Hello (sorry for my bad english).
I have searched but not found what I want. I would like to know if there is a possibility to incorporate an option for each page. Something like in the Customize. Each page has a different wallpaper and I want to modify the opacity of each wallpaper with an option in the Page.
I don’t know if I’m clear, but with the customizer I change the option for all the pages. What I want is to have an option for each page and a different variable and modify ti in the page and not in the theme customizer. The same way I change the Page attribute or the author.
Thanks you very much for your help and have a good day !
