Another setting I tried was: Xstore theme option > General / Layout > and adjust the site width, that will cause the width to be smaller, but 2 issues:
(1) Existing Posts are NOT changed, they stayed the same. It only show changes on “preview” when I have the Xstore toolbar open on the left.
(2) I just want the paragraph section to be “narrower”, but this method will add space to the title as well.
