Text within an Excerpt macro is displayed as smaller than the text on the rest of the page. This is the case both in the editor and when viewing a published page. There is no way to manually set font size for "normal text" which makes it impossible to fix this issue.
Confluence Cloud + New (fabric) editor
- Create a page and add text
- Add an Excerpt macro and fill with additional text
- Publish and observe the difference in font size
The text within the Excerpt macro is displayed with the same font size as the rest of the page text.
There are no workaround available at the moment.
