> [!info] Quick Definition
> **Variables** are raw and dynamic values (numbers, colors, strings, booleans) that allow for creating themed systems and advanced prototypes. **Styles** are collections of visual properties (such as gradients, effects, or complex typography) that define an element's final appearance.


## The Dilemma: Variables or Styles?

Figma has evolved toward a much more powerful model with the introduction of Variables, but Styles remain fundamental in many workflows. Understanding the purpose and limitations of each of these elements will help you build a more robust and easy-to-use design library.

## Main Technical Comparison

| Feature | Variables | Styles |
| :--- | :--- | :--- |
| **Color Support** | Solid colors only. | Solids, complex gradients, and images. |
| **Typography** | In progress (currently very limited support). | Full support for families, weights, and sizes. |
| **Modes (Light/Dark)** | Yes (supports multiple swappable modes). | No (requires manually duplicating color styles). |
| **Logic / Prototyping** | Yes (can change value dynamically). | No (they are static). |
| **Data Types** | Color, Number, String, Boolean. | Effects (Blur, Shadow), Grid, Text, Color. |

## When to Choose Each

### You should use Variables when:
- **You need Mode Management:** If your design includes Light Mode, Dark Mode, or density variations (such as compact vs. spacious).
- **You define Spacing and Radius Tokens:** Numeric variables are perfect for applying consistent Gap, Padding, and Corner Radius across the system.
- **You make Dynamic Prototypes:** If you need a value to change (e.g., the price of a shopping cart or a personalized message) based on real user actions.
- **Localization Validation:** You can create String variables to test how your design looks in different languages or text lengths.

### You should use Styles when:
- **You use Gradients and Images:** Variables do not support the handling of complex color gradients; in these situations, Styles remain the only native option in Figma.
- **You apply Shadow and Blur Effects:** Everything related to `Effects` properties (inner shadows, drop shadows, layer blur) must be saved as a Style.
- **You define Typography Systems:** The best flow for saving font families, weights, sizes, and line heights remains through Text Styles.
- **You manage Layout Grids:** To define consistent design grids and squares that apply to different containers (frames).

## The Hybrid Approach: The Best Current Strategy

The most efficient and scalable design strategy consists of **using Variables to power Styles**. This workflow allows you to have the best of both worlds:

1.  **Step 1:** Create all your variables for primitive colors (e.g., `blue-500`) and semantic ones (e.g., `color-bg-primary`).
2.  **Step 2:** Create a Color Style (e.g., "Primary Background") and, instead of assigning it a manual hexadecimal value, select the `color-bg-primary` variable.

By linking Styles to Variables, you inherit the multi-mode power of variables for your visual styles, allowing for quick, global changes throughout your design system.

## Limitations and Future Considerations

Figma continues to integrate and improve these tools. The main current limitation is that typography variables do not yet granularly control all a Text Style's properties (such as lineHeight or letterSpacing) across all subscription plans. However, the future points toward a total unification under the concept of **Design Tokens**.

## Mentor's Tips

- **Don't duplicate efforts:** If a value is just a solid color, start directly with variables to take advantage of modes (themes).
- **Use semantic names:** Whether in variables or styles, the name should describe the element's **function** (e.g., `action-hover`) and not its **appearance** (e.g., `blue-600`).
- **Clean your library:** Do not maintain hundreds of styles and variables. Regularly audit your system to remove those that are not being used.
