I am using the cupper theme with some modifications. I installed the original theme as a submodule and saved the data in root/themes/cupper-hugo-theme; the customized one is applied in a way of overriding, that is, I copied the original structure of cupper-hugo-theme into the root directory and modified them.
Now, I am about to install and move to another theme. Ultimately, I want to save both themes and want to be able to switch within them using the theme variable in the config.yaml.
Before adding another theme, I want to save the current theme (modified cupper). I conceive that I can do it by the following steps:
pack the current theme in a new folder (i.e. cupper-hugo-theme-modified)
save the cupper-hugo-theme-modified folder in root/themes folder
install a new theme in the root/themes folder
copy the structure of the newly installed theme into the root directory and customize it
, but I cannot try it, wondering it may provoke irreversible errors (sorry for not providing any codes in this query).
