Scroller Table of Contents Accessibility support Keyboard Key / stateFunctionTab, Shift-TabMoves focus to the scroll container or to next (or previous) focusable element.Arrow left, Arrow rightScrolls the container. ARIA enhancements External ARIA provided by the aria property: ARIAUsagerole="VALUE"Defines the semantic role of the scroll container (e.g. list, tablist).aria-label="STRING"Defines an accessible name when the scroll region purpose is not obvious.aria-description="STRING"Adds supplementary context for the scroll region. Development considerations Common do's and don'ts Do provide an accessible name through the aria prop when the scroll region purpose is not obvious from context. Do pass aria-label and aria-description via the aria prop, not as host attributes. Don't add native aria-* attributes directly on the component host. Integration examples
ARIA on component host vs aria prop❌ Anti-pattern
<p-scroller aria-label="Section tags" aria-description="Section tags for the section overview">
  <p-tag>
    Overview
  </p-tag>

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%
