These look like CSS custom properties (CSS variables) used by a component or design system to control an animation. Briefly:

• –sd-animation: sd-fadeIn;
  • Name of the animation to apply. Likely refers to a keyframes animation called “sd-fadeIn” (a system-specific naming convention).
• –sd-duration: 250ms;
  • Duration of the animation (250 milliseconds).
• –sd-easing: ease-in;
  • Timing function controlling acceleration (starts slowly then speeds up).

How they’re used (example):

.element {animation-name: var(–sd-animation);  animation-duration: var(–sd-duration, 250ms);  animation-timing-function: var(–sd-easing, ease-in);  animation-fill-mode: both;}@keyframes sd-fadeIn {  from { opacity: 0; transform: translateY(6px); }  to   { opacity: 1; transform: translateY(0); }}

Notes:

• Ensure the referenced keyframes (sd-fadeIn) exist.
• You can override these variables on specific elements or in different states (e.g., :hover).
• Use sensible fallbacks when reading custom properties (as shown) for broader browser support.
