Explore Variable Types: String, Number, Color and Boolean

Figma provides four main types of variables to meet various design needs: string, number, color and boolean. If you're working with text elements, like labels or descriptions, string variables are ideal. They can change on the fly, so if you want a button to display "Submit" at one moment and switch to "Processing..." shortly after, string variables are the way to go.

Number variables come in handy when you want to adjust sizes or dimensions. Whether you're changing the height of a button or the corner radius of a card, these variables make it easy to handle numerical values. Color variables are all about aesthetics; they can hold hex codes or be adjusted with a color picker, which makes it a breeze to update the colors of various elements. Boolean variables are simple yet effective, allowing you to toggle states like visibility. They're particularly useful for showing or hiding layers based on user interactions with your design.

Learn How Variables Store Design Attributes and States

Variables don't just hold values; they represent the design attributes and states of elements within your prototype. By storing these attributes, you can create a more interactive experience. For instance, imagine a quiz app where the correct answer changes the appearance of elements based on the user's selection. By using variables, you can easily manage these states without duplicating frames for every scenario.

When you connect a variable to a design element, you create a link that allows the element to update automatically. This means any changes you make to the variable's value will be immediately shown in the design, keeping everything in sync. Whether you're adjusting a text box or altering a component’s variant, understanding how variables control these features can really boost your prototyping skills. As you explore Figma, keep in mind that these variables can simplify your design process, turning your prototypes into something that’s not only functional but also truly interactive.

Create and Organize Variable Collections

Creating variable collections is straightforward. Start by identifying the different elements in your design that will benefit from dynamic values. You might want a collection for UI states, like hover effects or button states and another for typography settings, such as font sizes or styles. Naming your collections clearly will make it easy to remember which variables belong where.

Once you’ve created your collections, you can begin adding variables to them. Think of each variable as a small piece of the puzzle that can change based on user interactions. For instance, if you have a button that changes color when hovered over, you can create a color variable specifically for that state. Organizing your variables in this manner not only keeps things neat but also allows you to make changes quickly and efficiently.

Apply Variables to Text, Dimensions and Layer Visibility

Now that you have your variable collections set up, it’s time to apply them to your design elements. This is where the magic happens! You can bind your string variables to text layers, allowing you to change text dynamically. For example, if you have a call-to-action button, you can use a string variable to update the text based on user interactions. When they click the button, the text can change from “Subscribe” to “Thank You,” creating a seamless experience.

But it doesn’t stop at text. You can also apply number variables to control dimensions, like the width or height of shapes and even adjust properties like corner radius or spacing. This means that with just a few variable updates, you can drastically alter the look and feel of your design without starting from scratch.

Layer visibility can be toggled with boolean variables, which gives you the ability to show or hide elements based on user actions. Imagine a quiz application where the next question appears only after answering the previous one. Using boolean variables, you can make that happen effortlessly. By leveraging these variables across your design, you create a more interactive and user-friendly experience that can adapt based on real-time feedback.

Incorporating variables into your Figma designs is not just a technical skill; it’s a way to think about design in a more dynamic and responsive manner. Once you get the hang of it, you’ll wonder how you ever designed without them!

Configure Prototype Interactions with Set Variable Actions

Setting variables in your prototypes is like giving your designs the ability to think and respond to user actions. To create these interactions, you start by making a prototype and choosing a trigger, such as a button click or a hover. Then, you pick the "Set variable" action, which lets you determine which variable you want to change. It's important to choose the right variable and enter a new value that matches its type whether it's a string, number, color or boolean. For instance, if you have a button that changes its text when clicked, you would set a string variable to dynamically update the text layer. This approach ensures a smooth user experience, as the interface reacts instantly to what users do.

Test and Iterate Your Variable-Driven Prototypes

Once you've set up your variables and interactions, it’s time to start testing. Take a moment to explore your prototype and ensure everything works as you expect. As you go through the interactions, pay attention to how the variables change and impact your design. It’s not just about how it looks; you also need to verify that the logic behind your variable actions is sound. If something doesn’t seem right, don’t hesitate to make changes. Experiment with your variable settings, adjust your actions and try out different triggers. This ongoing process will help you refine your prototype, making it more user-friendly and enjoyable. The awesome thing about using variables is their flexibility, so make the most of that to experiment and enhance your designs.

Write Numerical, String and Boolean Expressions

Getting started with expressions in Figma is easier than you might think. Numerical expressions could involve basic math operations, like adding or subtracting values to adjust dimensions or positions. For example, you might have a number variable for the height of a button that you want to increase by 20 pixels when it's hovered over. It's straightforward: you simply write an expression that adds 20 to the current height value.

