Material 设计组件和 Polymer 的 Web 组件有什么区别？
What is the difference between Material Design Components & Polymer's Web Components?
Material.io
来自 https://material.io/ 网站（官方 Google 规范？），当我按照路径访问 "Material Design UI" 网络组件时，我最终来到这里：
https://github.com/material-components/material-components-web/
聚合物项目
从https://www.polymer-project.org/网站，按照路径访问"Material Web Components":
https://github.com/material-components/material-components-web-components
我不明白这些组件集之间的区别，但想为我正在创建的网络应用程序使用 "official" Google 网络组件。
The Polymer Project is led by a team of Google Chrome developers and utilizes custom web components among other things with the goal of providing a platform for developers to build progressive web apps. Material Components for the web is an open source component library also led by Google developers and designers, but it's focus is a bit more specific to providing Material Design UI 开发人员组件。
Polymer 项目早于 Material 网络组件（和 Material Design Lite, predecessor to Material Components for the web), and Material Components for the web is part of the recommended toolkit for the next evolution of the Polymer Project。从这个意义上说，Material 网络组件在某种程度上是 Polymer 项目的一部分的继承者（但不是完全替代）。
听起来您主要是在寻找由 Google 开发人员创建的 Material 设计 UI 组件，因此 Material Web 组件可能就是您所追求的.
