material-components/material-components-web

Material Components for the web (MCW) is a library of ready-made UI components, buttons, text fields, menus, cards, dialogs, and so on, built by Google to follow the Material Design visual system. Material Design is Google's design language, which defines how things like colors, typography, spacing, and motion should look and behave across apps. The problem this library solves is that building consistent, accessible, and visually polished UI elements from scratch is time-consuming. MCW provides pre-built, tested components you can drop into any web project, regardless of whether you are using a JavaScript framework or just plain HTML and CSS. Each component is its own separate package, so you can install only what you need rather than loading the entire library. Components are written in TypeScript (a typed version of JavaScript) and styled with CSS. They work with a CDN link (a way to load a library directly in HTML without installing anything) or via NPM (the standard Node.js package manager for JavaScript projects). The library provides flexibility for theming, you can customize colors, typography, and shapes rather than being locked into Google's default look. Important note from the README: this project is no longer actively maintained. The team has stated they will not be prioritizing new features or bug fixes. If you are building a new project, you may want to consider newer alternatives.
