Development considerations Focus handling To support keyboard navigation, please take care of correct focus handling after closing the Banner with ESC or Enter key: The trigger element (e.g. a button) which has opened the Banner must receive focus state again after the Banner is closed. This is important to keep focus order consistent. ARIA live announcements The Banner component uses role="status" and role="alert" to announce content changes for assistive technologies, but only if the component is pre-rendered and the content is added dynamically.

Global settingsThemeChanges the theme of the application and any Porsche Design System component. It's possible to choose between forced theme light and dark. It's also possible to use auto, which applies light or dark theme depending on the operating system settings automatically.LightDarkAuto (sync with operating system)DirectionThe 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%
