Material UI is an open-source React component library that implements Google's Material Design. It's comprehensive and can be used in production out of the box.

/**
 * NoSsr purposely removes components from the subject of Server Side Rendering (SSR).
 *
 * This component can be useful in a variety of situations:
 *
 * * Escape hatch for broken dependencies not supporting SSR.
 * * Improve the time-to-first paint on the client by only rendering above the fold.
 * * Reduce the rendering time on the server.
 * * Under too heavy server load, you can turn on service degradation.
 *
 * Demos:
 *
 * - [No SSR](https://mui.com/material-ui/react-no-ssr/)
 *
 * API:
 *
 * - [NoSsr API](https://mui.com/material-ui/api/no-ssr/)