String expressions are just as simple, allowing you to manipulate text. You can use string literals or other string variables to dynamically change what appears on the screen. If you want a label to read “Clicked!” after a button is pressed, you can set up a string expression that changes its value based on user interaction. Boolean expressions are a bit different; they deal with true or false states. For instance, you might have a boolean variable that toggles the visibility of a layer based on whether a button has been clicked. By mastering these types of expressions, you’re well on your way to creating highly interactive prototypes.

Implement If/Else Statements for Conditional Actions

Now, let’s talk about conditional logic, specifically how to implement if/else statements in your prototypes. This is where things get really interesting. If/else statements allow you to define specific outcomes based on certain conditions. For instance, you might want to change the text of a button depending on whether a user has clicked it or not. You could set up an if/else statement that checks the state of a boolean variable if it’s true, the button reads “Active”; if false, it reads “Inactive.”

Using these conditionals not only adds depth to your designs but also improves user experience by providing immediate feedback. It’s like giving your users a conversation; their actions lead to tangible responses from the interface. The beauty of conditional logic is that it can be as simple or as complex as you want. You can stack multiple conditions to create intricate behaviors that respond to various user inputs, ensuring that every interaction feels meaningful.

Stack Multiple Actions to Create Complex Interactions

Once you’ve grasped the basics of expressions and conditionals, the next step is stacking multiple actions to create complex interactions. This means you can trigger several changes simultaneously based on a single user action. For example, when a user clicks a button, you can set it up so that it not only changes the text but also modifies other variables, changes component states and even adjusts the layout of the surrounding elements.

Stacking actions allows for a more fluid experience, as it reduces the number of interactions a user needs to make to see significant changes. Imagine a dashboard where clicking one button updates multiple data points, changes graphs and adjusts visibility all in one go. It’s a powerful way to enhance your prototypes, making them feel intuitive and responsive. By learning to stack actions effectively, you can create prototypes that not only look great but also function seamlessly, providing a richer user experience.

Incorporating expressions and conditional logic into your Figma prototypes can really open up new creative possibilities. As you start experimenting, you'll see how these features can elevate your design process and lead to more engaging and interactive experiences.

Bind Variables to Component and Variant Properties

Binding variables to component and variant properties is a straightforward yet powerful process. It starts with defining the variables you want to use. These could be strings for text labels, booleans for visibility toggles or numbers for sizes. Once you've set up your variables, you can link them to specific properties of your components. For instance, if you have a button that needs to display different labels based on its state, you can bind a string variable to the button's text layer. This means that whenever the variable changes, the button automatically updates its label without needing a separate instance for each variation.

This binding also extends to component variants. If you have a button that can be in different states, like "default," "hover," or "clicked," you can use boolean variables to determine which variant is displayed. By employing this method, your prototypes become much more adaptable. Instead of creating multiple components for every state, you can rely on a single, versatile component that changes dynamically based on the user's interactions. This not only streamlines your design process but also enhances the overall interactivity of your prototype.

Create Interactive Components Using Variable States

Creating interactive components with variable states is where the magic truly happens. Let’s say you have a card component that displays additional information when hovered over. By introducing a boolean variable let’s call it isHovered you can toggle the visibility of elements within the card. When the user hovers over the card, the variable changes to true, revealing hidden details like descriptions or buttons. This kind of interaction makes your prototypes feel more engaging and allows users to explore various functionalities without overwhelming them with too much information at once.

You can take this idea even further by combining multiple variables. Picture a complex form where the visibility of each field is based on what the user inputs. By skillfully using variables, you can set it up so that certain parts of the form only show up when specific conditions are met. This approach not only helps guide users through the process but also keeps the interface clean and user-friendly. The potential is limitless and as you try out different variable states, you’ll discover just how much more dynamic your prototypes can be.

Use Variable Modes to Switch Contexts Efficiently

When setting up variable modes, think of them as a way to give your prototypes a bit of personality each mode can reflect a different scenario or state. For example, if you're designing a button that changes its look based on user interaction, you can create modes for its default appearance, hover effect and clicked state. This approach allows you to switch between these states easily, without needing to manage multiple variable setups or create extra components.

Using modes makes it simpler to manage interactions because you can define a single variable and just toggle between its modes as needed. This is particularly effective in scenarios where you want to keep the user experience seamless. For example, consider a scenario where the design changes in response to user input; with variable modes, you can switch the button's visual state without complicating the prototype structure. It’s like having a smart assistant that knows when to change based on the context, making your design process feel more intuitive and less cluttered.

Integrating different modes into your prototyping process can significantly improve your efficiency and increase the interactivity of your designs. As you explore Figma, remember that these advanced features are meant to inspire your creativity and streamline your workflow.
