As design systems grow, the complexity of managing components often leads to "component bloating." To solve this, senior designers turn to a powerful technique: Figma Slots.

What is a Figma Slot?

A slot is essentially a placeholder within a main component that allows for flexible content injection. Instead of creating dozens of variations for a single card or modal, you create one "Master Component" with a slot that can be swapped for any local instance.

Why You Should Use Slots

• Reduced Component Debt: Stop creating a new component for every minor layout change.
• Infinite Flexibility: You can inject forms, images, or nested lists into a standard container without breaking the master link.
• Global Updates: When you change the padding or border-radius of the container, every instance across your file updates instantly, regardless of what is inside the slot.

The Workflow: How to Implement Slots

To get started, create a simple "Placeholder" component. Place this inside your complex components (like Modals, Sidebars, or Cards). When you use that component in your design, simply use the "Instance Swap" menu to replace the placeholder with the specific content your layout requires.

The Senior Perspective

Slots shift your focus from "drawing screens" to "building systems." By mastering this architecture, you ensure your design system remains lean, maintainable, and developer-friendly.
