I've put together a quick demo of a menu idea for a mobile website or app. It only took me 20 minutes to build the entire prototype. Feel free to import and dissect.
An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation.
This prototype is designed to be a promotional website for the Alps and features animations based on the scroll position. Thanks to https://dribbble.com/victorerixon for the inspiration.
