Header
Header replaces SharePoint's rigid grey site header with a fully branded one - your logo, colours, fonts, navigation style and background. It has two parts:
- a Header Designer web part - the control panel where you design and save the header;
- a Header Customiser extension - applies the saved header site-wide automatically once deployed.
Permissions
Header needs no Microsoft Graph permissions. It uses SharePoint's own APIs as the signed-in user.
Set up
- Install the package (see the Install guide).
- On any page, edit → add the Header Designer web part to open the control panel. You can keep it on a hidden admin page; the header itself renders everywhere regardless.
- Design your header, then click Apply. The saved configuration is rendered site-wide by the extension.
What you can configure
- Layout - height, alignment, and how the logo, title and navigation sit together.
- Navigation - several nav styles (underline, pills, hub-nav end-cap and more), with your own links.
- Colours - background, text and accent colours, computed for accessible contrast.
- Background - solid, gradient or image.
- Logo & fonts - upload a logo and choose typography.
Apply, reset, import/export
- Apply publishes the current design site-wide; Reset reverts to the SharePoint default.
- Export / Import lets you save a header design to a file and reuse it on another site or tenant.
Changes appear after you click Apply and reload. If you don't see the header, confirm the package is deployed "to all sites" and your tenant is activated.
