Thank you for your answer.
I enabled it and uploaded a background image. It seems that my background image is not perfectly displayed.
Please see the attachments A44.png and A55.png
and the attachments A11.png and A22.png are screenshots of my friend’s website.
On the mobile phone of my friend’s website, the header banner is displayed below the header.
How to do that? Please help me.
The header banner has a limited height. The image on the background is cut and it is the nature of images on background, we cannot change that. Try to set the color on background and insert the text.
I know how to set the header banner.
You just need to tell me how to display the header banner below the header on the phone.
