Accessibility
Implement ARIA standards and best practices to build inclusive, accessible data grids.
Accessibility ensures that all users can navigate and interact with your application, regardless of ability. LyteNyte Grid provides robust, standards-compliant accessibility features. This guide outlines the key capabilities and best practices.
Accessibility Compliance
LyteNyte Grid complies with WCAG 2.0 guidelines at levels A, AA, and AAA. Level AA compliance typically satisfies ADA standards.
The grid uses ARIA (Accessible Rich Internet Applications) attributes on rows, cells, and headers. Screen readers interpret these attributes to help visually impaired users understand the grid’s structure and content.
DOM Ordering
LyteNyte Grid renders cells and headers in natural DOM order, even when virtualization is enabled. This ensures that screen reader users can correctly parse content. No special configuration is required to enhance the grid’s accessibility.
ARIA Roles and Properties
LyteNyte Grid applies ARIA roles and properties to remain spec-compliant and accessible.
Grid Roles
The main container uses role="grid". It also applies:
aria-rowcount: total rows in the grid.aria-colcount: total columns in the grid.aria-multiselectable="true": only when multiple row selection is enabled.
Row Roles
The grid uses role="row" for individual rows and role="rowgroup" for
row containers.
For role="row", the grid adds:
aria-rowindex: the row’s position in the grid.aria-selected: whether the row is selected.
Header Cell Roles
Headers use role="columnheader" and may include:
aria-colindex: the column’s position in the grid.aria-expanded: open or collapsed state.
Grid Cell Roles
Cells use role="gridcell" and may include:
aria-colindex: the column’s position in the grid.
Considerations for Visual Accessibility
Screen Readers
LyteNyte Grid works with major screen readers, including:
The grid follows W3C standards to ensure a smooth, predictable reading experience.
Color Accessibility
Roughly 300 million people worldwide experience some form of color blindness (source). Use accessible colors to meet AA standards and maintain readability.
LyteNyte Grid provides prebuilt grid themes and color design tokens. These themes are designed to be accessible and spec-compliant.
If you don’t use a built-in LyteNyte Grid theme and instead customize your own, choose a high-contrast palette to maintain accessibility. Recommended palettes include:
Accessible colors ensure data remains legible for everyone. LyteNyte Grid supports accessible implementations. Use correct ARIA roles, test with screen readers, and validate your color choices. Reassess with assistive technology whenever you update the UI.
Next Steps
