Motion Table of Contents Usage Duration When objects move within a limited area, shorter durations are needed, compared to objects that cover larger distances. The duration of an animation directly affects the perceived lag time for users. To prevent this, it is essential to ensure that motion is swift, subtle, and purposeful. CSS variableDurationUsage--pds-duration-short0.25sFor hover effects, consider elements like Buttons, Checkboxes, Switches, or the display of Popovers.--pds-duration-moderate0.4sBest suited for elements that require moderate motion, such as the Slide transitions in Carousels, Modals, and Link-Tiles.--pds-duration-long0.6sThis duration is ideal for creating longer, more deliberate animations. It's commonly used for animations associated with Notifications and Flyouts, where a slightly slower and more controlled motion is desired.--pds-duration-very-long1.2sReserved for the longest animations, this duration is perfect for elements like Spinners and Skeleton loaders, where a very deliberate and gradual animation is necessary to convey loading or progress. Easing Effects are the key for turning components from static to interactive and keeping UI elements alive.

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%
