title: How to show progress bar on web page until web page is fully loaded?
body: <p>I would like to show a progress bar/loading popup in a web page until the page is fully loaded.</p>
  
  <p>My web page is heavy because it contains an HTML editor in it, which is a jQuery based HTML editor that takes a lot of time to completely load. While it is loading, I wish to show a progress bar on my page which will get removed just after my whole page has finished loading.</p>
