To centre your logo so it splits your navigation menu in half, you need to change to a template that supports this feature. An example of this is the “Vista” template with the feature area text “Scenic Helicopter Tours”. Learn how to change templates
Once your template is changed to a split menu template, you can click Change Design.
Then click Logo & Menu to adjust the spacing on either side of the logo. Click and drag the arrows on either side of the logo to adjust the spacing.
