Hello Werner,
Thanks for writing in.
I have checked and you have a Pro license in your account but you are using the native/original header that is the default header that comes with Pro. However, since you are using Pro, you may use the built-in features like the Header and Footer builder in order to have for freedom in customizing the header and footer of your site.
You may check this link to see a tutorial on how to use the Header and Footer builder:
If you want to keep using the Original Header on your site here is what you need to do:
You have to add this code in X > Theme Options > CSS:
.x-logobar {
display: none;
}
Please go to Pro > Theme Options > Header then lessen the value that is set in the Navbar Top Height (px) option.
This should be removed when you apply the suggestion to your first question.
Please add this code in the global css as well:
.x-navbar .desktop .x-nav > li > a:hover,
.x-navbar .desktop .x-nav > .x-active > a,
.x-navbar .desktop .x-nav > .current-menu-item > a {
box-shadow: none;
}
Once you apply the suggestion for your first question, the logo bar will not be visible anymore. So to have a fixed navbar, please go to Pro > Theme Options > Header > Navbar Position then set it to Fixed Top.
Hope this helps.
