title: Image and CSS pre loading in Django
body: <p>I am developping a website with Django, hosted on Heroku, and still fairly new to it.</p>
  <p>I published my application, and notice a problem when navigating on the hosted website :</p>
  <p>Whenever you load a new page, it looks like images and css are reloading completely. For a short time (less than 1 second), It creates some king of glith on my menu bar because buttons are moving (because the image is missing) and changing color (because css is missing).</p>
  <p>What would be a proper way to handle this ? Is it possible to store those image and css in somme kind of cookie on the user browser ?</p>
  <p>Also, when i run the website on my localhost, i don't experiment the problem.</p>
  <p>Thanks for your help !!</p>
