The document summarizes 2013 web design trends, including responsive web design, flat design, parallax, large photo backgrounds, and infinite scrolling. Responsive web design adapts the layout to different screen sizes and devices. Flat design uses simple elements, typography, and color without gradients or shadows. Parallax creates a sense of depth by scrolling through layers of images at different speeds. Large photo backgrounds place images behind page content. Infinite scrolling continuously loads new content as the user scrolls down the page without pagination.
