And Google for requests on how to make a template for opencart yourself or YouTube, at least look at these videos there.
The method that I use: I put the necessary CMS, put any ready-made template and see how it works, what files it is divided into, where are the calls and what they are responsible for. Then I break my layout accordingly and insert the code responsible for calling the necessary blocks, menus, news, etc.
