Your problem
My problem is: I cannot get a background color into “Text” containers at top & bottom of “Code Mode” container.
These errors are showing in the log: None
Steps I have tried to fix the problem: Adding code to the text box as a “customize Slot” addition - but to no avail. When I test the email I have a white band down the left side and the text containers are still white rather than #FFF2E6.
