I have made a custom content block inside Content Builder using the Block SDK and I need to figure out the width of the space inside of the email (when editing) so I can set the width of the images created while using my custom block.
For example, if there is a 2 column layout in the email and each column is 300px, I need that data passed through so I can set image widths to 300px.
Here is the documentations: https://github.com/salesforce-marketingcloud/blocksdk
I've tried getData()
ect to no avail.
