Thank you Strawberry!
I will give it a go :)

Sorry if i put this post in the wrong category.

I have just started to fine-polish the last pieces in the config on my MagicMirror when my better half comes screaming " I want an whiteboard!"
Then the idea came to me that instead of making a mirror, i just use a ordinary glas and use it as an whiteboard. But i dont want it to have a white background all the time…

So my question is, is it doable by an physical button/switch to “invert” the colors on the hole layot ?

So that the handwritted “Whiteboard-text” is almost hidden when in “MagicMirror-Mode” (Original layot) and with the press of a button or switch the hole layout is inverting, making the background white and text black.

I have NO prior knowledge of programming, but i am not afraid to try. But i might need a push in the right direction first :P

My first idea involved a script like this:

´Push button´
Making it activate a script that replaces ´/css/main.css´ with ´/css/main2.css´ and thereafter sends a ´refresh´command.
Sort of…
( This is my programing abilities ;) )

Am i reaching for the stars here or is it something that is doable? Maybe there is another solution?
