My logo size is a max height of 60px so had to add some custom CSS to adjust the header height to 70px:
Logo Size:
.Header-logo {
position: absolute;
max-height: 60px;
vertical-align: middle;
margin:-10px;
top: 15px;
}
Increase Header Height:
.App::before {
height: 70px;
vertical-align: middle;
}
#admin-navigation {
top: 70px;
}
Lower notifications and search items on the header so they align in middle vertically:
.App-header .Search-input {
padding-top: 10px;
}
.Header-navigation {
margin-top: 10px;
}
