 Let's be realistic: Many developers focus on features first and don't have much time to spend polishing the User Interface (UI). We tend to be like that, too! The result is that quite often, admin apps are ugly. Spacing isn't consistent, buttons aren't in the best place, and color schemes hurt the eyes.

React-admin uses the [Material UI](https://mui.com/material-ui/getting-started/overview/) components, which are accessible by default. For its own components, react-admin uses the [WAI-ARIA](https://www.w3.org/TR/wai-aria/) standard to make them accessible. This includes `aria-` attributes, keyboard navigation, and focus management.
