I am starting with my programming skills. I m self learning so I am stuck in this point I am trying to create a web map where charge few different layers (wms) but I would like to give functionality to them providing control with the opacity so you can overlay two layers at same time, but I have no idea how to do it. I tried few ideas I read from here but I am not sure what I am doing wrong.
