Hey KF,
there is a specialized page template in Kanso called the “Large-text page” exactly for these purposes – it will display the title of the page in larger letters, and include the content of the page as well. You can set the background for such pages in the “Page Settings” box while in the page editor mode. More information on this layout is available on pages 7 and 8 of the theme manual.
Sincerely,
Andrii / Satori Studio
