Making a campaign's background transparent or changing the template image may be useful when creating custom campaigns. This will require identifying where a campaign's background images can be changed or removed.
The theme tab
The theme tab is the place to edit campaigns at the lower level, edits here will affect all the steps in the campaign so it's the first place we should check for background settings in the "Container" dropdown:
Both the color, opacity, and background image can be edited here and will apply to all existing and new steps in the campaign. This is the first tier in priority when loading a campaign, this means all subsequent options will load after the theme image or color.
The column container tab
This is the second place where the background can be edited. It will lay on top of the theme background and color, and in between columns (when using split columns):
The columns
Individual columns are the top tier for images and color. These background options will lay on top of and load last over all the other options listed above which is why they're referred to as "overlay images":
These can be added to each column in the campaign and will be contained in that specific column.
