Basic concepts

When you work in Plasmic, you work on a project. You can share projects, inviting other people as editors or commenters.

Projects are comprised of the following:

  • Components, or reusable chunks of UI, similar to symbols in Sketch or components in Figma. We describe these in detail below.
  • Pages, or web pages, which have associated URL routes—not to be confused with “pages” from Figma/Sketch.
  • Reusable styles including tokens and mixins. We describe these in detail below.
  • Arenas — A canvas or workspace, analogous to “pages” in Figma/Sketch. This is where artboards are laid out. A project has multiple arenas you can switch between. All arenas in the same project share the same set of components and reusable styles. These are optional, and are for users who are more comfortable with design tools.
  • Artboard — The parts of your arena that house your content. Unlike Figma/Sketch, you can only draw in artboards, not in the space between artboards. An artboard can either be used as a scratch pad, or for editing the master instance of your components. The artboard can also be independently sized (width/height) and placed anywhere in the arena.

Studio UI

The Studio UI has majorly five sections - the top toolbar, the canvas, the left bar, the right bar, and the variants toolbar.

The canvas is the large area in the middle of the Studio UI showing the arena you’re currently viewing.

The left bar contains a few tabs:

  • Tree shows the structure of artboards (and the component in it) in your arena, similar to the layers panel in other tools. A key difference is that the ordering is reversed from how layers work in other tools; we go top-down rather than bottom-up, so the elements lower on the list will draw on top of elements higher on the list.
  • Gallery shows the components you have built, as well as some basic building blocks you can use in your designs.
  • Assets shows the reusable styles defined in the project.

The right bar contains info about what you’ve currently selected. It shows the properties of the selected element or artboard for you to inspect/edit.

The variants toolbar shows what variants are currently being viewed and lets you toggle recording overrides to any of them.


A component is a reusable chunk of UI, similar to symbols in Sketch or components in Figma. You can have small components like Buttons or Icons, large components for a whole Screen or Webpage, and things in between such as Login Form, Tweet, etc. You can have many instances of any component.

A component is built up of a tree of elements, similar to layers in other tools. These are either primitive elements like boxes, text elements, or input fields, or instances of other components. A component always has exactly one root element, usually a box containing other elements.

As an example, a ProfileCard component containing a picture and name side by side might be structured as follows. It has a root box that’s a horizontal stack, which arranges an image and a text element side by side.

Once you have built a component, you can add instances of that component in other artboards anywhere you can add normal elements. You can thus compose instances of smaller components into larger and more complex components. Below, we drop in three instances of the ProfileCard into a new artboard.

Wherever you have an instance of a component, you can double-click on it to drill into editing the component master in Spotlight Mode. You can thus edit any component master in-place, with a spotlight shown on that component. This is in contrast to needing to navigate to the component master’s specific physical location in other design tools.

Below we introduce the core concepts in Plasmic that pertain to components.


A page or component can have multiple variants that let the page or component appear differently in different circumstances.

The most common use is for responsive design of pages—see responsive design using screen variants. These are what are called global variants.

As another example, a Button component might have Small, Medium, and Large variants, and also Primary, Secondary, and Danger variants. This section will just focus on such component-specific variants.

All user-defined variants are organized into variant groups. For example, you might have a variant group called “Size” containing variants Small, Medium, and Large, as well as a variant group called “Type” containing variants Primary, Secondary, and Danger.

All components also have a base variant that defines its default appearance. You can see the organization in the floating Component Panel, which is where you can create and delete variant groups and variants.

By default, variant groups are single-choice groups, so your button can be either Primary or Secondary but not both. Variants in any group are also optional—your instances of Button can leave “Type” unset, so is neither Primary/Secondary; in that case, the Button will simply be displaying its “base” state.

