<!-- The spec offsets the center of the ImageView from the center of the screen by either 16 or
     24dp, depending on the device type.  That's implemented here by adding a bottom margin of twice
     that amount to the RelativeLayout, which effectively moves its center upward by the desired dp.

     Because the title of the web app sits at a fixed distance from the bottom of the screen (either
     48 or 56dp, depending on the device), the RelativeLayout's padding is subtracted from it to get
     the correct spacing. -->
