Reply To: tryinh to cchange background

Hello,

I saw the screenshot you attached. If you want to add an image as the background of the HTML Block then you need to edit the Row and you add in the design tab.

If you want to ask anything else then please provide with admin panel login details to check it myself and help you out accordingly.

Best Regards.