The non-base variants hold style settings that override styles in the base variant. By default a variant inherits all the styles of the base variant. For instance, your Button’s Large variant might inherit all the same styles from of the Button’s base variant, but override only the font size of the button text. If you later make the Button rounded (in the base variant), your Large Button also becomes rounded.

This is also what lets you see a Button in a combination of variants. For instance, you can view a Button whose Size is Large and Type is Primary. Again, each variant only overrides specific styles, so Large overrides the font size, and Primary overrides the background color and text color.

Button Component with different combinations of Size and Type variants.

We recommend that you put most of the Component styles in the base variant, and only put necessary override styles in the other variants; this allows you to share as much style as possible between the different variants of your component.

To make style changes to a specific variant, simply click on the desired variant in the Component Panel. The selected variant will light up in red, indicating that you are now recording changes for that variant. As you make changes in the right panel, a blue dot next to a style setting will indicate that it’s defined in the current variant, overriding the base variant. You can clear the override by right-clicking it and choosing Remove Style. To stop making style changes to a variant and go back to the base variant, simply select the base variant again in the Component Panel.

So far, we’ve said that variants contain style settings, but in fact they also hold other settings:

  • Visibility — whether the node is rendered at all or omitted in a variant. For instance, a sidebar in a screen design might be visible only on the desktop variant and not a mobile variant. Visibility can be toggled with the eye icon in the Tree in the left sidebar. Hide the downloadIcon for current variant

  • Non-style element attributes, such as the placeholder for an input textbox, or the src for an image. Attributes section of the selected element recorded under current variant

  • If your component contains other component instances, then what variant(s) you want active on those other components. For example, a ProfileCard component might contain a Button instance for following/unfollowing a user, which we want to enable or disable depending on whether the current user is following the person in the ProfileCard. The ProfileCard then might have two variants — a “following” variant, where the Button instance has the “Type = Disabled” variant activated, and a “not-following” variant, where the Button instance has the “Type = Primary” variant activated. The ProfileCard component in “following” variant with the followBtn with “Type=Disabled“ variant activated

Interaction Variants

You may want to define variants that correspond to common interactions, such as the hovered and pressed states of a Button. You can create special interaction variants for some fundamental interaction types, including Hovered, Pressed, Disabled, and Focused. They’re special because when you switch into Preview mode (by pressing the Play button in the top toolbar), you can immediately see these variants in action by interacting with your design.

You can also define these to be any combination of the above. For instance, you may want an interaction variant for when the button is “Hovered and Not Disabled.”

Interaction variants are always defined as nested under some other (normal) variant.


Slots are sections of a component that are meant for component instances to fill in with arbitrary content. They are like “holes” in a component.

For example, a Button component may be responsible for the border / background / font color / etc., but it can be customized with any button content. One Button can say “OK,” another “Cancel,” and another an icon alongside “Submit.”

Usually slots have default content. The Button’s default slot might just be “Button text here.”

Components can also have multiple slots. A Card component might have a header slot and a body slot.

To create a slot, right-click any element and choose “Convert To Slot.” This exposes a slot on the component that element belongs to. The element you converted becomes the default content for the slot.

Then, wherever you have an instance of that component, you can directly manipulate the slot contents. For instance, you can simply double click on the Button’s text to type in something else.

If you don’t override the slot, it will always reflect the current default contents (i.e. it reflects the update you made to the default contents).

Slots can be compared with overrides in other design tools, but with key differences:

  • Slots are a way to override that is officially blessed by the component author. This is critical to allowing a design system to scale and to informing component consumers what are appropriate ways to override a component.
  • Slots allow flexible component composition. It should be easy to plug in arbitrary content into a slot, including multiple other elements and components.


Props are settings to configure on a component instance. Variant groups and slots are types of props on a component.

Besides variants and slots, you can take any element in the component and expose its non-style attributes as props. For instance, if you have a “Labeled Input” component containing an input textbox, you can expose the “placeholder” as a prop of the “Labeled Input” component, so that each instance of “Labeled Input” can specify its own placeholder.

