FlatColorPicker Accessibility
Out of the box, the Kendo React FlatColorPicker provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The FlatColorPicker is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.
WAI-ARIA
This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.
The FlatColorPicker contains in itself ColorGradient, ColorPalette, a UI to switch between them, Cancel, Apply, and a button to reset its value. All the containing elements must implement their own specification apart from the ColorGradient element where some changes are required.
FlatColorPicker Wrapping Element
| Selector | Attribute | Usage |
|---|---|---|
.k-flatcolorpicker | role=textbox | The focusable wrapper of the component should be considered a textbox. That signifies it has a value that could be submitted. |
aria-label or aria-labelledby | The component needs an accessible name to be assigned to it. Must also include the currently selected value in the component. | |
aria-invalid=true | Attribute is rendered only when the selected value in the component is not valid against the current validation rules. | |
tabindex=0 | The element must be focusable. | |
.k-flatcolorpicker.k-disabled | aria-disabled=true | Attribute is rendered only when the ColorPalette is disabled. |
ColorGradient
| Selector | Attribute | Usage |
|---|---|---|
.k-colorgradient | role=none/ | The ColorGradient element must have its role removed. |
aria-label | The ColorGradient element must have its aria-label attribute removed. | |
tabindex=-1/ | The ColorGradient must be removed from the page tab sequence. |
