I just found that Google has added Gemini to DevTools. I usually right click on an element on a dashboard and press inspect to bring up DevTools, to find the Ids of the elements I want to modify, but I just noticed an AI option while I was there, so I added it.
With a prompt including that the current page is a Hubitat Dashboard, and that you want to modify the dashboard css file for a specific tile ID and its child elements, it looks like it could be useful if you get specific about child elements based on div IDs inspect brings you to.
