How to Remove the Top Banner from SharePoint Online Modern Pages?

Requirement: Remove banner from SharePoint Online Modern page.

How to Remove Banner in SharePoint Online Modern Page?
By default, creating a new modern page in SharePoint Online creates a page with large header on the top of the page. Hiding top banner from SharePoint Online pages is no longer a difficult task! Just follow these steps:

• Click on Settings gear and choose "Edit Page" to open the page in Edit Mode
  
  
• Click on "Edit" pencil icon in the "Title Area". Set the "Layout" to "Plain", save and close the page.

That's all! Please note, the plain layout is a recent update in SharePoint Online. Previously, I had to open the page in SharePoint designer and replace the line:

<mso:PageLayoutType msdt:dt="string">Article</mso:PageLayoutType>

With

<mso:PageLayoutType msdt:dt="string">Home</mso:PageLayoutType>
