Dear Sajid,
We are sorry to say that your request does not cover item support. Because it’s all about customization based on your specific needs and requirements.
However, we can provide you a hint to do the customization even it does not cover item support. You can add the section id with our provided custom CSS that section background you want to make white.
Example:
#services, #domainSearch {
background: #fff;
}
Best Regards,
ThemeLooks Support Team
