Google Chrome extension - stop loading website after loading a single div

Question

manifest.json

"content_scripts": [ 
   {
      "matches": ["https://somepage.com"],
      "js": ["content.js"],
      "run_at": "document_start"
   } 
],

content.js

setTimeout(function(){ 
    window.stop();
}, 10);

I have this, but it's bad, because somebody who have faster connection it will won't work for him. We have some page, with three divs: logo, page-content, footer, and I want to interrupt loading website when the page-content is already loaded and it will load only two divs: logo and page-content.
