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.
