Overview
This tutorial shows how to change the toggle colors used in Upcart’s add-on module, including shipping protection or any product-based toggle. Custom-colored toggles can help highlight important upsells and create a more cohesive visual experience.
This approach is best for store owners or developers with basic CSS knowledge.
Where to find the custom CSS editor
Go to Upcart > Cart Editor > Settings > Custom CSS
Scroll to the bottom of the page and paste the CSS code into the input field
Click Save
Refresh your storefront to see the changes applied
Sample CSS for toggle customization
The CSS below adjusts the toggle background color (on and off states), the toggle handle color, and resets other elements to avoid visual conflicts.
.upcart-cart { --toggleColorWhenOn: #0dcd8d; /* Color when toggle is ON */ --toggleColorWhenOff: #c4cdd5; /* Color when toggle is OFF */ --toggleHandleColor: #ffffff; /* Color of the toggle handle */ } /* Toggle background when OFF */ [class*="styles_ToggleSwitch"] { background-color: var(--toggleColorWhenOff); } /* Toggle background when ON */ [class*="styles_ToggleSwitch--active__"] { background-color: var(--toggleColorWhenOn) !important; } /* Toggle handle (the circle) */ [class*="styles_ToggleSwitch__circle__"] { background: var(--toggleHandleColor) !important; } /* Reset internal parts to avoid unwanted overlap */ [class*="styles_ToggleSwitch__loader__"], [class*="styles_ToggleSwitch__loading__"], [class*="styles_ToggleSwitch__checkMark__"] { background-color: unset !important; }How to customize
You can change any of the --toggleColorWhenOn, --toggleColorWhenOff, or --toggleHandleColor values to match your brand. Use any valid hex code or color keyword.
Example:
--toggleColorWhenOn: #ff6b6b; /* red */ --toggleColorWhenOff: #f3f4f6; /* light grey */ --toggleHandleColor: #000000; /* black */
