How to properly use 2 git repositories in one project?

Question

git

There are 2 projects with the same codebase but different HTML templates.
I can't figure out how to properly use 2 git repos to store the codebase and templates separately.
Let's say the project structure is
/www/ <- 1 repo
/www/templates/ <-2 repo (I want)
there is a solution that seems ugly to me
/www/ 1 <- repo
/templates/ 2 <- repo
/www/templates/ -> /templates/ Symlink
But I want something simpler or something :)
Or maybe there is a completely different solution for such a task?

Answer 2

Add a folder to ignore for the first repository, and do anything inside, even the second repository
