SharePoint is a browser-based app that you connect to through your web browser, like so: Go to office.com, and sign in to your work or school account. In the upper left corner of the window, select the app launcher > All apps > SharePoint.

When you use Notepad in Windows, you can remove or change headers and footers. The default header and footer settings in Notepad are: Headers: &f. Footers: Page &p. These commands give you the title of the document on the top of the page and a page number at the bottom of a printed document.
