This is a web banner I made for the Naturmuseum St. Gallen, using Google Web Designer and only components of the official poster. The background color was already defined, too, just as the three different formats for the web banners.  I used the same components I prepared on photoshop for all three banners without changing them. There is a «leaderboard» (728*90px), a «rectangle» (300*250px) and a «skyscraper» (160*600px).
