Hi ... I've been wanting to use css variables in my custom char sheet CSS file. specifically I want to put my URL's for my various logos and backgrounds into variables at the top of the CSS file so while I testing with different looks I don't need to change all locations, just change the vars at the top of the CSS file. I figured out that the scope for all variables in the sheet you can put them into the . charsheet style ... .charsheet { --charsheet_background: url("your path here"); --charsheet_hdr_background: url("your path here"); --titles_background: url("your path here"); } And then reference them throughout the rest of the CSS classes. For examples, for images I use in multiple places now I can just do this ... background-image: var(--titles_background); If I want to change the background of my titles I just change the one var at top. I also want to use variables for my rolltemplates css classes, however they don't seem to play like the classes in the charsheet (no surprise). :root does not work. I have numerous rolltemplates in my HTML, and such have numerous corresponding classes in my css, but I cannot determine how to scope the variables so they work across all rolltemplate classes in the css. Anyone have a suggestion? Cheers!
