I’m trying to use a conditional on a style to set a background color that’s different if the user has dark mode specified in their settings. I’m getting this error: ![Screenshot 2025-06-25 at 8.13.32 AM](https://us1.discourse-cdn.com/bubble/original/3X/6/a/6a8a79b3c10e26260b4eb5e032020799c3d9a8d5.png) I would consider this a bug. Is there a work around that anyone is using? ---

UPDATE: Ugh nvm. I realize i may have misunderstood your question/issue. If so, im sorry. —— I dont know if it’s a bug. I think it’s same behavior as in web builder (since they share the same backend). I know the way i saw it implemented was by setting a state on the user’s profile if i recall correctly. It was in a video i saw. I’ll link the video once i find it. Here’s the video: [![](https://img.youtube.com/vi/kDRLpThj4Co/maxresdefault.jpg "Create Light & Dark Mode on Bubble in Under 2 Minutes! | Bubble.io Tutorials") ](https://www.youtube.com/watch?v=kDRLpThj4Co) I had a similar need, but unfortunately, that work around wasnt convenient for me. So i did change at the global style level, i changed on the element level in my page. Not ideal i know, and more configuring, but it worked for me. ---

Yeah - that video has a conditional on the appearance for body that says "Current User’s Dark Mode is “yes” … which is exactly what I’m doing basically… and what spawns that error. Weird looking error too. Feels like something is unfinished there. ---

Ah - but you CAN do a conditional based on a field that’s set to yes / no. You cannot do a conditional on a field that is tied to an option set or is data. ---
