I'm trying to determine what graphics styles and design features are being used on some recent websites. I am not a UI developer but work with many front ends and I'm not sure how to describe certain features such as the graphics and icons to others. So this may be more of a style question. I'm all set with understanding and identifying the underlying technologies involved through sites such as builtwith, etc. I've listed some examples of sites that have the styles that I'm curious about where each site has a common graphic style.
The two sites you've linked to use a flat design (very in at the moment) and are use the 'one page' idea - that is on long scrolling page. One has a sticky header navigation.
The answer is mostly related to visual style. The idea of long scrolling pages is more of a UX idea and ties into the concept that people prefer to scroll down a page than to click and jump or click and expose items.
If that doesn't provide you what you need then you might need to be more explicit.
