@pritikin71 classes goes after module:

right?

{ module : " calendar", classes:"foo", config: { . . . } }

css

.foo ..... { (NOT .weather) ... }

you can ALSO use the ID value assigned to the module
the selector for id is

#id ... { ... }

I use this cheatsheet to help me remember
https://www.w3schools.com/cssref/css_selectors.php

everthing before the {
is called the selector clause… because is ‘selects’ the elements of the page doc, that the stuff INSIDE the {} will be applied to

. = class # = id : is the prefix for special elements [ x ] means element with an attribute of x <div x="foo"/> nothing = tag name (table, ul, li, p, ....div)

@pritikin71 no npm/electron are not needed when u run the docker container

you just point any browser at the container exposed port

the container is running headless in server mode
