Overview
The upsell arrow in UpCart is black by default. If you set a dark or black background, the arrow may become difficult to see when scrolling through the upsell carousel. To fix this, please copy the following code and paste it into:
UpCart Cart Editor > Settings > CSS.
.styles_PreviewCarousel__ [class~='control-next']::before,
.styles_PreviewCarousel__ [class~='control-prev']::before {
border-color: white !important; }
You are able to change the color to any desired shade by either changing the name of the color (where it currently says white), or by clicking the color swatch next to the color name and selecting your own shade in the popup window.
