Change current CSS with a module?

[MacG]

@sdetweil The ID is well known because I have already changed or tried some things with the custom.css. It’s “module_1_MMM-BackgroundSlideshow”.

@macg be careful… if you change the order in config.js, then the identifier will change…

@sdetweil I know. Fortunately, from my logical point of view, the background is with one of the first modules.

After your post from Friday, I had the idea to create maybe two instances of the MMM-BackgroundSlideshow. One with and one without gradient. With the MMM-Remote-Control, I could then set active the instance which is needed. So that the dashboard is readable and the gallery mode is without gray haze. That would save me the module programming. Is everything new for me anyway.

This doesn’t work. Also not with the second instance as “fullscreen_above”. So back to plan A again.

I don’t have the knowledge for plan A. I tried it, but it doesn’t affect the display and it doesn’t show up on MMM-RemoteControl in the Edit View list. What is necessary though.

I can change or add a few lines of code, but I can’t rewrite a module. The gradient stays as it is.

/*

to disable the following class

.MMM-BackgroundSlideshow .gradient background-image: radial-gradient(at center top, rgba(0, 0, 0, 0) 45%, rgba(0, 0, 0, 0.45) 85%) !important;

 */


Module.register("MMM-BGSs-NoGradient", {
	// define variables used by module, but not in config data
	// some_variable:  true,
	// some_other_variable: "a string",

	// holder for config info from module_name.js
	config:null,

	init: function(){
		Log.log(this.name + " is in init!");
	},

	start: function(){
		Log.log(this.name + " is starting!");
	},

	loaded: function(callback) {
		Log.log(this.name + " is loaded!");
		callback();
	},


	// return list of stylesheet files to use if any
	getStyles: function() {
		return 	[

			//'script.css', // will try to load it from the vendor folder, otherwise it will load is from the module folder.
			//'font-awesome.css', // this file is available in the vendor folder, so it doesn't need to be avialable in the module folder.

	},


	// messages received from other modules and the system (NOT from your node helper)
