Applying the Ion theme to a document primarily changes what?

• A. Fonts, colors, and effects across the document
• B. Page margins only
• C. Line spacing only
• D. Header height only

Answer: (A)

Applying the Ion theme establishes a unified look by choosing the font set for headings and body text, the color palette used for text and objects, and the set of effects that apply to visuals and borders. This bundle updates formatting across the entire document, so you get consistent typography, color, and stylistic accents from start to finish. It doesn't change margins, line spacing, or header height by itself; those are layout and paragraph settings you adjust separately. You can still tweak them after applying the theme, but the theme's primary role is to standardize fonts, colors, and effects across the document.
