commonsymbols.comCross-Platform Annotations
Markup-compatible symbols with standardized roles, states, and accessibility attributes.
Cross-Platform Annotations offer symbols encoded directly with roles, states, and aria attributes, ensuring they behave predictably in HTML, ARIA, and JavaScript frameworks. This avoids the common issue of symbols rendering as unlabelled characters or losing semantic meaning across platforms. Each symbol comes with tested attribute sets that map to live DOM behaviors.
These glyphs are delivered in formats that preserve their semantic metadata—including SVGs with embedded accessibility tags and WOFF2 font files with preassigned unicode Private Use Area codes. This allows developers to use them confidently in interactive components, knowing screen readers and assistive tools will interpret them consistently regardless of browser or device.
We standardize state representations like disabled, pressed, and active so teams do not have to define their own semantics from scratch. All entries have been validated using open-source accessibility testing tools to confirm compliance with WAI-ARIA specifications, reducing the risk of inaccessible deployments.
