I'm trying to change the Header Height to 90px (as there is requirement to keep the header to 94px). But the header is then hiding the breadcrumb bar. Is there any way to avoid this?

.t-Header-branding {
height: 90px;
}
I have heard that the Header height should not be more 80px, Is that true? If so, where i can see the documentation regarding the same? But even with 80px it is still hiding the breadcrumb bar
