Lesson Notes
Read through the key concepts before you try the challenge.
A coordinated redesign in one click
You are preparing a report for the board at Lakeside Medical Associates.
The content is finished but the document looks like a first draft. You could adjust each style by hand, or you could apply a style set and see the whole document restyled coherently in one click — then fine-tune from there.
Your task: Use style sets to reach a professional baseline quickly, instead of designing every style from scratch.
A style set is a coordinated collection of definitions for the built-in styles — Heading 1 through 3, Normal, Quote, and the rest — designed to look right together. Applying one from Design > Document Formatting changes fonts, sizes, and spacing across the whole document simultaneously.
Style sets only reach text that uses styles. This is where the value of the previous lessons becomes concrete: a document built with real Heading and Normal styles transforms completely, while a document formatted by hand barely changes, because none of its formatting is connected to a style definition.
What Is a Style Set?
A Style Set is a coordinated collection of heading, body, and paragraph style definitions. Switching Style Sets changes the fonts, sizes, and spacing used by all built-in styles at once — without removing the styles themselves.
Accessing Style Sets
Go to the Design tab and look at the Document Formatting group. The row of thumbnails at the top represents the available Style Sets. Hover over any thumbnail to preview the effect on your document.


Applying a Style Set
Click a Style Set thumbnail to apply it. Word updates all heading and body styles throughout the document to match the new set.

Restoring to the Default Style Set
To return to Word's original default styles, click the first thumbnail (Default) or right-click the Style Set gallery and choose Reset to the Default Style Set.

Saving a Custom Style Set
After customizing styles, you can save them as a new Style Set. Click the More arrow in the Document Formatting group to expand the gallery, then choose Save as a New Style Set. Name it and click Save.
