Theme UI allows us to design and write coherent and consistent UIs. At its core, it uses the System UI theme specification as a reliable approach for consolidating branding compliance across web applications.

The Controlled Styled Editor is a (very early stage) proof of concept to empower designers to create interactive layouts based on the Theme UI design system principles applied in your React components.

Under the hood, it uses a custom JSX Pragma to handle element selection and Theme UI based style injection. It does this by extending the Theme UI JSX Pragma.

At its very core, it uses the Theme UI / System UI specification for editing styles within the theme properties style editor. Your design adjustments will be compliant with your design system.

It also uses Theme Query under the hood which is a very small utility function I wrote to easily query theme properties.

On the other hand, we want to make accessibility compliance checks more visual when you edit the style of your components. Based on the WCAG and theme property control we can currently check the color contrast compliance of your components. See at ease if your changes are AA and AAA compliant.

The concept and aspirations behind the Controlled Styled Editor are to move the barriers between design and development concerns by automating many of the overlapping processes. For this to become a reality we need to support data input from tools like Framer X and Figma to dynamically generate themes.

We also need to connect with external component libraries.

Accessibility color contrast check is only the beginning of making accessibility edits more visual. We would like to implement:

• Readability checks
• HTML semantic checks
• A built-in screen reader simulator using the Web Speech API

We would like to abstract System UI themes as a GraphQL queries API instead of binding components with code, we could bind the GraphQL data directly into React components, offering an alternative form of decoupling. Combined with a MetaCSSQuery (MCQ) custom prop for resolving into a style object.

The Controlled Styled Editor is a proof of concept. It's by no means production-ready. A lot of refactoring and changes needs to done in the following areas:

• Improve the UX of the Mini Editor select (react-select) by properly handling style properties updates when selecting a new component
• Improve the accessibility color contrast display. Allowing to calculate the contrast ratio of a parent component background with a child's color. Currently only calculates the background and color of a single component.
• Include missing CSS properties from our map-controlled-styles
• Improve the underlying UI/UX
• Write unit tests for custom pragma, context, and components.
