Installation

Install the theme with your preferred package manager

bun i @webtui/theme-nord
npm i @webtui/theme-nord
yarn add @webtui/theme-nord

@layer base, utils, components;

@import '@webtui/css/base.css';

/* ... */

@import '@webtui/theme-nord';

Set the data-webtui-theme attribute to the <html> tag

<html data-webtui-theme="nord"></html>

To only apply the theme to a specific element, use the same attribute

<html data-webtui-theme="dark">
    <body>
        <div data-webtui-theme="nord">
            <!-- ... -->
        </div>
    </body>
</html>
