This is a blank web design.
We have just added a Title and a menu to get you started.
If you do not need them you can just delete them.

The Title and Menu are set as Globals so they will display in all the pages of this site.
You can turn any element as Globals, click on it, in the left tab click on Properties then check the box Global.

If you want to create web site designs for PageBuilder, install the Design Builder package. (go in Settings -> Manage Add-on -> Install the design builder Add-On tool).
So you can package then install them on your customer or friends web sites.
