Next to the navigation you can add a call to action buttons that can be linked to any page internal or external. In our theme demo we use it to link the buttons to the appointment and quote page:

The button can be edited under Appearance → Cusomtize → Header → Buttons

You can also use this button as phone number link by adding the following to the “Button link” settings:

tel:123456789

Remember to remove all spaces and symbols from your number

Or add your email to the link setting:

mailto:info@yourdomain.com
