Curated

These are CSS custom properties (CSS variables) used to configure a scoped animation. Explanation:

  • –sd-animation: sd-fadeIn;

    • Defines the animation name or preset. Here it likely references a keyframes rule or a named animation preset called “sd-fadeIn” (a fade-in effect).
  • –sd-duration: 0ms;

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

    • Sets the timing function for the animation; “ease-in” starts slow and speeds up.

How they’re typically used (example):

.element {animation-name: var(–sd-animation, none);  animation-duration: var(–sd-duration, 300ms);  animation-timing-function: var(–sd-easing, ease);}

Notes:

  • With duration 0ms the easing has no visible effect because there’s no time to interpolate.
  • Ensure the referenced animation (sd-fadeIn) is defined with @keyframes or provided by a framework.
