Rubikc updates, particularly if something looks subtly wrong.
