Apologies for the inconvenience. Unfortunately, there is currently no built-in setting in the Image Layout addon to change the column ratio from col-sm-6 / col-sm-6 to col-sm-4 / col-sm-8.
However, you can achieve this using custom CSS. Please add the following CSS in your Addon's Style tab → Custom CSS field (as shown here: https://prnt.sc/U3aEZZnz2cuc):
@media (min-width: 992px) {
#addonId .sppb-row > div:first-child {
flex: 0 0 33.333333%;
max-width: 33.333333%;
}
#addonId .sppb-row > div:last-child {
flex: 0 0 66.666667%;
max-width: 66.666667%;
}
}
This will make the image section take 4 columns (33.33%) and the text/content section take 8 columns (66.67%) on larger screens.
If you need further assistance, please feel free to let us know.
