Those look like custom CSS properties (CSS variables) used by a component or animation system. Briefly:

  • –sd-animation: sd-fadeIn;

    • Defines the animation name or preset (here “sd-fadeIn”). The component or script reads this to apply a specific keyframes animation or preset behavior.
  • –sd-duration: 0ms;

    • Sets the animation duration. 0ms means the animation runs instantly (no visible transition).
  • –sd-easing: ease-in;

    • Sets the timing function for the animation, controlling its acceleration curve. “ease-in” starts slowly and speeds up.

How they work in practice:

  • A stylesheet or JS will read these variables and apply them to animation-related properties, e.g.: 
    animation-name: var(–sd-animation);animation-duration: var(–sd-duration);animation-timing-function: var(–sd-easing);
  • If duration is 0ms the animation effect will be effectively disabled; set a positive value (e.g., 300ms) to see the fade-in.
  • Ensure the named animation (sd-fadeIn) corresponds to defined @keyframes: 
    @keyframes sd-fadeIn {from { opacity: 0; transform: translateY(8px); }  to   { opacity: 1; transform: translateY(0); }}

Tips:

  • Use sensible durations (150–400ms) and matching easing for feel.
