    Styled Components

    Styled Components

    Visual primitives for the component age

    Visual primitives for the component age. Use the best bits of ES6 and CSS to style your apps without stress. Utilising tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allows you to write actual CSS code to style your components. It also removes the mapping between components and styles, using components as a low-level styling construct could not be easier! Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries. styled-components is compatible with both React (for web) and React Native, meaning it's the perfect choice even for truly universal apps! ...

JSON Forms utilizes the capabilities of JSON and JSON schema and provides a simple and declarative way of describing forms. ...
