Hello,
If you just want to remove the background color only then you just can add the following CSS to the Additional CSS section in your customizer.
#custom-header::after {
background: #fff;
}
#custom-header {
padding: 30px 0;
}
.custom-header-wrapper .page-title {
color: #000;
}
#breadcrumb li {
color: #000;
}
#breadcrumb li a:hover {
color: #000;
}
If you just want to hide all that section along with the title and breadcrumbs you can use the following CSS
#custom-header {
display: none;
}
Hope this solves your problem, if you still get confused please let us know we will be happy to assist you.
