Hello Octatech,
Thank you for contacting us and for using XStore.
Try to use the next custom CSS code:
.header-main .et-row-container { background-color: black; border-radius: 0px 0px 10px 10px; box-shadow: 0px 1px 10px 5px #222; }
The content of the Header can be changed via Header Builder. We hope this information is helpful.
Kind Regards, 8theme team
