The React UI library you always wanted MUI provides a robust, customizable, and accessible library of foundational and advanced components, enabling you to build your own design system and develop React applications faster. MUI components work in isolation. They are self-supporting, and will only inject the styles they need to display. They don't rely on any global style-sheets such as normalize.css. You can use any of the components as demonstrated in the documentation. Please refer to each component's demo page to see how they should be imported.
