How to organize the development of a website using github?

Question

git

There are 2 domains - mysite.info and mysite.biz. On biz I constantly throw in the layout, on info we pull it. How can I implement permanent work with projects through github so that there are no problems with versions for each of the users (backend is usually wp or laravel)

Answer 1

About 2 years ago I practiced the following:
In the repository I had 2 branches: master and html.
master - WP
html - layout
In the master branch, I set up a submodule from the html branch to the theme folder, it looks like this take.ms/LpfHC
When pooling from master, the submodule is also updated (pulls all changes from the html branch)
Here is my bash script - take.ms/ rb8xC
