How to wrap sections in a new page?

[Elka]

Hello everyone 😊

Please can anyone tell me how to wrap section.json with a div tag on for a page?

for example, I have 2 different pages besides the homepage, Page-A (page.a.json), and Page-B (page.b.json), what I want to do is to wrap a div with a different class of each page but I don't want to touch the HTML on the homepage (theme.liquid)?
