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

• –sd-animation: sd-fadeIn;
  • Likely selects a named keyframe or animation preset (here, “sd-fadeIn” — a fade-in effect).
• –sd-duration: 0ms;
  • Duration of the animation; 0ms means no visible animation (instant).
• –sd-easing: ease-in;
  • Timing function controlling animation acceleration (starts slowly, then speeds up).

Practical notes:

• If these are applied to an element, you need corresponding CSS that reads them, e.g.:
  .element {animation-name: var(–sd-animation);  animation-duration: var(–sd-duration);  animation-timing-function: var(–sd-easing);}

• Ensure –sd-animation matches a defined @keyframes name (e.g., @keyframes sd-fadeIn { from { opacity:0 } to { opacity:1 } }).
• Set a nonzero –sd-duration (e.g., 300ms) to see motion; combine with animation-delay, fill-mode, and iteration-count as needed.
