Putting flarum on a "wrapper" or a div

0xc00000404b

Sorry for bad English, I hope to be understood.

TL: DR: How to put/load flarum inside a div?

I have a simple website with a content div, where I alternate my pages via a jquery .load ("about.html") function, everything working fine, I made some changes to the flarum to remove the header, navigation section, etc. , I just wanted to show only the topics created

But when I load the flarum with the jquery .load ("../ flarum /") function, it loads the folder, so my localhost / mywebsite directory goes to localhost / flarum, but without changing the structure of my site, only some conflicts with css that I have already solved

I tried loading the flarum page by the index.php contained within the main flarum folder, however it is just a loader so I could understand, how can I load the flarum inside a div?

    <script>
    	$(document).ready(function(){
    		  $("#minhas").click(function(){
    		  $("#maincontent").load("aula.html");
    		  });
    	  });
