Thank you.


Hello there,

Adding social profiles above the menu hasn’t been supported yet by the core code. Read this documentation to add header contact address (Pro version is required).

To reduce your site header, you would need to add this CSS code to Appearance > Customize > Additional CSS in your site dashboard. Do adjustment if needed.

.site-header.float-header {
   padding: 5px 0 !important;
