YouTube is launching a redesign of its desktop site, which now takes advantage of Google’s design language, Material Design, to make the site cleaner, simpler and more consistent with the YouTube app across devices. The site will also include a handful of new features, including a new dark mode, tweaks to search and channel pages, and an updated theatre mode for watching videos in a larger player without going full-screen. The site has been rebuilt on top of Polymer, the open source JavaScript library introduced at the Google I/O developer event several years ago. The benefit to using Polymer is that it allows developers to create web components that can be re-used.
