Hello,
1. Try to use this code in style.css of your child theme:
.navbar {
padding: 0px !important;
}
Also the reason of large space is your logo size. It’s big. Try to decrease it.
If you use child theme you need make changes in style.css of the child theme and not in custom.css file.
2. Use this code in style.css of the child theme:
.fixed-header-area .header-logo img {
width: 200px !important;
}
3. Add this code in style.css:
.content-page {
margin-bottom: 0px !important;
}
Regards,
Eva Kemp.
