title: HTML files for different screen from asset folder
body: <p>My application contains HTML files and related images.</p>
  
  <p>I sized the images for a screen size (480x800), so that the image can fit for the screen width.</p>
  
  <p>But when My app is on large screen device, the images become smaller.</p>
  
  <p>Do I need to design HTML files for multi-screen?
  Or how to make these images fit for all screen size?</p>
