How to Customize the Header & Footer in WordPress Full Site Editor

How to Customize or Replace the Header

To customize your header, you’ll edit the Header template part. By editing this template part once, the changes will take effect on all pages of your site. Follow these steps to access the Header template:

In your site’s dashboard, go to Appearance → Editor.
You can edit the header from multiple locations: Site, Templates, or Template Parts. It all depends if you want to make changes on all pages or only on specific ones.
For example, you can click on the Site section in the Site Editor.

Everything in the header is fully editable using blocks, and you can remove any unnecessary elements and add new ones, like Social Icons, Buttons, Search Form, and Logo Image.

Adding template parts to a template via the Site Editor or Template Editor

In order to add a Template Part block to a template via the Site Editor or Template Editor, click on the Add block button and select the Template Part block. You can also type / template part and hit Enter in a new paragraph block to add one quickly.
