Custom CSS

For advanced styling beyond the built-in options, you can add your own CSS in Global settings → Custom CSS. The CSS is loaded on your storefront and applies to the OPTIS Color Swatch elements.

Custom CSS is an advanced feature. Incorrect rules can affect how swatches look. Test on a draft theme first if you are unsure, and keep a copy of your CSS so you can revert.

How to add custom CSS

1

Open Global settings

Go to Global settings and find the Custom CSS section.

2

Write your CSS

Enter your CSS rules in the editor.

3

Save

Click Save. Refresh your storefront to see the result.

Targeting OPTIS elements

The app renders its variant picker inside a custom element. You can target it in your CSS, for example:

/* The OPTIS variant picker wrapper */
optis-variant-picker {
  margin-top: 12px;
}

Most appearance changes (size, spacing, colors, borders, alignment) can be made without code on the Styling page. Use Custom CSS only for adjustments the Styling page does not cover.
