# Customize
This feature is available only in the PRO version. Which helps custom style for extra custom fields (on the option set).
It helps you customize the style of custom fields such as tabs: **General, Swatches, Button,** and **Custom CSS.**
**General**
In this tab, you can customize the font size and font weight for the Label, total price, and subtotal price.
And the result:
Label and Extra subtotal / Total style
**Swatches**
This is the Swatches tab which allows custom style for the Swatches option.
**Button**
This is the Button tab which allows custom style for the Button option.
**Custom CSS**
This is the Custom CSS tab which allows the customization of styles to the options.
In the following screenshot, we applied a **50% wrap** size to the fields:
**Before,** by default, it was at 100%:
**After applying** the CSS, it was reduced to 50%:
