Hyvä UI utilizes CSS variables to define core design themes, while Tailwind tokens provide the building blocks for styling individual components within those themes. This creates a flexible and efficient system for building UIs with Hyvä Themes.

Hyvä UI leverages CSS variables and Tailwind tokens to achieve several key benefits:

1. Centralized Control: Hyvä UI defines core design elements like colors, fonts, and spacing using CSS variables. These variables are stored in a central location within the Hyvä Theme project.

2. Theme Customization: Developers can easily customize the overall look and feel of the store by modifying the values of these CSS variables. This allows for creating a branded and unique user interface without modifying the core Hyvä UI component code.

3. Component Reusability: By using CSS variables, the same Hyvä UI component can adapt to different themes simply by changing the variable values. This promotes component reusability across various store designs.

4. Rapid Prototyping and Styling: Hyvä UI utilizes Tailwind CSS classes (often referred to as tokens) for styling components. These tokens provide pre-defined utility classes for things like margins, paddings, colors, and typography. This allows for rapid prototyping and efficient styling of UI elements.

5. Responsive Design: Tailwind tokens often include responsive variants, allowing for easy control of styles across different screen sizes. This simplifies the process of creating responsive UIs for your Magento 2 store.

6. Consistency and Maintainability: Using Tailwind tokens promotes consistency in styling across Hyvä UI components. This makes the code easier to maintain and understand for developers working on the project.

Here’s an example:

A Hyvä UI component might use a Tailwind token like text-red-500 to set the text color to red. However, the actual red color shade might be defined by a CSS variable –brand-red within the theme. This way, you can easily change the overall “red” color used throughout the store by modifying the –brand-red variable and all components using the text-red-500 token will automatically reflect the change.

In short, Hyvä UI’s combination of CSS variables and Tailwind tokens offers a powerful and efficient approach for creating and customizing user interfaces for Magento 2 stores using Hyvä Themes. It promotes theming flexibility, rapid development, responsive design, and maintainable code.
