Hi @Jeon,
Thank you so much for your kind words of appreciation! We are glad our theme worked out for you.
Regarding the issue with the display of header image in mobile screen size, the difference in the screen real estate between a desktop and a mobile is huge, thus, to fit an image for a mobile view would require displaying only a part of the image in order to handle the resizing of the section ie, downsizing of background image and increasing of the header text. The rest of the image would not be displayed and only a particular section of the image would be focused in.
An image that doesn’t require the site to display the image in full such as a patterned background might be more suitable here.
Hope this would resolve your query.
Thank you
Regards,
