title: Loading screen in an HTML5 app
body: <p>I'm working on a project (not a game) that involves getting a number of big assets (css, js, etc). When opening the page in an UIWebView (iOS) there is an empty white page for 3-5 seconds while everything gets loaded.</p>
  
  <p>I'd like to avoid that. I'm guessing I should add an HTML5 loading screen but I have no idea how to do that. Any pointers?</p>