You can also add Meta Props to attach arbitrary metadata to components, for code instrumentation purposes.

Element Visibility

You can hide and show elements for different component or global variants. In the Visibility section, there are three options:

Visibility options
  • Visible — the element is shown.
  • Rendered but invisible (aka display:none). Here, the element you are hiding will still be rendered to the page (the DOM elements will be created and styled), but just hidden with css property display:none. This means we can hide and show the element using just css without running any javascript, which is a great fit for when you’re targeting interaction variants (like :hover) or responsive breakpoints (media queries), which can also be triggered by css selectors without running javascript.
  • Not rendered. Here, the element you are hiding will not be rendered at all; in React speak, this is conditional rendering, like doing {ifTrue && <Blah />}. This is a good fit when you’re hiding components that will be doing data fetches or creating other side effects that you don’t need, or when you’re hiding large chunks of content, like in a tabbed UI, and you don’t want to pay the cost of rendering content unless they are shown.

Which one should you use?

  • For targeting interaction variants and responsive breakpoints, display:none is usually what you want. This will give you a more robust result not just for SSR but :hover etc as well.
  • For other normal component variants, conditional rendering probably makes more sense. Toggling these variants requires running javascript anyway, and this avoids rendering unnecessary content or firing errant fetches and side effects, making it easier to reason about the state of your application.
  • For mostly static pages, you can generally stick with display:none; for stateful applications with lots of dynamic instrumentations, you’ll want to consider the above implications more carefully.
  • There are many good exceptions to these rules, which is why the choice is available to you!

Reusable Styles

Components are one powerful tool to achieve reuse and maintain consistency throughout your design. Style tokens and style mixins are another such set of tools, focused on styling and appearance.

Style Tokens

Style tokens are simple reusable named style values. Currently, Plasmic supports defining color tokens. For instance, rather than using the color “#0070e0” everywhere, you can define it as your app’s “Accent Color” and use that anywhere you can apply a color (background colors, text colors, gradient colors, etc.).

You can define these as-you-go anywhere you have a color picker, or you can create them directly from the Assets tab in the left sidebar. The Assets tab is also where you can see a list of all your existing color tokens.

Then whenever you pull up the color picker, you can select a color token that you’ve previously defined.

Color tokens can be defined in terms of other tokens. For instance, you may have a base color scale that defines tokens “Blue-100” through “Blue-900.” Then on top of that, you may define a color token “Accent Color” as always being “Blue-700.” If you later adjust your color scale, Accent Color is similarly updated.

Style Mixins

Style mixins are reusable bundles of styles. Whereas a token is just a simple value (such as a specific color like “#0070e0” without caring if it’s used as a background color, text color, gradient color, etc.), a mixins might specify that:

  • the background color is “#0070e0”
  • the padding is 10px all around
  • the drop shadow should be dark gray, be offset 10px and have a 10px blur

Basically, most of the usual style settings available to you in the right sidebar can be stored into a mixin.

Mixins are listed in the Assets tab in the left sidebar.

You can create new ones there, or if you already have styles defined on some element, you can extract some or all of those styles into a mixin.

Then you can apply this on any (non-component) element, and it will adopt that visual appearance.

All the styles that come from a mixin have a green dot indicator in the right panel.

Layout System

The layout system in Plasmic is designed to be uncompromising, so that you can express a much richer set of layouts than what is available in today’s design tool auto-layout features, while remaining confident that these can be directly represented in the target platform.

Boxes and Stacks

Layout is accomplished using boxes, a basic element type. It acts as a container and can hold other elements as children. A box can be a free box whose children have free-floating positioning (“absolute positioning” in CSS terminology), or automatically lay them out in a horizontal or vertical stack. You can insert these from the Gallery, or draw these using the top toolbar icons:

In free boxes, you can specify whether the item is anchored to the top/left of its parent (the default), or perhaps the top/right. You can even anchor to both the left and right of the parent, so that resizing the parent resizes the child in a way that maintains fixed left/right margin widths. This is similar to Constraint Layout in other design tools.

