Question: Does mjml support body component to configure background image?

[yongma16]

I want to configure the background image in the body component of the mjml drag-and-drop editor，

Does mjml support body component to configure background image?

https://grapesjs.com/demo-mjml.html

The official website does not have a body configuration image. I want to know why it is set like this. Is it because the background image cannot be added due to email html compatibility?
