You can do this with a CSS-based approach, using an IF THEN ELSE or SWITCH in Glide to control the theme.

I discussed the concept of switching Glide’s Light and Dark environments dynamically here:

> This CSS trick successfully switches between Dark and Light environments inside Glide — tested directly in the DOM (not in the custom CSS field). I’m not sharing the full code here since it’s quite long, but the concept is fully replicable. [ScreenRecording2025-09-30131621-ezgif.com-video-to-gif-converter] How it works: Set your app’s base appearance to either Dark or Light under Settings → Appearance. Create a flag column in your User Profile table that stores which button (Dark/Light) …

The post documents the **concept and approach rather than the full CSS code**. The original implementation was quite extensive because it required overriding multiple parts of Glide’s UI.

For your particular use case, I would actually consider using **dynamic theme colors** rather than trying to reproduce the entire Light/Dark environment. It is much simpler to manage and can still be driven by a Glide condition or SWITCH.

Here is another example where I used `:has()` to respond to app state and dynamically change theme colors:

> Here’s a simple dynamic CSS trick to make your Glide app’s theme automatically change based on user roles — like admin, member, vip or banned. By declaring global CSS variables and using the :is() selector to shorten rules — together with :has() for data-driven conditions — you can keep your CSS clean, dynamic, and highly scalable.

So the general pattern is:

**Glide condition / SWITCH → expose the state in the DOM → CSS responds to that state → theme changes dynamically.**

This can be adapted for a development toggle controlled from within the app, without changing the setting in the Glide builder.
