title: Get screen size with Django not using JavaScript
body: <p>How do I get the current screen size and store it in session using Django? I would like to use different template code depending on screen size, whether it's a full laptop/desktop size, or mobile, etc. </p>
  
  <p>I'm trying to avoid using JavaScript to cater to mobile phones that do not have Javascript on their browsers. </p>
  
  <p>Thank you!</p>
