I'm looking to modify a few things on a specific FHEM view without having to open another port on my system. Google AI has suggested that FHEMWEB can use the attribute roomCSS to specify which style sheet loads for a given room. It has examples, and is quite convinced this feature exists. I would very much like this to exist, because it would would be a simple way to accomplish my goal.
The problem is, I can find no reference to roomCSS in any documentation, or in any source code. Google AI insists this was added in 2017, and remains in the codebase. But even searching through the SVN commits, I find nothing.
Is there something like this available? Is it maybe in a different frontend, or dashboard? Or maybe it was a removed feature?
In the end, I want to simply adjust the style of the buttons so they are larger, preferably without haveing to hand-write html to get there. I've set the uzsu style with widgetOverride for the dummy button, which helps, but they're still a bit small for my use case. Having them 2 or 3 times the size would be optimal, then I can make a few preset buttons that work well on a smaller screen.
I know the Tablet UI exists, but for many reasons I don't want to setup another port just to change to that style. I'd also like to be able to jump from that to the "normal" interface and back without having to track two separate logins. Just a room, or dashboard, or something like that with the normal UI, and slightly larger buttons, so they are easier to hit on a smaller device screen.
Thoughts? Ideas?
AFAIK there was never such an attribute.
The f18 style does have room specific colors and other options, but no room specific CSS.
You can create room-dependent styles by prepending the div[room=YourRoomName] CSS selector, at least for some of the visible elements.
