Accesserty UI Kit
When native HTML does not cover a composite interaction, use reusable keyboard behavior, state management, and accessibility semantics. The MIT-licensed components work in plain HTML and major frontend frameworks.
When the UI Kit is a good fit
Reuse interaction behavior: each component centralizes the keyboard behavior, state synchronization, and semantics required by its pattern, reducing inconsistency across projects.
Fit an existing design and language system: CSS variables, Shadow Parts, and configurable interface text let each product supply its own visual tokens and translations.
Use components across stacks: they work with plain HTML, Vue, React, and Angular. Frameworks may still require custom-element configuration, event bindings, or a thin wrapper, so test the integration in your target stack.
Who is Accesserty UI Kit For?
- Design System Architects
Use tested interaction patterns, text contracts, and style variables as a design-system foundation, then add the integration layer required by your organization's stack.
- Frontend Developers
Reuse the component's keyboard and state behavior instead of rebuilding accordion, tabs, tree, or dropdown patterns. Overall page accessibility still depends on content, flows, and integration.
- Agencies & Freelancers
Reuse the same components and test baseline across projects instead of maintaining separate interaction implementations. Complete sites still require manual and assistive-technology testing before delivery.
How to Start Building?
Choose the right component, integrate it, and verify the result
- Step 1. Start by checking native HTML
Prefer native button, input, select, dialog, and other elements when they already meet the need. Choose a UI Kit component for composite interaction patterns.
- Step 2. Pick from Playground
Use the Playground to inspect components, adjust available options, and copy HTML and CSS variables as an integration starting point.
- Step 3. Run Everywhere
Load the package in plain HTML or the target framework, provide translated text, and apply design tokens. Then verify the integrated flow with keyboard and screen-reader testing.

Frequently asked questions
Accesserty UI Kit is an open-source Web Component library that follows an HTML-first approach. It provides reusable keyboard behavior, state handling, semantic structure, internationalized text contracts, and styling hooks for more consistent interactive components.
It can be used with plain HTML, React, Vue, and Angular, but each framework may still require custom-element schema configuration, event typing, or thin wrappers. Validate forms, events, and server-side rendering against your actual framework version.
The UI Kit places repeatable keyboard behavior, state synchronization, and semantic structure inside components, reducing repeated implementation work. It cannot make an entire page WCAG-conformant automatically; content, labels, flows, integration, and manual testing remain the implementer’s responsibility.
Yes. The source is available under the MIT License on GitHub (github.com/Accesserty/UI-Kit), with CSS variables, CSS parts, internationalized text attributes, demos, and tests for integration into your own design system.
