an accessibility annotation Figma plugin
The eBay Include accessibility annotation Figma plugin is a tool to make annotating for accessibility (a11y) easier — easier for designers to spec and easier for developers to understand what is required.
The plugin was developed by members of the accessibility and design teams at eBay and is released for public use on Figma. You can view and install the latest version of the plugin here.
npm run dev
To open the plugin in development mode on Figma, point Figma to the manifest file at the root of the project.
The app consists of 2 main files:
ui.jsUI Renderer (React app the user interacts with)
code.jsFigma Code Bridge (communicate with the Figma document)
The main methods used in this plugin to communicate with Figma are:
- used to run once on plugin load: pre-load fonts and search current page for any A11y Layers
- listen for frame selection (used to start an initial scan)
- listen for Headings selection by user (accessibility step)
- if the user changes to a different page on Figma, we ask them to go back to the page they started the plugin on, or to re-start the plugin on this new page
- this listener is used for 90% of the communication between the React App and the Figma document
Figma Layer Naming and Structure
To create and read in accessibility annotations, the plugin creates Figma layers. An Accessibility Layer is created for each Figma frame that is annotated, and it follows the following structure:
[Scanned Frame Name] | Accessibility Layer | [Web or Native] ├── Landmarks Layer ├── Headings Layer ├── Reading order Layer ├── Alt text Layer ├── Contrast Layer ├── Touch target Layer ├── Text zoom Layer ├── Responsive reflow Layer └── Accessibility annotations Layer [Scanned Frame Name] Text Zoom
Using Color | Accessibility Layer | Web ├── Landmarks Layer | 207:424 │ ├── Landmarks Annotations │ └── Landmark: banner | 207:411 ├── Headings Layer | 207:444 │ ├── Heading: h3 | Color Backgrounds │ ├── Heading: h2 | How We Use Color │ └── Heading: h1 | Using Color ├── Reading order Layer | 814:1149 │ ├── Arrow 4 │ ├── Arrow 3 │ ├── Arrow 2 │ └── Start Arrow ├── Alt text Layer | 207:410 │ ├── Alt text Annotations │ └── Alt text: informative | alt text for image | original image name | 2:146 ├── Contrast Layer | 814:1297 ├── Touch target Layer | 814:1298 ├── Text zoom Layer | 122:198 ├── Responsive reflow Layer | 804:3055 └── Accessibility annotations Layer | 1210:1466 Using Color Text Zoom
