Hey Nanette,
I think I know the cause: the italic descriptions in the Kanso demo are sourced from excerpts, which can be inputted in a special box below the main content editor in the page edit mode (in case the excerpts box is not displayed, click on the „Screen Options“ tab in the top right corner of the screen, and tick the „Excerpt“ checkbox). They will align as needed automatically ;)
Sincerely,
Andrii / Satori Studio
