How to organize several pages with a unique design on joomla 3?

Question

Joomla

Good day!
The third day I am tormented by the question of how to correctly implement such a moment. There is a site on joomla 3. It has a main page with its own design, and there is a subsection (for example, AUTO). In the menu there is such an item - AUTO. So, when you go to this item, we get to a simple page with 6 previews, but when you click on a preview of a particular car, we get to a page with a unique design.
Here's how to make this "page with a unique design" ..? (There should be 6 such pages - according to the number of previews). Styles - must be in accordance with the styles of the site, only the location of blocks, texts and information in general - will be different.
Ps What confuses me - in fact, it turns out the usual material (if you follow the logic of joomla) If I do not confuse anything. And here's how to make your own formatting, your own unique design for a separate material ...
The menu and footer are the same as on the entire site, only the content is different.
Can someone tell me where I'm stupid and give a kick in the right direction ..? I will be very grateful.

Answer 1

Well, set the menu item to your template style (pre-written)
