The first thing you see when you enter a website is usually the color scheme and the body of the webpage. To me, the color scheme and design components ( more on that in a moment ) are the most important elements of a webpage. For the design cmponents, I mean what the buttons, header, and in general how everything behaves. My favorite design component is called Material Design. Material design was introduced by google and android 5.0 and 6.0 is the showcase for the design language. It looks really good to me, and it favors responsiveness and really cool animations. This implemented right looks amazing on a webpage.
