Crest Table of Contents Accessibility support ARIA enhancements External ARIA provided by the aria property: ARIAUsagearia-labelDefines a string value that labels the interactive element.aria-currentExposes the current state of the link.aria-haspopupDefines that the link opens a popup (e.g. dialog). Development considerations Common do's and don'ts Do pass ARIA attributes through the aria prop when the crest is linked. Do provide a descriptive aria-label for linked crests, for example "Porsche home". Don't add native aria-* attributes directly on the component host. 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%
