Hey sorry for the long delay. You are correct i indeed forgot to mention that you should import the .less module somewhere in your entry point so i’m gonna fix that.
With regards to not seeing any of the changes, can you first validate that you have the proper folder structure and then can you see (with a simple ctrl+F) whether your custom changes are included in the webpack bundle (supposing you have imported the .less library as you pointed out in your comment)? If webpack doesn’t bundle then it’s probably a broken configuration; if it does bundle then it’s most likely an incorrect folder structure.
I have verified this process in 3 different projects, but i’d be keen in figuring out what the problem is :)