A horizontal or vertical stack arranges its children in a row or column automatically. This frees designers up from worrying about maintaining exact placement, and is how most UIs in production behave.

Stacks can specify a default gap between their items. Stacks also have the ability to wrap, and as such can specify a cross-axis gap (e.g., a row gap for a horizontal stack).

Stacks can also specify padding (as shown above), which is how much they nudge their children inward from their own border.

When you draw a box (including stacks) onto the screen around some other elements, those elements will become nested as children in the newly drawn box.

You can also take a box and press “Shift+A” to cycle through the auto-layout configurations. If it’s currently a free container, we’ll guess what is the desired stack layout (horizontal/vertical) from the positions of the items in the box.

Although by default stacks imply the children are auto laid out, you can in fact set any particular stack child to be free-floating, which is occasionally useful for placing the red badge in this example:


Depending on the layout, an element’s size (width and/or height) can be:

  • Fixed size, e.g. 32px
  • Hugging or “tightly wrapping” its own content. For instance, a button should always wrap its own text content with constant padding.
  • Stretching to fill its parent. For instance, a Nav Menu component should always stretch to span the width of the screen.

You can mix these on different axes—while the Nav Menu should stretch horizontally, perhaps it should be hug its content vertically.

You can also set more advanced layout configurations using min and max sizing constraints. For instance, you want a button to hug its text, but also want a minimum width and/or maximum width (forcing the text to wrap or truncate).


An artboard is just a view of a component. You can have many artboards viewing a component, each one viewing it in a different variant.

Normally these are managed for you, since you’re always focused on some page or component. But in arenas, you can freely create and arrange your artboards.

When you create a “scratch” artboard, it actually isn’t associated with a component at all. It’s just a blank canvas for you to draw on—a scratch space. You can convert a scratch artboard into a component, after which the artboard will be a view of that component. Do so by selecting an artboard and clicking this button in the right sidebar.

When an artboard is a view of a component, we call that a bound artboard. You are directly editing the component master in that artboard. (You can also edit the component master anywhere there is an instance of a component—double-clicking instances drills into editing the master in Spotlight Mode.)

Global variants

Earlier we describe variants, which are always specific to a component. For instance, the primary variant of a button.

However, if you want to re-theme the entire app, such as adding a “Dark mode,” you probably want to change many components together.

Global variants are similar to normal (component-specific) variants, in that components can appear differently in different global variants. However, global variants themselves are global to the entire project, meaning that any component can have specific style settings defined under a single “Dark mode” variant.

Besides dark mode, there are many other use cases for global variants, where you want many components in the app to change together:

  • platform—web vs. iOS vs. Android
  • screen size—mobile vs. desktop
  • palette—light mode vs. dark mode vs. sepia vs. high-contrast dark
  • locale—LTR vs. RTL languages
  • brand—Facebook vs. Instagram vs. WhatsApp, or Material vs. Cloud Material
  • configurations—Gmail roomy vs. dense

For instance, a global variant for iOS vs. Android might switch over the look of many components:

This is a particularly powerful feature for designing robust design system components that allow designers to view their designs across multiple contexts.

To create and manage global variants, select into any component to bring up the floating variants panel, and in the bottom section you’ll see the global variants listed, with the ability to create more.

You can then set any artboard to render its contents in the context of some global variant(s).

Responsive design using screen variants

There’s a special global variant group called “Screen” variants, built in to all projects. These are treated specially because they can specify min and max viewport widths at which they kick in. For instance, if you’re doing mobile-first design but want to make adjustments for the desktop, you can create a screen variant called “Desktop” that activates on devices over 300px wide. Then, whenever you have an artboard that is over 300px, this Desktop variant will be automatically shown by default.
