What is the difference between a stretch on a CMS and just “make a website on a constructor”?

Question

CMS

In my understanding:
- if on the constructor, then you will be without a source code and less opportunities for design and functionality;
- and the stretch is good, please explain.

Answer 1

In polite society, the "stretch" is called Design / Layout Integration .
The documentation of the required CMS opens and in the design integration section there will be everything about the template engine.

Answer 2

This is called customization, learn this word and your price tag will increase by 2-3 times. However, the above said correctly, the key word is the creation of topics. Formally, all CMS support this from stupid templates to entire guides for customizing each part of the application.
