ARIA enhancements Internal ARIA that is managed by the component: ARIAUsagearia-describedby="IDREF"Defines the accessible description combined with the status message.role="status", role="alert"When message and state or loading prop change, the status message is announced.aria-hidden="true"If required attribute is set, the visible asterisk indicator is hidden from assistive technologies.aria-invalid="true"If error state is set.aria-live="polite"If the maxlength attribute is present, the counter is announced via ARIA live region. Development considerations Disabled state In general, avoid using the disabled state. Disabled elements are no longer focusable and may be missed by screen reader users. They can also confuse sighted users if the reason they are disabled is not made clear. Common do's and don'ts Do provide a descriptive label, especially for open text questions. Do use helper text to describe expected format, length, or sensitive content rules. Do surface validation with state/message so screen readers get updates. Don't use placeholder-only instructions. Don't use hide-label without an accessible name. Integration examples

Global settingsColor SchemeAll color tokens use the light-dark() CSS function. Set the theme via the CSS color-scheme property: light for light mode, dark for dark mode, or light dark to follow the user's system preference.LightDarkLight DarkDirectionThe dir global attribute in HTML changes the direction of text and other content within an element. It's most often used on the <html> tag to set the entire page's direction, which is crucial for supporting languages that are written from right to left (RTL), such as Arabic and Hebrew. For example, using <html dir="rtl"> makes the entire page display from right to left, adjusting the layout and text flow accordingly.LTR (left-to-right)RTL (right-to-left)Text ZoomTo ensure accessibility and comply with WCAG 2.2 AA standards, it is mandatory for web content to support text resizing up to at least 200% without loss of content or functionality. Using relative units like rem is a best practice for achieving this, as they allow the text to scale uniformly based on the user's browser settings.100%130%150%200%
