To add elements like a masthead, columns, drop caps, grab quotes, and bylines in an InDesign double page spread, you first need to import elements like the masthead from PowerPoint. You then place these elements and format text as needed - for columns you change the number of columns in a text box, for drop caps you resize the first letter, and for grab quotes you copy text to a separate text box making it larger and bold wrapping other text around it. Bylines are also placed in a separate text box above the article text at a larger font size.
