With Modern Visual Defaults (Fluent 2), many things we used to fix with JSON are now part of the standard experience: cleaner visuals, consistent spacing, subtitles, rounded corners, and built‑in style presets per visual. In this demo‑driven session, we take a fresh look at Power BI theming, starting from Microsoft’s updated base theme, and then moving beyond it where customization is still needed. We’ll move up and down the theming stack: ✔️ Explore the new default base theme and modern visual defaults to understand what Power BI now gives you out of the box ✔️ Look at style presets, how they affect visuals, and how you can adjust or override them ✔️ Customize the theme via View > Customize current theme to see how structural settings flow through the report ✔️ Export the theme and fine‑tune it in JSON for advanced or unsupported properties ✔️ Clean up and adapt older themes to work with the new defaults instead of against them The session fully incorporates the Modern Visual Defaults & theme improvements preview, showing how Microsoft’s new direction changes the way we should approach theming and report design. This session is aimed at experienced report builders who want consistent, scalable design without repetitive formatting. Everything is shown live in Power BI, no slides, with a downloadable theme file to take home and adapt. | |
