# About Base UI Solid

An overview of Base UI Solid, the unofficial Solid port of Base UI, and how it relates to upstream.

Base UI Solid is an unofficial port of [Base UI](https://base-ui.com) to Solid 2.0.
Base UI is an unstyled React component library for building accessible user interfaces, created by the team behind Radix, Material UI, and Floating UI.
This port is not affiliated with or endorsed by the Base UI team.

The port follows upstream file by file: components keep the same parts, props, data attributes, CSS variables, and behavior, and the upstream test suite is ported alongside them.
Where React and Solid differ, the port adapts the API to Solid (for example `class` instead of `className`, and reactive accessors instead of hooks).

## Features

### Headless

Base UI components are unstyled, don't bundle CSS, and don't prescribe a styling solution.
You retain complete control over your application's CSS layer.
Base UI is compatible with Tailwind, CSS Modules, plain CSS, CSS-in-JS, or any other styling engine you prefer.

### Accessible

Poor accessibility can make your application difficult to navigate for all users, not just for users with disabilities.
Accessibility is our primary focus.
Base UI components adhere to [WAI-ARIA design patterns](https://www.w3.org/WAI/ARIA/apg/patterns/) and are tested on a wide range of platforms, devices, browsers, screen readers, and other environments.

### Composable

Component APIs are fully open, so you have direct access to each node, you can easily add or remove parts, and you can wrap them however you prefer.

## Credits

The component design, behavior, accessibility work, documentation, and demos come from the upstream [Base UI](https://github.com/mui/base-ui) project and [its team](https://base-ui.com/react/overview/about#team).
Base UI is licensed under the MIT license.

## Browser support

Base UI supports all modern browsers that implement features marked as [Baseline Widely Available](https://web.dev/baseline) at the time of the last major version release.
This means the features we use have been supported across major browsers for at least 30 months, ensuring broad compatibility and stability.

For the full list of supported browsers, refer to our <a href="https://github.com/ZerNico/base-ui-solid/blob/main/.browserslistrc">.browserslistrc</a>.

## Solid versions

Base UI Solid targets Solid 2.0 RC. It does not support Solid 1.x.

## Bundler support

Base UI works with maintained versions of all popular bundlers, including Vite, webpack, Turbopack and Parcel.
