The components are built with accessibility in mind and are designed to be easy to use and customize. 4 | 5 | ## Installation 6 | 7 | - Run the following command to install the library: 8 | 9 | ```bash 10 | pnpm install @freecodecamp/ui 11 | ``` 12 | 13 | - Import the library's base stylesheet into your app: 14 | 15 | ```tsx 16 | // app.tsx 17 | import "@freecodecamp/ui/dist/base.css"; 18 | import "./my-app.css"; // Your custom stylesheet should be imported after, in order to override the base. 19 | ``` 20 | 21 | - Use the `getThemingClass` util to get a CSS class for theming, and add the class to the `body` element: 22 | 23 | ```tsx 24 | import { getThemingClass } from "@freecodecamp/ui"; 25 | 26 | const MyApp = () => { 27 | const cls = getThemingClass(); 28 | 29 | return ; 30 | }; 31 | ``` 32 | 33 | ## Docs 34 | 35 | To see the components in action, check out the [Storybook](https://freecodecamp.github.io/ui/). 36 |
