Use CSS-in-JavaScript with themes for React without being tightly coupled to one implementation
Role in this project:Front-end Developer
Front-end DeveloperContributions:33 commits, 23 PRs, 33 pushes in 7 months
Contributions summary:Maja primarily contributed to the development and improvement of the `react-with-styles` library, focusing on features related to Right-to-Left (RTL) language support and stylesheet management. Their work involved modifying the core components to handle directional contexts and dynamically create stylesheets based on the direction, ensuring proper rendering in RTL environments. The user also refactored the library's internal structure by moving the stylesheet creation to the `componentWillMount` method and passing the `css` method down as a prop.
