A fully updated guide to Figma's most powerful features, built around a new project and refreshed interface, giving you everything you need to design adaptive UIs, prototype realistic flows, and streamline handoff with Dev Mode Key Features Third edition of the bestselling book, updated with a new project, refreshed interface, and the latest design trends Build adaptive, production-ready UIs with variables, modes, components, variants, AI, and Auto Layout Prototype branched flows with conditional interactions and interactive components Book Description Figma has evolved, and so should your workflow. In this fully updated third edition of Designing and Prototyping Interfaces with Figma, you will explore the platform’s most powerful additions, including Variables, Conditional Prototyping, and a redesigned interface that reshapes how you work. This edition is built around a new, real-world project that takes you from brief to handoff and anchors every concept in practical, day-to-day design tasks. Across the project, you will create responsive layouts with Auto Layout, components, and variants; build scalable design systems; and prototype realistic, branched flows with conditional interactions. You will test on devices, collect feedback, and iterate with confidence, applying patterns and checklists that translate directly to team workflows and real product constraints. Collaboration gets equal focus. You will learn how Dev Mode bridges designers and developers for a smoother, more structured handoff with clear specs and variable-aware inspection. The book closes with a pragmatic look at emerging AI-powered tools, helping you evaluate where they might add value without replacing your creative judgment. Whether you are new to UI/UX or sharpening your practice, you will come away with a proven workflow to ship adaptive, production-ready designs. What you will learn Wireframe mobile-first with vectors, using shape tools, the Pen, and vector networks before pixels Use Variables and Modes to manage content, states, and themes at scale Prototype realistic flows with transitions, Smart Animate, overlays, and interactive components Make layouts truly responsive with Auto Layout, nesting, resizing, and constraints Build, document, and maintain scalable design systems with Components, Styles, and Dev Mode for handoff Explore AI plugins as an optional aid to support, not replace, your design workflow Who this book is for This book is for aspiring UX/UI designers who want to get started with Figma as well as established designers who want to migrate to Figma from other design tools. This guide will provide you with a walkthrough of the entire process of creating a full-fledged prototype for a responsive interface using all the tools and features that Figma has to offer. As a result, this book is suitable for both UX and UI designers, product and graphic designers, as well as anyone who wants to explore the complete design process from scratch.
