The header, the footer and the sections around them live in a layout, not in each template. A layout wraps every template that uses it, so a change to it shows on every page at once. Every project starts with one layout, Default, which all templates use.
Open the layout
Open your project in Fantasma.
In the icon rail, click the second icon, Layouts. The Layouts list opens with Default.
Click Default. The layout opens on the canvas, and its sections are listed under Sections: Navigation, the header, then Template Sections, Newsletter, a signup band, and Footer.
Template Sections stands for each page's own content. On the canvas it is an empty band with the line "Sections you add to the template appear here." Sections above it show above every page's content, and sections below it show below.
Change the header or footer
Under Sections, click Navigation for the header, or Footer for the footer. Its settings open in the right sidebar.
Change the settings, or click a block inside it on the canvas to edit it, like any other section.
Click + next to Sections to add a section, such as a banner with a short notice.
In the Sections list, drag a section above or below Template Sections to show it above or below every page's content.
Right-click a section in the list or on the canvas, and select Delete to remove it.
Template Sections stays in every layout and cannot be removed.
Edit the header from a template
When a template is open, such as Homepage under Templates, and you select its header or footer, the right sidebar says "This section belongs to Default layout, so changes here affect every template using that layout." You can change its settings and text there. To add, move or remove its blocks, click Change in layout editor, which opens the layout.
The panels under Overlays, below the layout's sections, belong to the layout as well, such as the Mobile menu that opens on phones. The layout's Used by list in the right sidebar shows every template that uses it. Your Ghost site gets the changes when you publish your theme or upload it again. To use another header on some pages only, see Use a different header or footer on some pages.

Change the header or footer
The header's menu links come from Ghost, as Set up your site menu explains. The header's own settings, such as Sticky, are in Navigation section.
The copyright line of the Default footer starts with "© {currentYear} {siteTitle}". Ghost fills in the current year and the site title from Ghost Admin, so both stay current by themselves. The canvas shows the demo site's title until you preview with your own site. The footer's menu links are your Ghost secondary navigation, which you edit in Ghost Admin.
Add, move or remove a layout section
