Modifiers and Looks are two new contrib modules which open up new creative possibilities to editors and designers. When used together they combine to provide a powerful, reusable system enabling modifications to be made to individual entities as well as site wide components. Typical modifiers include typography, color, background images, parallax, video, corners, shadows and many others. It is possible to define collections of modifiers as Looks in the UI and then apply them to different parts of the site as required. This makes it possible to build and design Druapl 8 sites without touching the theme layer at all.
