Notifications Table of Contents Notifications are an important method of communicating with users and providing feedback. Their main aim should be to help users perform a task and not necessarily interfere or get in the way of users while using your product. Ensure your notifications are relevant, timely, and informative. Keep in Mind: Highly frequented or disruptive Notifications can have a negative impact on the user's experience. When to use In order to find the right notification type for your use case, we have defined some decision-making rules for you: Go to the Decision Tree Types/Behavior ComponentsPlacementFollow-up ActionHideCriticalityStatesForm elements (Inline Validation)Below form elementYesResolvedLowSuccess, ErrorToastBottom, LeftNoAutomatically (6s)Low/MediumNeutral, SuccessInline NotificationBefore/After ContentYesResolved/DismissMediumNeutral, Success, Warning, ErrorBannerTop, CenterYesResolved/DismissMedium/HighNeutral, Warning, ErrorModalCenterYesResolved/DismissHighNeutral, Warning, Error Layer order Important: All elements are rendered on the browsers #top-layer so a manual ordering of z-index will have no effect, instead the browser renders the element on top of everything which was triggered to be shown last, meet the top layer: a solution to z-index:10000.

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%
