Website code got changes

Are you asking where this content should go inside your documents?

<script type="application/ld+json">

Schema is just read by search engines to help generate rich snippets that can be viewed in search results of some search engines.  Based on what you have currently with the json+ld code, the placement of that type of code is fine because it's not intended to be inline.  If you run your page through the rich results test you will see what google can see for instance ( https://search.google.com/test/rich-results ).

Does this help, or is there something in particular you are having difficulty with?
