You’re showing CSS custom properties (CSS variables) likely used by a UI framework to control an animation. Brief explanation:
- –sd-animation: sd-fadeIn;
- Selects the animation preset named “sd-fadeIn” (a keyframes-based animation provided by the library or stylesheet).
- –sd-duration: 0ms;
- Duration of the animation. 0ms means the animation runs instantly (no visible animation).
- –sd-easing: ease-in;
- Timing function controlling acceleration; “ease-in” starts slowly and speeds up toward the end.
Practical notes:
- With duration 0ms the easing has no visible effect — change duration to >0 (e.g., 200ms–500ms) to see easing.
- Ensure the named animation (sd-fadeIn) is defined with @keyframes or provided by the framework.
- You can override these variables on elements or root (:root) to change animation behavior globally or per-component.
- Example adjustment to enable a smooth fade-in:
–sd-animation: sd-fadeIn;–sd-duration: 300ms;–sd-easing: ease-out;
