Headless UI is an unstyled component library for either React.js or Vue.js from the same people that created Tailwind CSS. Our developers like that they don't have to customize or work around the default styles that other component libraries come with. The components' rich functionality and full accessibility, combined with the frictionless styling, allows developers to focus more productively on the business problem and user experience. Unsurprisingly, Headless UI also pairs well with Tailwind CSS classes.
