Each full page is a giant image – there are actually two images for each page: one for landscape and one for portrait mode. Yes, I’m laughing on the inside too. There is no text or HTML, just one gigantic image. The “interactive” pieces where you can slide your finger to animate it are just a series of JPG files. When you press play on the audio file and see the progress meter animate? A series of PNG files.
Something is wrong with this picture. Something wrong and something very lazy and/or desperate.
I remember like 10 years ago when the idea at a lot of small businesses was to use PDFs and Word documents to display written materials online rather than HTML. Nobody knew HTML, there were already PDFs available, why would we want to spend time making an HTML version of a sell sheet?
