title: Why browser sometimes render site bad and sometimes good? (without change browser, no dynamic data only refresh)
body: <p>I have website, usually all looks fine but sometimes one div is on the wrong place... For now, I thought reason is AJAX (when <code>document.ready</code> load welcome text), but now that script is disabled and problem still exist. <br><br>
  For now, I have noticed that only on latest Firefox. Anyone else had similar problem? Is it fault of free hosting (and maybe some packet is lost...?) (tested on <a href="http://60free.ovh.org" rel="nofollow noreferrer">http://60free.ovh.org</a> and <a href="http://www.000webhost.com/" rel="nofollow noreferrer">http://www.000webhost.com/</a>)</p>
  
  <p>EDIT:
  I am talking about only ONE browsers and 2 diffrent results of rendering. I know it is very strange... </p>
  
  <p>EDIT2:
  Look at this screenshot:
