title: Is it possible to have a background image for half of the page and some contents below, and hav a navmenu that remains fixed whenever I scroll down?
body: <p><img src="https://i.stack.imgur.com/AEGUN.png" alt=""></p>
  
  <p>what I want is the top navigation block to remain fixed even when I scroll down and also have the background image to nearly top half of the page beneath the navbar(asit will be translucent and the image would be visible ) and other contents below so that it would not be on top of the  image but below the image bottom, </p>
